functions, and block module is adopted for the structure. The way that divides

complex missions into different parts makes the system reparable and reliable; it is

not only useful for single soft upgrade but also for the upgrade of the whole

水轮机调节系统是一个本质非线性、时变、非 小相位系统,其控制性能指标与

稳定性一直是人们所关注的问题。随着控制技术的发展,水轮机调速系统的控制规律

也在不断地发展和完善。虽然近年来,自适应控制,变结构时变参数自完善控制,模

型参考多变量 优控制等基于现代控制理论的控制模型和控制方法也被提出并进行

了大量的理论研究,但由于水轮机调速系统是一个时变且存在随机扰动而又相对快速

的控制系统,目前,仍然广泛采用 PID 控制规律。而常规 PID 控制系统需要精确的数

学模型,一般只适用于线性系统,常规的 PID 控制很难得让其具有良好的动态品质。

The hudraulic turbine regulating system whose control index and stability has

attracted more attention of the public is a non-linear, changable and non-min phase

system. The controlling rules of turbine speed regulating system has been

perfecting with the development of controlling technology. Although in recently

years, the study of controlling modes and methods based on modern controlling

system (e.g. Automatic controlling, parameter’s self- perfection when changing

the structure, multi-quantity and best-controlling of modular reference) has begun,

PID controlling principles have also wildely used presently since the turbine

regulating system is a system with variation and compared quick-speed. However,

Page 22: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

21

the common PID controlling system needed precise mathematical modes is only

suitable for linearity system whose dynamic quality can not be secured with

common PID.

在这里,我们采用了一种新型 PID 控制器——基本型逻辑控制器,俗称九点控制

器,根据偏差与偏差变化率将实际运行状况抽象成九个工况点(强加、稍加、弱加、微

加、保持、微减、弱减、稍减、强减 9 种工况),从而给出相应的控制策略进行有效的

控制。其基本思想是控制器根据控制系统的实际运行模式特征,不断地改变或调整控制

决策,以便使控制器本身的控制规律适应于控制系统的需要,获得良好的响应性能。由

于这种控制器产生的控制作用只取决于被控对象的运行工况,因而对相当广泛的被控

对象具有适应性。由于不同的工况点对应不同控制策略,因此又具有适应式变参数变结

构非线性控制的特点。控制算法简单,易于工程应用的实现。对于稳定的控制对象,能

同时得到良好的静态品质和动态品质,即使对于不稳定的被控对象也有镇定调控作用。

因此基本型逻辑控制器适合应用于水轮机调速系统,以改善其特性。

Herein, we adopt a new PID controller ---basic and logical controller (also

called nine-point controller) which can be abstracted into nine operating points

(strong plus, weak plus, plus, little plus, remaining, weak minus, miuns and heavly

minus) to control aoocrding to the tolerance and its changing rate. Its fundamental

principle is to continually change or adjust controlling methods in order to make the

controlling rules of controller itself satisfy the system requests for good capacity

according to the features of controlling system operating modes. As the controller

works only influenced by the operating conditions of controlled objects, it is largely

used by controlled objects. However, different operating points with different

contolling methods, the new controller can change parameter, structure and control

with non-linearity. Simple calculating in controlling makes its engine application

come true. The stable controlled objects can simultaneaously obtain good static

and dynamic qualities, even though it has effects on unstable ones, thus basic and

logical controller can apply to water turbine speed regulating system to improve

performance.

该型调速器具有频率调节、开度调节和功率调节三种控制模式,根据需要可选择

不同的控制模式。这种切换,一是通过操作终端上的触摸键或二次回路接点来完成,

Page 23: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

22

二是通过数字通信接口来完成。采用频率调节模式时,又分为跟踪频给和跟踪网频方

式。跟踪网频方式运行时可实现机组频率跟踪电网频率,这样可以保证机组频率与电

网频率相一致,便于并网。当采用功率调节模式时,PI 环节按功率偏差进行调节,实

现机组有功功率恒定。这种方式运行可以很容易实现全厂 AGC(自动发电控制)。对

于功率给定,它一方面作用于 PI 环节,另一方面通过开环控制直接作用于输出,提

高了功率增减速度。功率给定为数字量,适用于上位计算机给定。

电气开限环节是针对 PID 运算结果进行限制,限制输出不超过电气开限。

Governor has frequency regulation, opening regulation and power regulation

three kinds of control modes, which can be chosen according to the practical

needs. The change of them can be done through the touch key on terminal or

secondary circuit contact, or through the digital communication interface.

Frequency regulating mode has tracing frequency and network frequency. The

mode of frequency regulating insures that unit frequency conforms to net frequency

for synchronous operation. Power regulating mode utilizes PI link to regulate units

according to the power difference for the constant output power. It is quite easy to

realize the whole plant AGC (Automatic Generation Control) when units operating

in this mode. Power setter is utilized to regulate units by PI link and, meanwhile,

directly output by open-loop control to improve the increasing and decreasing

speed. The power setter could be digital signal, which is set by upper computers .

Electric limiter link limits the output of PID to make sure output not exceeding

Electric limiter .

数字放大器将 PLC 输出与接力器反馈采集量进行比较放大后输出。对接力器的

控制采用双闭环结构,除接力器反馈外,还有一个电机反馈或比例伺服阀反馈,以控

制无油电转或比例缸精确定位,补偿反向间隙、各种机械误差和磨损等。

Digital amplifier compares the PLC output with the data sampled by

servomotor feedback, amplifies and output. Dual closed loop structure is adopted

for the control of servomotor, besides servomotor feedback, there is a motor

feedback or Proportion servo valve feedback for the control of oil-free

electro-hydraulic transduceror or Proportion cylinder’s accurate loacting, the

compensation of various kinds of mechanical errors and abrasion etc.

故障保护等功能。Even if error occurs at operation terminal, PLC performs the

control functions, for instance, start, stop, load increase/decrease, breakdown

protection, etc

8.当交、直流电源同时断电时,机械液压系统自动复中零位,保持接力器当前

位置不变。When A/C, D/C breaks simultaneaously, mechanical hydraulic system

will become zero automatically and no change to servometer.

测频环节原理图

Schematic diagram of the frequency measurement

如图所示,测频环节采用先进的数字式脉冲测频方式。取至发电机出口 PT 的机

频信号以及取至电网 PT 的网频信号,经隔离、整形成同频率的方波信号后,直接送

至单片机的引脚,由单片机纪录两个上升沿之间经过的基准脉冲个数,即可测得方波

信号的周期,从而得到频率。由以上频率测量的原理可知:数字式脉冲测频方式的精

度取决于基准脉冲的频率,基准脉冲的频率越高,对同一频率测的数据精度就越高。

As shown in above figure, frequency measured by advanced digital impulse.

The unit frequency signals from motor exit PT and net frequency signals from grid

PT change into square-iscillation signals after isolating and plastic making, then

directly send to the pin single-chip which will record the number of benchimpulse

between the two rising ends, finally the frequency is gained with the

square-iscillation signals period. Following conclusion can be made above

principles: the accuracy of digital impulse frequency measurement depends on

benchimpulse frequency; that is to say, the higher the benchimpulse frequency, the

more accurate of the data in the same frequency measurement.

