Minutes of the meeting held on 29.4.14 to discuss the suggested revisions in System Protection Schemes(SPS) for secured operation of the All India Grid

A meeting was held on 29.4.14 at WRLDC, Mumbai to discuss the revisions proposed by NLDC in the System Protection Scheme (SPS) related with synchronization of Southern grid with NEW grid and its implementation process. NLDC communication dt 11.4.14 is enclosed as Annex‐I. The list of participants is enclosed in Annex‐II. Following are the discussion proceedings.

Member Secretary, WRPC welcomed all participants to the meeting. In his opening remarks, he stated that the objective of this meeting is to deliberate and implement the revised schemes suggested by NLDC based on the operational experience of the All India grid post synchronization of NEW grid with Southern grid on 31.12.13. For smooth synchronization of Southern grid with NEW grid several System Protection Schemes (SPS) were formulated by NLDC and implemented by all concerned in Western Region before synchronization. It was also decided that based on the experience of operation of All India grid the schemes would be reviewed.

He mentioned that the concerns raised by participating generating status regarding frequent operation of SPS leading to generation loss had been taken up with NLDC and CEA and also discussed in the WRPC forum. The revisions have been suggested considering more number of generators in the W3 area so as to provide required relief during SPS operation. He informed that NLDC have has taken cognizance of the WR Concerns and in view of the operational experience with SR they have suggested revisions which have increased the number of utilities taking part and reducing the relief also for individual generating utilities.

He requested WRLDC to briefly summarize the SPS operations in the last 4 months and also elaborate the SPS proposed by NLDC.

GM, WRLDC stated that though oscillations of 0.2 Hz could be observed in Raichur‐ Sholapur in the event of tripping of units in Southern Grid, these were getting damped also. The first swing was generally observed to be of higher magnitude (115‐125% of the lost generation) and subsequently the oscillations were getting damped. It was stated that the proposed scheme suggests a time delay of 2.5sec, so as avoid SPS operation at the first half cycle of oscillation. WRLDC made a presentation on the performance of the SPS during the last 3 months along with the suggested revisions as proposed by NLDC. It has been observed that SPS‐1, 2 and SPS‐5 have operated frequently during the last three months while the others have not operated. Details of SPS operation is summarised below:‐ Period SPS

Name SPS Criteria No. of

31.12.13‐31.3.14

SPS‐2 dP/dt of Sholapur‐Raichur>400MW/sec

13 ‐do‐

SPS‐5 Wardha‐Parli >750MW 27 Unit tripping in SR/ demand ramp up in SR or Maharashtra

The following issues were also emphasized for reliable operation of SPS:‐

1. Improving reliability of SPS through redundant measurements, logic, communication path and end terminals. 2. Use of metering core of CTs and PTs for analog measurements used in the SPS logic, particularly where the same

is based on steady state flows crossing a particular value. 3. Need to cover more generators in the NEW grid so that adequate relief is available as in many instances, the

antecedent generation in many of the generators selected remain already very low. 4. Wiring of each SPS operation to the local substation Event Logger. 5. Triggering of each SPS action and the receipt of signal at each point to be recorded in SLDC/RLDC/NLDC SCADA 6. Prompt submission of data to RLDCs regarding SPS action in the prescribed format.

7. Each instance of inadequate relief through SPS to be thoroughly analysed and remedial actions taken so as to have increased confidence on the SPS reliability

