1. INTRODUCTION
The Marble River collector substation is being constructed for the Horizon Wind Energy
Marble River Wind Farm which consists of 73 wind turbine generators (WTGs) each with a
nominal rating of 3.0MW for a total generation capacity of 219MW. TRC is providing
protective relay settings for the collector substation. Guidance for the protective relay
settings, substation control and automation, as well as arc flash studies are provided by
POWER Engineers, Inc. This document provides the criteria used by TRC to complete the
relay settings.

2. CRITICAL NOTES AND ASSUMPTIONS
2.1 POWER Engineer’s supplied a settings guide, Marble River Protective Relaying
Functional Descriptions – Revision 0, which was used where applicable in the
completion of the collection system relay settings. This document is located in the
Appendix for reference.
2.2 All impedance and short circuit contribution information in the supplied short circuit
model used for calculating relay settings is based on Horizon/EDPR information supplied
to the date of this document. All calculations for the system short circuit model are
located in the Appendix for reference.
2.3 Proper coordination of protective devices may not have been achieved to be able to protect collector substation equipment. These instances are documented in the settings
calculations.
2.4 All protective equipment for T2 and the 230kV system are located in the point of
interconnection station operated by NYPA, Patnode Substation, and are excluded from
this document. Overcurrent protection is provided by the following relays to the 34.5kV
collector substation: 87TBP/T2, 87TP/T2 & 87TS/T2.
2.5 Capacitor Banks C1-C3 have been removed from the design of the collector substation
and therefore no documentation of protective devices is provided.
3. PROTECTION OVERVIEW
3.1 The following table lists the protective devices covered by this document. The name,

F2-F8 are similar. Additional
details available in setting
calculations.
T2 lowside overcurrents
provide limited back up
protection to collector circuits.
This is acceptable since
collector protection has breaker
failure.

Maximum and mininum fault conditions examined. Maximum conditions are with all WTGs in service
and a normal utility system. Minimum conditions are with no WTGs in service and a weak utility
system. A situation where T2MR is open will leave an ungrounded 34.5kV bus. Additional protection
will be required to detect a phase to ground fault in this scenario.

Relay will operate with a primary differential current of 123A,pri. Mininum expected
fault for a normal operating condition is 10,664A,pri. Maximum expected current for
station service secondary fault is approximately 277A. Station service transformers
have a primary fuse and secondary fuse. The primary fuse will clear in
approximately 0.01s for a primary fault and 0.17s for a secondary fault. The
secondary fuse will clear in approximately 0.01s for a close in secondary fault. A
delay of 3cyc has been added to the differential trip to allow coordination with faults
where either the station service primary or secondary fuses clear instantaneously.
Since the differential can detect a station service fault the possibility exists for a
bus trip for a fault before the secondary fuse protection. The desensitizing of the
pickup or increased delay required for the propoer coordination of bus differential
was not chosen due to the probability of this fault condition compared to that of abus fault. Additional protection will be required to detect a ground fault on the
34.5V bus if energized with T2MR open.

1 ‐ Damage to cables can result from breaker/relay failure due to high fault currents with prolonged clearing times
Set Ground Inverse Overcurrent Pickups:
The purpose of this element is to provide protection to the collection feeder cables for high ground fault currents where they
are not protected by Level One. This element will only pickup on forward (towards feeder) faults since there is no
contribution from WTGs for ground faults.
Ground definite time pickup will be set below cable sheath damage curves.
Ground TOC pickup will be set at 3,200 A,pri.
Definite time protection will be utilized. The required time delay is based on: S&C Relay Tot. Clearing Time (0.04s) + 2 cyc
Margin (0.033s) = 0.073s. SEL relays will only accept delays in 1/4cycles. A delay of 0.075s/4.5cyc will be used. This delay
should allow the WTG switchgear S&C relay time to clear a WTG fault before the collection feeder is tripped offline but the
coordination time is less than desirable and may result in a trip of the collection feeder breaker before the WTG 34.5kV
switchgear can clear the fault.
To provide adequate margin with the cable sheath damage curve the pick up of the definite time protection must allow
sufficient time for the fault to clear. This time is: Def. Time Delay (0.075s) + Bkr Time (0.083s) + 2 cyc Margin (0.033s) = 0.191.
For an additional margin of 120%, 0.23s is assumed to be the normal clearing time of a fault by this element. The current
associated with the lowest rated cable (350MCM) at this time is approximately 10,000 A,pri. Set the pickup of the definite
This element will only pickup on forward (towards feeder) faults since there is no contribution from WTGs for ground faults.
Element will be set to detect minimum expected 34.5kV fault.
Ground instantaneous will be set at 125% of downstream coordinating current or 80% of downstream equipment rating,
whichever is
less.
Pickup will be set at a minimum coordinate with WTG 34.5kV Protection or 15% of phase pickup, whichever is greater. 120%
* 50A = 60A,pri @ 34.5kV or 15% * 800 = 120A,pri @ 34.5kV.
TD will be set to coordinate with WTG 34.5kV Protection.
This element may not provide provide protection for cable ground faults with high currents.