② 频率测量环节特点 Frequency measurement characters:

Ⅰ、数据方式独特:将 PLC 应用于水轮机调速器以来,一直由于 PLC 的高速计

数模块 高计数频率仅能记到 500K,远远不能达到水轮机微机调速器对测频精度

(>750K)的要求。

Unique digital method: since PLC has been used in turbine Governor, the

frequemcy measurement accuracy required by turbine microcomputer Governor

can not be reach for the max counting frequencyof the PLC high speed counting

Page 63: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

62

module is only 500k.

如何完成 PLC 对频率信号的测量,一直是困扰着国内以 PLC 作为调节器的生产

厂家。少部分厂家牺牲了测量精度,以 PLC 的高速计数器进行本体频率测量;大多

则采用一个单片机完成机、网频的测量,再将二者的差值,以 16Bit 带符号数据的形

式,通过一个 16 点的 I/O 输入模块,送入 PLC 总线。这种测量方式存在以下问题

①增加了系统环节,降低了可靠性。

②由于单片机测频模块与 PLC 的 16 点 I/O 输入模块各自工作于不同的时序,

16Bit 的差值数据在传送时,容易出现时序配合不对,导致 PLC 读入错误的值,引入

了人为干扰信号。

PLC③ 读入的是机、网频的差值信号,而不是机、网频的单独准确值,在空载状

态下,PLC 无法准确的测得系统的频率,也就无法应用彩色触摸屏方式显示准确的系

统频率。

我公司采用总线方式,直接将数据通过总线送至 PLC,彻底解决了长期困扰可编

程调速器的关键点。

Manufacturers who own PLC the Governor have been confused with how to

measure frequency signals by PLC for a long time. Few make frequency

measurement by PLC high speed counter through ignoring measrement accuracy;

while most manufacturers adopt one single-chip to measure unit and net frequency

first, then take difference between them, which finally is sent to PLC bus by a 16

points I/O input module in the 16Bit with data. However, problems appear with the

latter method:

① Increasing system circles and decreasing reliablity

② Owing to different time sequence between of single-chip frequency

measurement modules and PLC 16 points I/O input modules, when

sending 16Bit different data, it is easy to wrongly match time sequence

which will lead PLC to reading wrong values and interrupting signals.

Due to what PLC reads are different signals of unit and net frequency

instead of their individual values, under no-load condition, PLC can not

measure accurately system frequency which thus can not de displayed

by colorful touch screen.

Page 64: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

63

③ STRONG adopts bus way , sending data to PLC by bus directly to

resolve the key point that puzzled the programmable Governor in the

long term completely .

Ⅱ、测量精度高:基准脉冲由单片机晶振产生,基准脉冲为 6MHz,对于 50Hz

的频率信号测量精度为 1/120000。远远超出标准的规定,这是任何一种 PLC 利用高

速计数方式实现本体测频达不到的。

High measurement accuracy: benchimpluse caused by single-chip Crystal

oscillator is 6MHz; the measurement accuracy of 50Hz frequency signals is

1/120000, which is far beyond the standard and no PLC by high speed counting

meets with.

Ⅲ、集成度高、抗干扰性能力强:该单片机采用超大规模的 CHMOS 工艺制造,

内部集成 WatchDog,抗干扰性能极强;且内部集成了 Flash Ram,进一步减少了外

部硬件构成,增强了可靠性和抗干扰能力,并具有“软升级”能力。

High integral and strong anti-jamming: the single-chip is made by large-

当高的控制调整精度,满足用户安全可靠的实际需要,从而达到高品质的调速要求。

The WT and WZT mechanical hydraulic system controls motor driver with

high accuracy through PLC Governor system, driving ball-screw and self-righting

pinpoint position device, making pilot valve and main distributing valve move and

output a some flux hydraulic pressure oil according to the rate in order to drive

performable component to control rotate speed and load of hudraulic turbine to the

extent with great high adjustment precision. Hence, we can meet user reliable

actual request and get to the demand of high quality product.

机械液压控制系统组成及原理图如下:

The theory diagram & system composition for mechanical hydraulic control system

is as follows:

PLC 调速器控制系统根据输入电信号和反馈,经 PID 运算、放大后,输出数字

信号给无油电液转换器,无油电液转换器再输出成比例的位移,经引导阀和主配压阀

液压放大而形成巨大的操作力,控制水轮机的导叶开度 α和桨叶转角 φ,实现水轮发

电机组的调速和负荷控制。

Page 80: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

79

The control system of PLC Governor works on PID operation and magnifies it

according to input electrical signal and feedback, then, outputs digital signal to

oil-free electro hydraulic transducer, which also outputs proportion displacement

and an immense operating force, which operates the openingα of the guide vane,

and angelφof paddle blade to realize speed adjusting and load control of turbine

motor units.

电液随动系统具有二级液压放大,第一级是引导阀和辅助接力器,第二级是主配

压阀和主接力器。

The electro-hydraulic servomechanism has 2-stage system for hydraulic

pressure magnifying. The first stage is pilot valve and auxiliary servomotor, and of

the second is main distributing valve and main servomotor.

PLC 调速器控制系统将输出信号与接力位置反馈信号进行比较放大后,输出数字

信号驱动电机带动滚珠丝杆及自动复中装置,产生与输出信号成比例的位移,因该装

置与引导阀直接连接,所以此位移使引导阀产生相同的位移行程,并通过辅助接力器

使主配压阀也产生相应的位移,同时向主接力器配油使之产生位移,直到主接力器位

置信号与输出的数字信号相等为止。

After comparing and magnifying the feedback signal of the servomotor position

and output signal, the PLC controlling system output signal to make motor run

ball-screw and self-righting pinpoint position device in order to produce

displacement in proportion with output signal, which can let the pilot valve move the

same displacement because of direct connection with pilot valve. Accordingly, the

main distributing valve form the completely uniform displacement through auxiliary

servomotor, at the same time, providing oil to the main servomotor and make it

displacement till the signal of main servomotor is equal to the output digital signal.

auxiliary servomotor, main distributing valve quickly revert mid position and make

the main servomotor initialization. It costs less oil in static state than any conditions

together with reliable performance. It’s very convenient to adjust and maintain.

There is no traditional theittling orifice of electro-hydraulic servo valve, it has high

reliability and oil pollution problems don’t exist in it, meanwhile, avoid the system

uncertainty because of too much procedure.

(2)采用比例伺服阀的机械液压系统 Proportional servo valve

输出电压控制比例伺服阀或通过输出不同宽度的脉冲信号控制开、关机阀实现闭

环调节。

Output voltage controls proportional servo valve or via different wide impusling

signal to control open/close ball valve to realize loop close regulation.

比例伺服阀(开、关机球阀)使比例缸上腔接通压力油或排油与比例缸活塞形成

流量差[当比例伺服阀(开机阀)向比例缸上腔注入压力油时,比例缸活塞通排油,

只不过比例缸活塞的流量较小;比例伺服阀(关机球阀)让比例缸上腔接通排油时,

比例缸活塞通压力油,只不过比例缸活塞的流量也较小],使主配阀活塞上、下移动

而实现开、关机,流量差的大小决定主配压阀活塞的行程。

proportional servo valve (open/close ball valve ) makes upper reservair of

proportional cylinder connect with pressure oil or discharged oil to form flow

difference with proportional cylinder piston. When propotional servo valve(open

ball valve) injects pressure oil into the upper reservair of proportional cylinder,

proportioanl cylinder piston connects discharging oil, but its flow is smaller thant

that of proportional piston; When propotional servo valve (close ball

valve )connects with upper reservair of proportional cylinder, proportional cylinder

piston connects with pressure oil, but its flow is smaller thant that of proportional

piston; to make main distributing valve piston move up and down to realize

open/close. The flow difference depends on the stroke of main distributing valve

piston.

在任何情况下,运行人员都可以现场手动切换工况切换阀到数字阀工况,再手动

操作开、关机阀,实现手动操作。

Under any condition, the operator can change work conditions manually and

Page 82: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

81

change valve into digital valve conditiona manually, and then operate manually for

ball valve open/close to finally realize manual operation.

(3)W(Z)T 系列械液压系统可以通过电信号或者运行人员现场手动操作紧急停机电

磁阀,使辅助接力器上腔直接排油,实现紧急停机。

The system, via electric signal or site operation to emergency stop magnetic valve

by the operator, to make the upper reservair of auxiloary servomotor discharge oil

directly to finally realize emergency stop.

为提高可靠性,系统取消了机械反馈杆件和反馈钢丝绳,对厂房布置极为有利。

For reliability purpose, mechanic feedbanck members and feedbanck wirngs

位块,一对复中上弹簧,下弹簧直接利用引导阀弹簧,其复中上弹簧的预压力 2 倍于

复中下弹簧(引导阀中的)预压力,而上下操作引导阀阀芯的力又大小相同。

The characteristic of which is that it has one locating piece, a pair of

auto-revert up-spring. The down-spring directly takes advantage of pilot valve

spring, of which the up-spring’s pre-stressing is 2 times than that of the

down-spring (in pilot valve), however, the force value existing in valve core of

up-down operating guide valve is equal.

复中上弹簧将定位块压向限定位置,而复中下弹簧又使引导阀阀芯通过调速杆连

接套压在定位块上,形成上大、下小的复中力(上复中力已为定位块限止,没有外力

是不会上下动作,而下复中力也推不动上定位套),所以连接套向上运动时,引导阀

在弹簧的作用下,随之上移;连接套向下移动时引导阀在旋转力矩的作用下,向下移

动。由于大导程滚珠螺旋副能逆向转动,在复中力的作用下,使连接套复中至限定位

置,精确定位,此时只要调整引导阀的中位(即零位),使主接力器在 5 分钟内位移

量小于 1mm,即是自动零位和手动零位。

The auto-revert up-spring presses the locating piece to the limited space.

While the auto-revert down-spring let the valve core of pilot valve cover the locating

piece through Governor rod, forming the big revert force upside and the little

83

downside (the upside force doesn’t act up and down being limited by locating piece,

meanwhile, the downside force can’t move the top position sleeve.), so the pilot

valve shifts upside following the spring force when bond sleeve moving upwards;

the pilot valve shifts downwards in the action of rotary moment when bond sleeve

moving downwards. As the long-lead ball screw-pair could rotate conversely, which

confine the bond sleeve to a fixing place through revert force, now you can only

adjust the nil-position of pilot valve and make the main servo’s displacement less

than 1 mm within 5 minutes, namely, that is auto-nil position and manual nil

position.

当电机退出工作时,用双手转动手轮,能模拟电机操作阀芯,松开手轮,在复中

装置作用下,阀芯迅速回到中位。

When motor is stopped, running the hand-wheel manually could simulate the

operating core valve of motor. As you let the hand-wheel alone the valve core

swiftly goes back the nil position through reverting device.

The upper-oil cavity is always switching on pressure oil ,when guiding the pilot

valve to move a distance upward. While the lower oil cavity of assist servo is

connected with pressure, the useful area of which is greater than that of the upper

cavity of assist servo, so the pressure oil makes the piston of assist servo transfer

reservoir sweep, as upper cavity is always connected with pressure oil, the assist

servo moves down a single distance till the piston of pilot valve is again closed off

the oil outlet so the assist servo could be stabilized at another balance position. As

a result, the piston of assist servo is always following the piston of pilot valve.

Being manufactured as a whole of piston of assist servo and main gate valve, the

piston of main gate valve is also following piston of pilot valve.

当主配压阀活塞在中位向上移动时,主接力器开启侧通压力油,关闭侧通排油,

主接力器活塞向开机方向运动。反之,主接力器活塞向关机方向运动。

The pressure oil on the open side of main servomotor is switched on,

meanwhile on the close side of which reservoir sweep is working, the piston of

main servomotor moves towards to the starting when piston of main gate valve

shifts upwards from zero position, Whereas, which shifts towards to the tailoff.

9.2.4 紧急停机电磁阀 Emergency Stop solenoid valve

机组正常运行时,紧急停机电磁阀处于接通引导阀压力油、辅助接力器下腔与排

油的油路通道被切断的位置,故引导阀与辅助接力器正常运行。

When normally working, solenoid valve of emergency shutoff device is in a

position where puts through pressure oil of pilot valve and cut off the oilway

between the bottom cavity of assist servomotor and reservoir sweep. Therefore,

the pilot valve and assist servomotor run in a course of nature.

There are two swift-throwback dross filters in the fuel strainer when normally

working. The oil pressure meter is set behind the dross filter and the oil pressure

value can be observed through that meter.

9.2.7 分段关闭装置(选配) Closing Device with serval rates(optional)

分段关闭装置分为机械式分段和电磁阀式分段,以机械分段为例说明如下:

The step closure device can be devided into mechanical and solenoid valve

type.Taking machanical step-closure for example:

分段关闭装置由分段阀、单向阀和凸轮等组成。凸轮固定在接力器传动机构回复

转轴上,在分段之前,分段阀下部滚轮不和凸轮接触,当接力器关闭到回复转轴上的

凸轮顶着滚轮,带动先导阀上升时,分段阀的节滚活塞下腔即瞬时接通压力油,节流

注意/Warning 巡视时,应注意观察其压力值,当压力值低于油压罐压力时,检查滤

网是否堵塞。否则会造成接力器不能随动。

When perambulating, you should look into the pressure vaule ,If it is

below the oil tank pressure ,to check out the filter if occlude, ortherwise

the servomotor can not move.

活塞迅速上升至其上方调整螺钉整定的位置,于是接力器在关闭过程中开始分段进行

慢关机。

The sectionalizing shutoff device is made up of section valve、inverted valve、

cam and so on. The cam is fixed on the return-axis of swivel that is attached to the

drive gear of servomotor. Before sectionalized the contact roller on the bottom of

section valve doesn’t touch with the cam. When servomotor is in a close point

where the contact roller is propped up by the cam of reverting axis, making the pilot

valve ascending. Here the bottom cavity subjected to the rolling piston of

subsection valve instantaneously is put through with pressure oil. Throttle piston

swiftly moves upwards to the position of adjust screw, which have the servomotor

shutoff step by step during the course of the tailoff.

调整分段阀上方的调整螺钉,可以改变节流活塞与阀体之间的节流面积,从而可

以改变分段后的慢慢关机速度。

The adjust screw on the top of adjust subsection valve could change throttle

areas between throttle piston and valve body, thus slow and stepped shutdown

speed can be changed

转动凸轮,改变它和回复转轴的相对位置,就可以改变分段关闭的拐点位置。

The step –closure turning position can be changed by rotating cam and

changing its postion with returned shaft.

单向阀可以保证导叶接力器能从全关位置快速开启到分段拐点而不受分段阀节

流影响。

One-way valve secures the guide vane servomoter starting to step-by -step

turning point from full-closed position without throttling inflence from step-by-step

vlave.