Introduction
Project Descript ion
The Marble River collector substation is being constructed for the EDP Renewables’ Marble
River Wind Farm. POWER Engineers, Inc. has been contracted to provide guidance to TRC, the
consultant preparing protective relay settings for the collector substation, in order for MarbleRiver to match as closely as practical, EDPR’s standard protection schemes.
Also included in POWER’s scope of work are the substation SCADA and arc flash studies. This
document will provide the basic criteria by which relay set points may be calculated.

Settings Guidelines
Introduction
This section describes the basic guidelines to be used for implementing the following functions:
Remote SCADA controls
Maintenance Mode
Local/Remote Logic
Breaker Failure Logic
Pushbutton Definitions
Feeder Relay 5 Second Close Delay
Automatic Restoration
Relays without these functions are not in the scope of this document. This document describes
the guidelines on a relay type basis, and it is important to note that the transformer protection and
high-side breaker relays are not included because they are located in the connecting utility
(NYPA) Patnode Substation. Guidelines are organized into relay types serving the same function
(i.e. Collection feeder, etc).
Critical Notes
A Mirrored Bits channel needs to be added between the 2440A Automation Controller
and the 3530 RTAC Logic Controller. This connection is required for implementation of
the automatic restoration scheme.
The 5 second block close timer employed in the collector relays will only be capable ofsupervising SCADA close commands. Pushbutton/Control Switch closures for the
34.5kV breakers are supervised only by the associated 43 switch.
The logic function assignments outlined in this document may require modifications once
the programming of the SEL-3530 Logic Processor is complete.

When the 43 switch is in the “Remote” position, all front panel pushbutton functions
should be disabled.
o Local control is permitted when the 43 switch is in the “Local” position. When the 43
switch is in the “Local” position, the front panel pushbuttons should be active, and all
remote bits should be blocked.
Breaker Failure Logic
Breaker Failure Protection (50BF).
Two breaker failure schemes are used. One scheme uses a low-set current detector
for the supervisory condition; the other utilizes breaker position for the supervisory
condition. The position-based scheme ensures breaker failure timing in the event that
a breaker is called to trip for a voltage condition and/or sufficient current is not
contributed by the wind farm to assert the current detectors. These breaker failure
schemes are implemented using custom logic.
Current-based Breaker Failure Detection
Supervisory current detector set at 0.5 A-sec
Timing
Set the current scheme breaker failure timing to the sum of: Twice the maximum breaker interrupting time
Maximum current detector dropout time (1.5 cycles)
Example logic expression (where “BFI” is any other external breaker failure initiate):

Automatic Restoration
The automatic restoration schemes are mutually exclusive. If scheme B is enabled, and
the user presses PB3, scheme A will be enabled, and scheme B disabled. Similarly, if
scheme A is enabled and the user presses pushbutton PB4, scheme B will be enabled, and
scheme A disabled.
The main breaker relay should trip T2 MR for undervoltage conditions when either of the
automatic restoration schemes are enabled. The relay should trip T2 MR directly, andalso provide indication to the SEL-3530 logic processor via Mirrored Bits.
The undervoltage element should be set according to the following criteria:
Set pickup to 15% of nominal, and time-delay of at least 0.75 seconds to meet FERC
661A requirements.
Ensure that the time delay is set longer than the LVRT or ZVRT characteristic of the
wind turbines.
Element only permitted to trip if T2 MR is closed.
The SEL-3530 Logic Controller will perform the auto-restoration logic and will issue
close commands to the 34.5kV breaker relays.

Arc Flash Maintenance Mode
Overview
Maintenance mode is provided in each of the 34.5kV collector breaker relays to
provide sensitive, high-speed protection during maintenance activities on
downstream equipment.
Maintenance mode is enabled when latch bit four (LT4) is asserted via SCADA
control. SCADA enable/disable requires the 43 switch to be in the remote position.
Maintenance mode cannot be enabled if either of the following conditions are true:
The circuit breaker is open
The relay has declared loss-of-potential
When maintenance mode is enabled the LCD message “!AF MAINT MODE!”should be present.
The following logic expressions are required for correct operation
TR = 51P1*LT4 + 51P1T*!LOP
51PTC = 32PF + 32QF
ELOP = Y
Local/Remote Control
o Remote (SCADA) control is enabled when the 43 switch is in the “Remote” position.
When the 43 switch is in the “Remote” position, all front panel pushbutton functions
should be disabled.
o
Local control is permitted when the 43 switch is in the “Local” position. When the 43switch is in the “Local” position, the front panel pushbuttons should be active, and all
remote bits should be blocked.