该分段关闭装置全部采用刚性联连,可以精确地进行调整,一经调妥后,分段拐

点及分段后速度不会再变化,安全可靠。由于该分段关闭装置靠近接力器,所以对装

有事故配压阀的水电站,同样能起到 终分段的作用。无需在事故配压阀之后再装分

段关闭装置。

This device adopts rigid connection with accurate adjustment. There is no

speed change and reliable in step-by step turnings, once adjusted well. Due to the

90

device is closed to servometer, it also can make final subsection at eleco-hydraulic

stations with accidental voltage valves (no need to intall step-by step closure

device again).

分段关闭的先导控制还可以采用电磁换向阀来控制。当接力器关到其分段关闭的

拐点时,电气控制信号控制电磁换向阀动作,从而控制分段主阀实现分段。也可以采

用手动直接操作电磁换向阀。

Solenoid valve is as the guide control of this device .when the servomotor

close to the inflection point ,electrical control signal control the solenoid to move to

realize fragments. We can also operate solenoid directly by manual.

9.2.8 事故配压阀(选配) Emergency distributing valve(optional)

SGP 集成式事故配压阀是一种二位六通型换向阀,用于水电站水轮发电机组

的过速保护系统中,当机组转速过高,调速器关闭导水机构操作失灵时,SGP 集成

事故配压阀接受过速保护信号动作,其阀芯在差压作用下换向,将调速器切除,油压

装置上的压力油直接操作导叶接力器,实现紧急关闭导水机构,防止机组过速,为水

轮发电机组的正常运行提供安全可靠的保护。

As a six-way directional valve, SGP integrated emergency distributing valve is used

in hydro turbine over-speed protection. When the unit speed is over high and

governor closing pilot organization operation is out of service, SGP integrated

emergency distributing valve acts after receiving the over-speed signal. Valve core

will change its direction with the function of pressure difference, cut of the governor,

presssure oil from its device will operate guide vane servomotor directly to realize

emergency stop of pilot organization and protect unit from over speed and protect

turbine units working under normal and reliable conditions,

本产品通过优化设计,将传统的过速限制器上的电磁配压阀、油阀、事故配压

阀集成于一体,体积更小、动作更可靠;它采用液压缓冲装置克服了原过速限制器在

动作时的轰鸣声,动作平稳,使用寿命更长;安装方便,布置场地小。

The product has been optimized and integrated magnetic distributing valve, oil

valve, emergency distributing valve on the over-speed limiter into one, which is with

smal volume and more reliable actions. The hydraulic cushion device has

Page 92: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

91

overcome the roar sound from the old limiter. It acts stably, is long lifetime, easy to

be isntalled with little place.

将传统过速限制器上电磁配压阀、油阀、事故配压阀集成于一体,集成化

程度高、体积小、重量轻、占用场地小、安装方便

Integrated magnetic distributing valve, oil valve, emergency distributing

valve on the over-speed limiter into one, which which is with smal

volume light, and easy to be isntalled with little place..

采用液压缓冲装置,无振动声,使用寿命长。

The hydraulic cushion device is non vibration sound and long lifetime.

当调速器发生故障至使机组转速过高,调速器无法完成通过接力器把导叶关闭回

来,此时监控系统发至事故停机信号至事故配压阀的电磁换向阀,事故配压阀右边的

活塞腔就接通压力油,因右边的活塞面积比左边的大,所以活塞向左动作,此时活塞

把主配压阀的开、关机腔的油源切除掉,把导叶接力器的开、关机腔与回油、压力油

接通;即系统压力油与接力器的关腔接通,接力器开腔与回油箱接通,从而实现了事

故停机,避免机组发生飞逸事故。

When the governor malfunctional makes unit speed over high, the guide vane can

not be closed via servomotor by the governor; the piston reservair at the right of

emergency distributing valve is to connect pressure oil, since the area at right is

larger than that of the left, when the piston moves left, the piston will cut off the oil

supply of both close and open reservair of the main distributing valve, and connect

close and open reservair of the guide vane with return oil and pressure oil. Namely,

the system pressure oil is to connect with the close reservair of servomotor and

open reservair of servomotor with oil return tank. This is the way of emergency

stop,which avoid unit runaway.

通过调节事故配压阀右边的螺杆,可以调整活塞与阀体开口大小,限制其流量

来实现事故配压阀的动作时间。

By the screw bar at the right of emergency distributing valve, opening between

piston and valve body can be adjusted to limit its flow to achieve required action

time of the emergency distributing valve.

device the null adjustment is actually to regulate the mesoposition of pilot valve.

Firstly, loosen screw nut and regulate the joiningup lower screw stem so that the

piston of pilot valve moves up and down relative to the gland. The adjustment

working lasts till the main servomotor could stabilize in any place (rotate the

handwheel of ball spiral auto-reversion device slowly, which makes the servomotor

open and close). It is impossible to have the servomotor in a completely stable

place because of open loop. It is generally allowable for servomotor to have

deviation less than 1 mm within 5 minutes. Then merge the nut tightly.

(见 HYZ 型、YZ 型油压装置液压系统图)(please refer to hydraulic system diagram

of HYZ, YZ oil pressure device):

油压装置和其用油的设备构成了一个封闭的循环油路。回油箱<15>内的清洁油经

过油泵<17>的吸油管被油泵吸入并增压输送至组合阀<10>内的止回阀腔内,随着输

油量的增加,压力逐渐升高,直至超过止回阀活塞上腔的压力,使止回阀打开,压力

油通过止回阀及压力罐根部截至阀进入到压力罐内。油泵是由电动机<18>通过联轴器

拖动的。

The oil presure device forms a close loop of oil circulation together with oil

comsumption. Oil from oil return tank(15), through the absorption tube of oil

pump(17), will be absorbed by pump and increase pressure and then send to

check valve in the combine valve(10). With the increasing of pressure gradually,

pressure increases gradually and the check valve opens when the pressure

exceeds that of upper reservair of check valve piston. Oil will enter the tank through

the check valve and cut-off valve at the bottom of pressure tank. Oil pump is driven

by motor(18) through coupling.

为了保证油压装置工作的可靠性,每台油压装置一般都设有 2 台油泵,一台为工

作油泵,另一台则为备用油泵,两者可定期互相切换使用。在特殊的情况下,即当工

作油泵工作时,油压仍继续下降直至备用油泵启动的压力,备用油泵启动。两台油泵

也可同时做短时间的并联运行。油泵可以是螺杆泵,也可以是齿轮泵。

Page 101: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

In order to keep reliablity, each oil pressure device equips with 2 oil pump: one for

work and the other backup. Under special condition, when work pump is at work,

the pressire will continue to drop unitil achieving presure for backup pump startup,

and then backup pump starts. Two pumps can run at the same time shortly. Either

screw pump or gear pump can be used.

每台油泵的前部都设有组合阀。组合阀是集止回、卸载、安全、卸荷(溢流)等

功能于一体,对油泵、电机和压力罐起保护作用和稳定压力罐的油压作用的装置。止

回阀保证了当油泵停止工作后,不使压力罐内的压力油通过油泵途径被泄掉。卸载阀

可使油泵出口至止回阀间油路在油泵停止工作后迅速泄掉压力,使工作油泵重新启动

时,电机是空载启动,并可以延时,使电机有一个良好的启动环境,不但可以节约电

能,也对电机起了一个保护作用。安全阀的设置是对压力罐起保护作用的一道安全措

施。当控制油泵运行的二次回路出现故障,而油泵运行又使压力罐内的油压超过了油

压工作范围的上限而不能停止时,罐内油压继续上升至安全阀动作整定值时,安全阀

动作,使油泵输出的压力油通过安全阀又返回到回油箱内,不至使压力罐油压继续上

升,从而保证了压力罐的安全。油压装置的油泵一般都设置的是断续工作制,如工作

需要设置为连续工作制时,卸荷(溢流)阀可起稳压的作用。

Each front of oil pump has been equipped with combined valve which has

integrated functions of check valve, load-off valve, safety valve, overflow valve etc. ,

protects oil pump, motor, pressure tank, keep tank presure stable. When the oil

pump stops, check valve can prevent the pressure oil passing pump from

discharging. Load-off load can drop pressure in the tube between the pump oulet

and check valve, make motor at no-load condition if the pump restarts again; and if

delaying, it can make motor at good atomosphere: not only saving engergy but

also protecting the motor. Safety valve is to protect pressure tank.when failure

happens on the second circuit of the oil pump, pressure in the tank exceeding the

limit which makes pump stops, the pressure in the tank keeps increasing until

safety valve acts, which makes the oil returns to oil return tank and prevents oil

pressure from increasing to finaly realize the pressure tank safety. The oil pump is

usually set by incontinuous work ssytem, if continous system needed, overflow

101

valve can keep pressure stable.

压力罐在正常情况下,上部(压力罐总容积的 1/2~2/3)充满了压缩空气,下部为

介质油。压缩空气的补充、泄放可通过自动补气装置<1> 自动进行,也可以通过装在

压力罐进气孔根部的补气放气阀来进行手动操作。(用户在使用前请详细阅读自动补气

装置生产厂家的《使用说明书》)。

Under normal condition, the upper part (1/2~2/3 of total volume) of pressure

tank is filled with compressed air, and the lower part is media oil. The

complementary or discharging of the air can be realized either by automatic

replenish device(1) or manual replenish/discharging valve at the bottom of tank air

inlet.(Clients should read “the user manual” of the automatic air admission

equipment manufacturer in details before putting to use.)

压力罐也可选用囊式蓄能器。囊式蓄能器内的高压氮气在出厂前已充足,一般无

需再充气,特殊情况下可用专用的充氮工具(见下图)充入。

Bladder accumulator also can be chosen as pressure tank . high pressure nitrogen gas in the bladder accumulator has already fully inflated, so, generally speaking, no more inflation is needed. A special nitrogen inflating tool (please see the fig. below) can be used for air inflation at special situation.

充气时,先将囊式蓄能器顶部旋下,把充氮工具螺口 1旋上,然后将充氮工具螺

帽 2与高压氮气瓶口相联。顺时针旋转充氮工具的旋阀 3顶开蓄能器气门芯,然后打

102

开氮气瓶的阀门充气。观察压力表 4上的压力值,当压力值在氮气瓶的阀门关闭后达

到额定值时,即可停止充气。逆时针旋转充氮工具的旋阀 3至上止点,拆下充氮工具,

就完成了充氮过程。

While inflating, firstly screwing off the bladder accumulator head cover and

screwing on Lo 1 of the nitrogen inflating tool, then connecting nut 2 of the nitrogen

inflating tool with the mouth of high pressure nitrogen gas flask. Clockwise rotating

the rotary valve 3 of nitrogen inflating tool to open the accumulator valve inside,

then beginning to inflate after opening the valve lead of nitrogen flask. Observe the

pressure valve of manometer 4. Inflation finishes if the value reaches rated one

after the close of valve lead of the nitrogen flask. Anticlockwise rotating the rotary

valve 3 of nitrogen inflating tool to the end, removing the nitrogen inflating tool,

then the inflation finishes.

为了反映压力罐中油位的高低(蓄能器无),根据业主的要求而装设了类型不同的

油位计<2>,使用较多的是磁浮子翻柱型的液位计,从表板上可直接观察到压力罐内

的油位高低,又可对液位超越上下限时进行报警。如果配置了传感器,并可在油位的

整定范围内发出 4~20mA 或 0~10V 的模拟量的连续信号,供计算机监控进行采样。

103

meters(2) can be selected in the light of clients’ requirement. The mostly selected

one is the magnetic liquid level meter which can easy show the lelel straightly, and

alarm when it is above or lower than corresponding upper or loawer limit. If a

transducer equipped, it also can send continous signal of simulation with the range

of 4~20mA or 0~10V for the sampling of computer monitoring.

在压力罐上,可根据用户的要求,配置型号各异的压力传感器<1>、压力开关<2>

和普通压力表<3>,可分别用于计算机监控系统的采样、工作油泵、备用油泵的启动

和停止的控制,事故低油压信号的发讯,自动补气、自动放气的控制以及电站运行人

员的现场目视等。这些反映压力相关参数的表计,一般都安装在与压力罐相连接的表

架上,每个表架上都设有控制油路通断的阀门,以保证这些表计能够更换或维修。

According to client’s requirement, different pressure transducer(1), pressure

switchgear(2) and common pressure meter (3), which can be used for computer

monitoring sampleing, startup & shutdown of work pumpand backup oil pump ,

emergency low presure signal sending, control of automatic air replenishing, and

discharging and visual observation of site operators correspondingly, can be

equipped on the pressure tank. Generally, they are installed on the frame

connecting with pressure tank. Each frame has a valve to control oil tube breaking

to ensure that all meters can be replaced or repaired

在压力罐体上开有不同通径的孔口,并配有相应的阀门。它们的功用分别是:进油

口阀门二只,一般是角式截止阀,用在油泵至压力罐的通路上;放油阀一只,一般也

是角式截止阀,其通径往往和进油阀一致(有的也可能比进油阀小一个规格),是为

压力罐放油所设置,通常在油压装置油泵试验,组合阀各参数值整定及压力罐手动补

气时使用;主压力油供油截止阀一只,一般为直通式阀门;辅助油源截止阀一只,一

般也是直通式阀门或盲板盖。油源通过主压力油供油阀门或辅助油源阀门引出,通过

液压系统的各类控制元件及管路,作用到执行元件上,使执行元件作功,进行能量交

换后的介质油回到油压装置回油箱的污油区,经滤油网<19>过滤后进入净油区,再经

油泵吸入,加压送往压力罐,如此往复循环。

On the pressure body, there are holes with different diameters, equipping with

corresponding valve. The functions are: two inlet valves which usually are angel

type cut-off valve used on the tube between oil pump and pressure tankt; on oil

discharging valve which which usually is angel type cut-off valve and same

diameter as that of inlet valve(sometimes little smaller than that of inlet valve) used

for pressure tank discharging and used during oil pump test, combine valve

parameters setting and manual air replenishing; on check valve for main pressure

oil supply, which is usually once through valve; one check valve for auxiliary

pressure oil supply, which is usually once through valve or blind plate cover. The oil

supply is educed through main or auxiliary pressure oil supply valve, through

different control components and tube of hydraulic system, acts on execution

components to make them work. Media oil after this energy exchange returns to

dirty oil area of the oil return tank and comes into the clean area after filter (19).

And then it is sent to pressure tank after increasing pressure and oil pump

absorption. The pressure oil works in such circulation way.