Feeder Relay 5 Second Close Delay
Feeder breaker 5 second close delay prevents the breaker from closing for the duration of5 seconds following the breaker opening to allow the wind turbine generators to trip off-
line, utilizing a system variable. The system variable should be set with a 300 cycle
dropout timer, and 0 cycle pickup timer. The variable should be programmed to assert on
a falling edge trigger of 52A (SVx=\52A). SCADA close should be blocked when this
system variable trip output (SVxT) is asserted.

4 Turbine Protection Systems
4.1 Braking Concept
The main brake on the turbine is aerodynamic. Braking the turbine is done by fullfeathering the three blades (individually turning each blade). Each blade has ahydraulic accumulator to supply power for turning the blade. Braking of theturbine is further supported by a braking resistor that is connected to the
permanent magnet generator during shut down. This ensures that torque ismaintained in, for example, grid loss situations.
In addition, there is a mechanical disc brake on the high-speed shaft of thegearbox with a dedicated hydraulic system. The mechanical brake is only usedas a parking brake and when activating the emergency stop push buttons.

4.6 Earthing (Also Known as Grounding)
The Vestas Earthing System consists of a number of individual earthingelectrodes interconnected as one joint earthing system.
The Vestas Earthing System includes the TN-system and the lightning protectionsystem for each wind turbine. It works as an earthing system for the medium
voltage distribution system within the wind farm.The Vestas Earthing System is adapted for the different types of turbinefoundations. A separate set of documents describe the Earthing System in detail,depending on the type of foundation.
In terms of lightning protection of the wind turbine, Vestas has no separaterequirements for a certain minimum resistance to remote earth (measured inohms) for this system. The earthing for the lightning protection system is basedon the design and construction of the Vestas Earthing System.
A primary part of the Vestas Earthing System is the main earth bonding barplaced where all cables enter the wind turbine. All earthing electrodes are
connected to this main earth bonding bar. Additionally, equipotential connectionsare made to all cables entering or leaving the wind turbine.
Requirements in the Vestas Earthing System specifications and workdescriptions are minimum requirements from Vestas and IEC. Local and nationalrequirements, as well as project requirements, may require additional measures.

The above chart applies at the low voltage side of the HV transformer at nominalvoltage ±10% and nominal frequency ±6%.
Reactive power capability at full load on high voltage side of the HV transformeris approx: cosφ = 0.90/0.90 capacitive/inductive.
Reactive power is produced by the full-scale converter. Traditional capacitors are,therefore, not used in the turbine.
The reactive power capability at no-load operation may be reduced up to 50%
due to cooling system capacity constraints.
9.5 Performance – Fault Ride Through
The turbine is equipped with a full-scale converter to gain better control of thewind turbine during grid faults. The turbine control system continues to run duringgrid faults.
The turbine is designed to stay connected during grid disturbances within thevoltage tolerance curve as illustrated:

Power Recovery Time
Power Recovery to 90% of Pre-Fault Level Maximum 0.1 seconds
Table 9-6: Power recovery time.
9.6 Performance – Reactive Current Contribution
The reactive current contribution depends on whether the fault applied to theturbine is symmetrical or asymmetrical.
9.6.1 Symmetrical Reactive Current Contribution
During symmetrical voltage dips, the wind farm will inject reactive current tosupport the grid voltage. The reactive current injected is a function of themeasured grid voltage.
The default value gives a reactive current part of 1 pu of the rated active current
at the high voltage side of the HV transformer. Figure 9-3, p. 29 indicates thereactive current contribution as a function of the voltage. The reactive currentcontribution is independent from the actual wind conditions and pre-fault powerlevel.
As seen in Figure 9-3, p. 29, the default current injection slope is 2% reactivecurrent increase per 1% voltage decrease. The slope can be parameterizedbetween 0 and 10 to adapt to site specific requirements.