设有自动补气装置的油压装置,一般都设有空气安全阀,其位置在压力罐的顶部,

是在补气状态失控时,对压力罐起保护作用的装置,其整定值比油泵安全阀要稍高

2~4% 。

As for the pressure device without automatic air replenish device, it is often

euqipped with air safety valve installed at the top of the tank. Under out control of

replenish status, it can protect pressure tank and its set value is 2~4% higher than

that of safety valve.

往往由于空气的潮湿和水系统的渗漏,在水电站的油系统中被混入一部分水份,

这部分水份被带入液压系统的各类元件中,将造成金属零件的锈蚀,恶化了元件的技

术性能。介质油中被混入水后,易造成油质乳化,使油变质。为检测回油箱中贮油的

含水率,往往在回油箱中装设油混水信号装置。当油箱中的油,含水量超过报警设定

值时,会提醒工作人员及时进行检察和处理。

Sometimes due to air moisture or leakage from water system, part water has been

mixed in the oil system in the hydro power station. This water has been distributed

to different components of hydraulic system to make metal part rust and erode,

which is harmful of technical performance. Oil mixing with water is easy to make

oil emulsification and metamorphose. To test the water content in the oil return tanl,

oil and water mixture signal device is always equiped in the oil return tank. When

10.4.4.3 结构特点 structure features

本阀由两个插装元件和三个先导阀所组成,它包含了逆止阀、卸载阀、安全阀和

卸荷阀的功能。在先导阀 YV1 YV2 YV3 控制下,主阀 CV1 完成开启和关闭的动作。

CV2为逆止阀。由于组合阀系统采用先导控制,因此当组合阀工作时无噪音、无震动、

运行平稳。

组合阀设有三个油口,组合阀压力油进口 P、组合阀出油口 P1与组合阀回油口 T,

P 口与油泵出口相连,出油口 P1与压力罐进口相通,回油口 T 与油箱相连。

为:

CV1-主阀

CV2-逆止阀

The valve is composed of two plug-in components and three pilot valves, which will

perform as the backwards valve, shutoff valve, security valve and load-shed valve.

In the control of pilot valves (YV1 YV2 YV3), the mainly valve (CV1) is responsible

Page 115: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

114

for the start and close. The CV2 works as backwards valve. The combination valve

system adopts the pilot control, so there is no noise or no oscillation when working.

There are three holes of the combination valve, first is P for the entrance of

pressured oil,the second is P1 for the exit of the compressed oil, and the last is T

for the return of the oil. P is connected with the exit of the oil pump, and P1 has

connection with the entrance of the pressure tank, while T is linked with the oil tank.

In the figure of the liquid pressure system, the two plug-in components(one is the

mainly valve and the other is the backwards valve)and three pilot valve is

represented as

CV1-mainly valve

CV2-the backwards valve

YV1-pilot control valve for shutoff

YV2-pilot control valve for security

10.4.4.4 工作原理 Working principle (参见组合阀系统图)(please refer to the system diagram of combined valve)

10.4.4.4.1 卸载阀 Shut-off Valve

由于大功率油泵的电动机惯量大,所以从启动到稳定状态需要一定的时间。如果

在螺杆泵达到额定流量之前带上负载,则对油泵、液压系统均十分不利。采用卸载阀

可以使油泵启动时处于卸荷状态,直到电动机转速达到一定值后,油泵才能输出额定

工作压力和流量的压力油。

卸载阀是由卸载先导 YV1与主阀 CV1组成。

油泵启动时,由于 P1 的作用,逆止阀 CV2 处于关闭状态。卸载阀在弹簧作用下

处于开通状态。主阀 CV1控制腔无压力油,油泵压力油流过 CV1主油口回到回油箱。

随着电动机转速增加,P 口压力逐渐上升,控制油到达卸载阀上腔并克服弹簧力使活

塞移动,关闭卸载阀。此时压力油进入 CV1控制腔,使 CV1关闭。从而 P 口压力达

到额定压力值,单向阀打开,向压力罐供油。当停泵后,卸载阀又恢复起始状态。卸

载阀的动作压力可通过 YV1弹簧预紧力进行调整。

The inertia of the electric motor is very large for large power oil pumps, so it will

Page 116: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

115

take a certain period from staring to working normally. It will do harm to the oil

pump and liquid pressure system, if the load is taken before the screw pump

reaches its nominal flux. If the shut-off valve is adopted, the oil pump will stay in the

condition of load-shedding when initiating. Till the rotation speed of the electric

motor reaches a special value, can the oil pump output the pressured oil in nominal

pressure and flow.

The shut-off valve consists of shut-off pilot valve YV1 and the mainly valve

CV1.

When the oil pump starts to work, the backwards valve CV2 is in the state of

close, due to P1. The shut-off valve is in the state of open because of the spring.

There is no pressured oil in the control cavity in the mainly valve CV1. The

pressured oil in the oil pump return to the oil return tank through the mainly oil

hole CV1.As the motor rotates faster and faster, the pressure in the P is

increasing. When the control oil reaches the upper cavity of the shut-off valve,

and overcome the power of the spring, the piston will move and close the shut-off

valve. At this time, the pressured oil comes into the control cavity of CV1, and

makes it close. As a result, the pressure in P reaches its nominal value, and the

one-way valve is opened to offer oil to the pressure tank. When the pump stops,

the shut-off valve restore to the initial state. The working pressure of the shut-off

valve can be adjusted by the preset spring force of YV1.

10.4.4.4.2 安全阀 Security Valve

安全阀是为保证压力罐内油压不超过允许值而设置的泄放装置,以防止油泵与压

力罐过载,并保护其安全。

安全阀是由安全先导阀 YV2和主阀 CV1组成。

当发生故障时,油泵仍然运转,油压继续升高,当压力作用于先导控制阀 YV2的

推力大于整定弹簧力时,则 YV2 动作,使 CV1 控制的油排泄。此时,在 P 口压力作

用下主阀 CV1 被推开,逆止阀 CV2 关闭,使油泵工作在自循环状态下,压力罐及油

泵都能保持在额定的压力下工作。

The security valve is a kind of leaking equipment set for safety, to make sure

Page 117: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

116

that the oil pressure in the pressure tank will not exceeds some allowable valve.

The security valve consists of security pilot valve YV2 and mainly valve CV1.

When fault happens, the oil pump works all the same, while the oil pressure

increases. When the pushing force to the pilot control valve YV2 caused by the

pressure exceeds the preset spring power, the YV2 works to expel the oil controlled

by CV1. In the meantime, the mainly valve CV1 is pushed away by the pressure of P,

and the backwards valve CV2 closes. The oil pump works in the status of

self-circulation, and the pressure tank and oil pump works in the nominal pressure

all the same.

10.4.4.4.3 卸荷阀 Load-Shedding Valve

卸荷阀(即旁通阀)是由卸荷先导阀 YV3与主阀 CV1组成。它是为油泵作连续运

行而设置的。油泵采用连续工作时,压力罐内的压力随流量而变化,当输入流量大于

输出流量时,压力来自油泵控制油源,因为 CV1 控制腔泄油,使 CV1 活塞被推开,

主油道压力油随之排油泄荷,使油泵工作在自循环状态。随着系统的消耗,压力罐内

油压逐渐降低,当压力罐的压力达到工作油压下限时,卸荷先导阀 YV3在弹簧力作用

下关闭。CV1控制腔随着建压而关闭主阀,油泵恢复向压力罐供油。安全阀和卸荷阀

动作压力,可以分别通过 YV2、YV3的弹簧予紧力来调整。(无此工矿,将此阀切除)

The load-shedding valve ( i.e. by-pass valve ) is composed of the

load-shedding pilot valve YV3 and the mainly valve CV1, and is set for the

continuous working of the oil pump.

The oil pump works all day long, and the pressure of the pressure tank

changes as the flow. When the input flow is larger than the output one, the

pressure will increase. When the working pressure is larger than the upper limit,

the pressure of the control cavity in the load-shedding pilot valve YV3 overcomes

the spring force, and cut off the oil resource from the oil pump. The control cavity

of CV1 gives the oil out, and the piston of the CV1 will be pushed away. The

pressured oil in the mainly oil circuit leaves out, and the oil pump will work in the

self-circulation status. As the consuming of the system, the oil pressure in the

pressure tank decreases. Till the power falls below the lower limit of the working

Page 118: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

117

oil pressure, load-shedding pilot valve YV3 will be closed by the spring force. The

control cavity of CV1 closes the mainly valve, and the oil pump restarts to supply

oil to the pressure tank. The operation pressure of the security valve and the

load-shedding valve could be adjusted by the preset spring force of YV2 and YV3.

(There is no such work condition, please cut off this valve)

10.4.4.4.4 逆止阀 The backwards valve

在压力油通往系统前设有一逆止阀 CV2。由于 P1压力的作用,逆止阀处于关闭状态。

油泵启动后,经卸载阀 YV1的卸载作用,直到主阀 CV1关闭,P 口的压力上升到一定

压力克服逆止阀背压,打开逆止阀向压力罐充油。

There is a backwards valve CV2 in the way of the pressured oil to the system. It is

closed because of the pressure of P1. When the oil pump starts,with the help of the

shut-off valve YV1,the mainly valve CV1 closes. The pressure of P increases to a

certain value, and overcome the of the backing pressure of the backwards valve,

so that,the backwards valve is opened to supply oil to the pressure tank.

10.4.4.5 组合阀调整与安装 The Adjustment and Checkup of the Combination Valve

10.4.4.5.1 调整安全阀 Adjust the security valve

调整 YV2的调节螺钉,使主阀 CV1在油压高于工作油压上限 2%后开始排油,在

油压高于工作油压上限 16%之前应全部开启,(本阀可在高于工作油压上限 10%之

前就可全部开启)达到全排油,并使压力罐内的油压不再升高。当压力降到工作油压

下限之前应全部关闭。调整时按顺时针方向缓慢转动螺钉,压力逐渐达到整定值,反

复调试几次,整定压力值无变化后,将调节螺钉用螺母锁紧。

Adjusting the adjusting screw of the security pilot valve YV2, once the oil pressure

of the main valve CV1 exceeds the upper limit of the working oil pressure by 2%,

begin to expel the oil. And it should be totally opened, before the oil pressure

exceeds the upper limit of the working oil pressure by 16%,(This valve could be

totally opened, before the oil pressure exceeds the upper limit of the working oil

pressure by 10%), so as to drain all the oil, and stop the increase of the oil

pressure in the pressure tank. Before the pressure decreases till the lower limit of

Page 119: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

118

the working oil pressure, it should be closed totally. Rotating the bolt clockwise

when adjustment, the pressure will reach the setting value gradually. Do it time and

time again, till the setting value does not change any more, and lock the adjusting

screw with nut.

10.4.4.5.2 调整卸荷阀 Adjust the relief valve

通过旋转卸荷先导阀 YV3的调整螺钉,使主阀 CV1在压力罐内压力高于工作油压

上限时开始排油,随即全排。并使压力罐内油压不再升高,当压力降到工作油压下限

时应全部关闭。

调整方式与安全先导阀相同。

Rotating the adjusting bolt of the relief pilot valve YV3, once the pressure in the

pressure tank of the main valve CV1 exceeds the upper limit of the working oil

pressure, it begins to drain oil, till empty. Make sure the oil pressure in the pressure

tank will not increase, and close down till the pressure diminishes to the lower limit

of the working oil pressure.

The adjusting manner of the relief pilot valve is the same as that of security pilot

valve.

10.4.4.5.3 卸载阀检查 Check the unloading valve

油泵电机从静止状态到额定转速时,卸载时间一般在 2-6 秒范围内,卸载时间若太

长,应仔细清洗零件,保证活塞滑动轻快,没有卡阻现象,或加大阻尼节流孔,卸载

时间若太短,应减小节流孔,延缓 YV1的动作速度。

The duration time for oil pump electrical motor, from stationary state to nominal

rotation speed, is about 2-6 seconds. If the duration time is too long, please clean

the parts carefully, and make sure that the piston slides trippingly, without any

baffle, or increase the orifice. Otherwise, if the duration time is too short, please

diminish the orifice, prolonging the activity of YV1.

10.4.4.5.4 逆止阀检查 Check the backwards valve

观察油泵停止工作后,逆止阀是否能迅速关闭严密,防止压力罐的油倒流,若动作

不灵活,应检查阀芯是否有卡阻,控制孔是否堵塞,排除异常后重新试验。

Once the oil pump stops working, make sure the backwards valve shut down

immediately and tightly, so as to prevent the oil in the pressure tank flowing

Page 120: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

119

backwards. If the valve is not flexible, please check the spool and the control hole.

Please test again, when the abnormality is already get rid of.

在拆除先导阀 YV1 YV2 YV3及阀盖之前,必须将组合阀通向压力罐油路上的截止阀

关闭,因为先导阀的控制油来源于单向阀的后级。关闭截止阀可避免压力油从控制口

喷出。

Make sure to chose the shutoff valve in the oil circuit from the combination valve to

the pressure tank, before the removal of pilot valve (YV1 YV2 YV3) and cover.

Because the control oil of the pilot valve comes from the latter of the one-way valve.

Closing the shutoff valve will prevent the oil under pressure from rejecting through

the control hole.

the vane zero and full- closed values. The over-high value shall be more than

full-closed values and the excessively low values shall be less than zero(2×zero

value- full-closed value). The value range is the larger the better。

调速器各项功能试验

Functional Tests of Governor

当以上各项调整完毕,且外部接线完成后,即可进行各项功能试验。

With abovementioned adjustments and external wirings finished, the functional

tests then can be done.

(1)开机试验:合开机令,调速器按闭环开机规律将机组开至空载开度,且电

气开限自动为空载开限。在开机过程中,如果测频故障,导叶自动关至空载开度。如

果跟踪频给灯亮,则机组频率跟踪频给,否则机组频率跟踪网频,以更快地并网。正

常运行时,跟踪网频灯亮,机组频率跟踪网频,若网频故障,调速器自动跟踪频给。

Startup trial: command startup, the close loop startup rules of servomotor will

make units the no-load opening and no-load opening to electric limit

automatically.in the coursr of starup, if frequency breaks down, guide vane closes

automatically to no-load limit, if tracing frequency indicator is on, the unit will follow

given frequency for synchronization. If running normally, tracing net frequency turns

on and the unit will follow, but if breakdown happens, the servomotor will trace

given frequency automatically。

(2)在空载状态,若机组跟踪频给,按面板上的“频给增”即可增加频给,机组转

速也跟随升高,按“频给减”即可减少频给,机组转速也跟随降低,利用此功能可将机

组频率调节至 45HZ~55HZ 之间任一频率。在空载状态,调速器为频率调节。

146

Under no-load condition: if the unit trace given frequency, this frequency can

be got by pressing button—increasing given frequency, accordingly, the unit

rotational speed is rising; in the same way, this frequency can be decreased by

pressing button—decreasing given frequency, accordingly, the unit rotational

speed is down. With this function, the unit frequency can be adjusted among

45HZ~55HZ. The Governor now is adjuatable frequency。

12.3 调速器的检修与维护 Governor Inpsection and Maintenance

12.3.1 日常巡视时,应注意 Pay attention to following items while daily

checking:

(1)检查电机或比例伺服阀的温度;

check the temperature of motor proportion servo valves;

(2)机组带稳定负荷时,电机或比例伺服阀应不动,若电机或比例伺服阀来回

抖动不停,应切手动运行,检查抖动原因;

the motor or proportion servo valves shall keep still with rate load. If electric-

mechanics is shaking, change it into manually running and examin;

(3)滤油器压力检查,若压力降低,应清洗滤网;

Exam the oil-filter pressure; then clean meshes if the pressure is too low。

警告 warning

只有在参数选择好后才可自动开机、停机、甩负荷.