Figure 9-3: Reactive current injection.
9.6.2 Asymmetrical Reactive Current Contribution
The injected current is based on the measured positive sequence voltage and theused K-factor. During asymmetrical voltage dips, the reactive current injection is
limited to approximate 0.4 pu to limit the potential voltage increase on the healthyphases.
9.7 Performance – Multiple Voltage Dips
The turbine is designed to handle re-closure events and multiple voltage dipswithin a short period of time due to the fact that voltage dips are not evenlydistributed during the year. For example, the turbine is designed to handle 10voltage dips of duration of 200 ms, down to 20% voltage, within 30 minutes.
9.8 Performance – Active and Reactive Power Control
The turbine is designed for control of active and reactive power via theVestasOnline® SCADA system.
Maximum Ramp Rates for External Control
Active Power 0.1 pu/sec. (300 kW/sec.)
Reactive Power 20 pu/sec. (60 MVAr/sec.)
Table 9-7: Active/reactive power ramp rates.
To support grid stability the turbine is capable to stay connected to the grid atactive power references down to 10 % of nominal power for the turbine. Foractive power references below 10 % the turbine may disconnect from the grid.

9.9 Performance – Voltage Control
The turbine is designed for integration with VestasOnline® voltage control byutilising the turbine reactive power capability.
9.10 Performance – Frequency Control
The turbine can be configured to perform frequency control by decreasing theoutput power as a linear function of the grid frequency (over frequency).
Deadband and slope for the frequency control function are configurable.
9.11 Own Consumption
The consumption of electrical power by the wind turbine is defined as the powerused by the wind turbine when it is not providing energy to the grid. This isdefined in the control system as Production Generator 0 (zero).The followingcomponents have the largest influence on the own consumption of the windturbine (the average own consumption depends on the actual conditions, theclimate, the wind turbine output, the cut-off hours, etc.):

BASIS—The total clearing time-current characteristic curves shownabove are applicable to 60-Hz systems. For 50-Hz systems, add 4milliseconds to the total clearing curve under consideration. Thisadjustment is not necessary when coordination with the source-side circuit breaker, recloser, or fuse is not particularly tight. Inaddition, these curves are applicable over the entire S&C VistaUnderground Distribution Switchgear operating temperature rangeof -40°C to +40°C. No adjustments need to be made to these curvesfor ambient temperatures within this temperature range.
TOLERANCES—Curves are plotted to maximum test points; all varia-tions are minus.
APPLICATION—The maximum continuous current-carrying cap-ability of S&C Vista Underground Distribution Switchgear is 1200amperes. The overcurrent control is capable of sensing current inthe range of 50 to 25,000 amperes RMS.
The total clearing time-current characteristic curves shown aboverepresent the total time required for S&C Vista Underground Distri-bution Switchgear to both detect and interrupt a fault current. Thesecurves should be followed for coordination problems where the tapfault interrupter is applied as a “protecting” device with respect to amain fault interrupter (if present) or with respect to a source-siderelayed circuit breaker or recloser. Fault interrupter operating andclearing times are included in the curves; additional adjustmentsare not required.
Since the time-current characteristics are electronically derived,they are not subject to change due to aging, transient overcurrents,or fault currents. It is, therefore, only necessary to reset the faultinterrupters following a fault-clearing operation.
CONTROL SETTINGS—Phase- and ground-overcurrent curves areset independently using a laptop computer. In addition, thesecurves can be uniquely tailored to the application by enablinginstantaneous and/or denite-time-delay settings shown. Refer toS&C TCC Nos. 695-9-2 (Instantaneous), 696-9-2 (Denite-TimeDelay), and 697-9-2 (Instantaneous and Denite-Time Delay), asrequired.

Directions for Drawing Time-Current Characteristic Curves Using aCombination of Definite Time Delay and Instantaneous Trip Settings
Step 1) Draw minimum tripping and total clearing curves for the (main, tap,or “E” speed) fault interrupter under consideration.
Step 2) Position and align time-current curve created in Step 1 over thedenite time delay curves shown in S&C TCC Number 696-9-2. Draw hori-zontal lines representing the minimum tripping and total c learing times forthe delay band under consideration (32 mSec delay illustrated below).
Step 3) Position and align the time-current curves created in Step 2 overthe instantaneous tripping curves shown in S&C TCC Number 695-9-2.This will require two steps. First using the minimum tripping curve (bot-tom), draw the vertical line representing the selected instantaneous tripvalue (3 kA trip setting illustrated). Then position the curve over the totalclearing curve (top). Draw the total clearing curve corresponding to theselected instantaneous trip value. Take care to show the total clearingcurve as a horizontal line at 40 mSec. This is the fastest clearing timeavailable. Extend the total clearing curve to the maximum available shortcircuit current or 25 kA whichever is lower. The nal curve shape shouldresemble the example shown below.