Only after the right parameters chosen , automatic startup, shutdown , load rejection can be allowed.

安装或检修后第一次开机需先手动开机到额定转速,若残压低于

0.3V,则须先加励磁,使调速器能可靠测到机组频率,然后将调速器切

自动,选择好调节参数后才可自动停机、自动开机。

The first startup after installation or repairing need manual startup to

rated speed , if the redundent voltage is lower than 0.3v ,it needs to

excitation to make sure the governor can measure the frequency of

units ,andthen run Governor automaticly , after choosing the right

parameter ,the units can automaticly startup and shutdown.

Page 152: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

151

(4)要注意各故障报警及应急处理,出现故障时,应注意观察机频、网频、导

叶开度表、PLC 输出值及平衡值等。

Attend to breakdown and emergency measurement. Check the unit frequency,

net frequency, guide vane opening meter, PLC output values and balance values

etc if breakdown happens。

(5)故障应急处理 emergency measurements for breakdowns:

当电机或比例伺服阀反馈故障、电机限位、驱动器故障、导叶反馈故障、PLC 故

障时,驱动器电源断开,电机失磁,无油电转或比例伺服阀复中,接力器保持当前开

度不动,在这种情况下, 好将调速器切机手动运行,通知维修人员检修。

When breakdown happens in electric-mechanical feedback or proportion servo

valves, electric-mechanical limit, drivers, guide vane feedback, drivers are power

off, motor is out of magnetism, oil-free electri-hydraulic or proportion servo valves

comes to the middle, and the servo motor remains current opening. In this case,

run Governor manually, then notify to servicemen.

出现测频故障时,在空载工况应停机,在负载工况, 好切电手动运行,若无频

率抖动,也可自动运行,增减负荷,只是无频率调节功能。

If breakdown happens, the Governor with no-load working conditon shall stop;

it is better to be electric manually running in load condition. It also can run without

frequency shaking. However, Increasing /decreasing only is a non-frequency

adjusting function.

PLC 电池电压低灯亮时,不能关闭调速器电源,以免 PLC 程序丢失,此时应检

查是电池接触不好,还是电池电压真的过低?若确认 PLC 电池电压过低,应在一个

星期内更换,更换电池时应防止手上带静电。PLC 电池电压低时,调速器仍能正常运

行。

The Governor shall not be power off in order to protect PLC program when

low- voltage indicator of PLC batteries is on. It is necessary to check batteries and

its voltage (whether it is too low or not). If it is because of too low voltage, batteries

shall be replaced (stati electric shall be avoided) in one week. However, the

Governor still can run normally with too- low batteries voltage.

若电液转换器是无油电转,则每两个月应加一次润滑油(透平油即可),加油时

Page 153: W_Z_T系列水轮机微机调速器说明书-W_Z_T Series Hydraulic Turbine Microcomputer-based Governor  INSTRUCTION

应注意不要深入加油孔太深,以免碰上里面的滚珠丝杆。

If taking oil-free electro-hydralic transducer as transmitter ,it shall be

maintained by lubrilating oil (turbine oil) every two months. In lubrication, do not go

to deep of oil hole to avoid meeting ball screw.

12.3.2 检修时,应注意 Pay attention to following items while daily maintaining:

(1)通过触摸屏检查反馈采样值是否有波动,若波动值超过 PLC 采样通道满量

程的 0.2%,需检查反馈及其电缆传输回路是否正常?这里的反馈是指调速器的模拟

量反馈,可以是导叶反馈、桨叶反馈、导叶电机反馈、桨叶电机反馈、导叶伺服比例

阀反馈、桨叶伺服比例阀反馈、功率反馈或水头反馈等。

(1) Checking if feedback sampling values have fluctuate via Touched LCD, if the

fluctuate value exceed PLC sampling channel 0.2% of full range , it needs to check

if the feedback and cable transmission loop are normal . The feedback can be

governor’s simulation feedback or guide vane feedback , runner blade

feedback,guide vane motor feedback ,runner blade motor feedback , guide vane

servo propotional feedback , runner blade servo propotional servo feedback ,power

feedback or water head feedback.

(2)检查无油电液转换器的机械零点是否漂移?导叶切机手动后,接力器应保持不

动,否则应调整机械零点。机械零点调整后,应将电气零点重新设定,否则就不能与

机械零点保持一致。

Check whether the mechanic zero position of the oli-free electro-hydraulic

converter have been drifted. Run guide vane manually and keep servomotor still,

otherwise, the mechanic zero position shall be regulated. After its regulation, reset

the electric zero position, or it would not conform to that of mechanics。

(3)检查调速器各端子是否有不该接大地的却与大地相连。

Check whether Governor terminals are suitable for earth connection。

(4)滤油器检查,看滤网是否堵塞,滤油器压力是否正常。

Check oil-filter to see whether the mesh is jammed and the pressure works well or

not。

(5)其它一些常规的检查维护等。

(3)若故障继电器接触不良或损坏,也会出现 PLC 故障报警。Bad contact or

damage of the malfunction relay may also brings PLC fault alarm.

2、电源故障:Power supply fault

电源故障分动力电源故障和控制电源故障。The power supply faults are

consisted of power supply fault and control supply fault.

(1)动力电源故障:Dynamic power supply fault

若动力电源回路出现故障,系统就会发出动力电源消失报警,动力电源监视继电

器灯灭。

If any dynamic power supply circuit fault happens, the system will send

dynamic power disappearance and the light of dynamic power monitoring relay is

off.

出现故障的原因可能是:三相交流电源断线缺相;I 路动力电源和 II 路动力电源

有一路动力电源消失;动力电源监视继电器接触不好或损坏;

And reasons may be as following: wire breaking or phase lack of three-phase

AC power supply; disappearance of one circuit of circuits I & II dynamic power

supply, bad contact or damage of the malfunction relay.

(2)控制电源故障 Control power supply fault:

控制电源取至 I 路动力电源的一相和 II 路动力电源的一相及直流电源,三者互为

备用,若控制电源故障,请检查 I 路和 II 路三相交流动力电源及直流电源回路是否正

常,中心线接线是否正确。

The control power supply selects until No.1 dynamic power supply phase

1,No.2 dynamic power supply phase 1 and DC. And they are backup for each other;

if control power supply fails, please check whether No.1 and No.2 three phases

dynamic power supply and DC , and center wire are normal.