The proposed revisions were agreed by members and the revised settings along with backing down quantum by WR generators is given in detail in Table‐I. A detailed discussion was held on SPS setting of Wardha Parli 400kV D/C corridor which is heavily loaded post commissioning of number of generators within central part of Western Grid. Representative of Maharashtra stressed the need of transmission system at Sholapur. It was stated that back end network including following lines be completed at the earliest. 1. 765kV Wardha‐Aurangabad D/C 2.765kV Pune‐ Sholapur(PG) D/C 3. 765kV Aurangabad‐Sholapur The representative from GETCO SLDC also supported the need for completion of the associated transmission network as above. WRLDC has pointed out that the SPS for Wardha‐Parli S/C loading>750MW has operated 10 times due to Maharashtra load ramp up and 9 times due to SR load ramp up in the month of March’14. It has been observed that this SPS operates irrespective of increase in flow of Sholapur‐Raichur line and has operated even when power was being imported from Raichur(SR) to Sholapur(WR). Further during outage of 400kV Akola‐Aurangabad D/C from 25‐27th April’14, there was very frequent operation of this SPS and as a precautionary measure, the SPS setting of 400kV Wardha‐Parli S/C flow was increased to 800MW to avoid frequent operation of SPS beside safe operation of the units. Since Wardha‐Parli loading is sensitive to Western Maharashtra load as well as SR load, it was emphasised that load shedding in Western Maharashtra is also essential. SLDC, MSETCL expressed their concerns for implementing load shedding and hence assured to immediately pick up generation at Koyna whenever the flow on Wardha flowgate crossed 2480MW. MSETCL also agreed to implement generation reduction in the identified generators in Maharashtra as per the revised SPS. Further, disarming of SPS by NTPC,Mauda on its own and not participating in automatic generation reduction in case of SPS triggering due to Wardha‐Parli overloading was viewed seriously and MS,WRPC informed that this is a serious violation of the decision of WRPC and all the SPS actions have to be automatic. NTPC Mauda agreed to arm the SPS for automatic generation reduction. Power Grid expressed that they would require at least a month time as the revised scheme involve process of hardwire procurement. In view of high summer demand in Maharashtra vis‐a‐vis anticipated frequent SPS in Wardha Parli ,it was also decided to continue with the changed SPS setting of 800MW for Wardha‐Parli S/C loading till the revised scheme is implemented. It was also suggested that revision as regards to introduction of time delay setting of 2.5 sec could be implemented immediately, till other revision such as inclusion of more generators are implemented.

Summarily it was decided that, all control actions by generators in Western Region under various cases of SPS would be backing down by 800MW in proportion to their capacity under commercial operation . POWERGRID was requested to extend communication signals for implementation of the revised schemes wherever required. It was decided that the whole action for implementing revised SPS has to be completed within one month and any difficulty/delay faced by concerned agency may be addressed to WRPC for further action. Meeting ended with vote of thanks to chair and participants.

Revisions in System Protection Schemes(SPS)-NEW & SR grid synchronisation

(part of NLDC communication NLDC/SR_synch_SPS/ dated 11th April 2014)

S. no

Triggering criteria for SPS(implemented) SPS action implemented Proposed revision in SPS Remarks

1 765kV Sholapur‐Raichur flow > 800 MW: SPS‐1 Total flow on 765 kV Sholapur‐Raichur 2 x 765 kV S/C lines crossing a preset value, say 800 MW in Sholapur to Raichur direction sensed both at Sholapur and Raichur.

Western Region 500MW Gen Back down JPL ‐ 350MW KSK ‐ 150MW DB power=0 Southern Region 500 MW Load Shedding Tamilnadu‐ 146MW Kerala ‐ 125MW Karnataka‐ 104MW Andhra Pradesh 125MW

Suggestion: SPS should trigger when flow on 765 kV Sholapur‐Raichur S/C line crosses 1000 MW and remains above 1000 MW for 2.5 seconds. It should also act instantaneously when the power flow crosses 1500 MW. Western Region 800 MW Gen Back down More generators such as Lanco Amarkantak, KWPCL, BALCO, JPL Ext, NSPCL etc. must be covered in W3 area so that 800 MW relief is available under all conditions. Southern Region No Change

Rationale: SPS should not operate for the first swing arising out of generating unit trip in Southern Region and antecedent flows from Sholapur to Raichur is less than, say 400‐500 MW, towards Southern Region. It has been observed from synchrophasor data that the first spike is typically 115‐125% of the generation lost in Southern Region and oscillations of the order of 0.20 Hz are observed. Further, one argument cited by generators towards inadequate relief is the low antecedent generation on these units. As this would be a highly probable scenario, SPS wiring may be done for more quantum so that 800 MW

relief is always available.

2 Rate of change of flow >400 MW/Sec: SPS‐2 Rate of change of flow crossing 400 MW/second in the Sholapur to Raichur direction.

Same as above

Suggestion: Pending a clarification by POWERGRID as to how dP/dt is actually computed at field level, this setting may be blocked temporarily.

The logic for computing dP/dt needs to be clarified by PowerGrid as it is observed from synchrophasor data, it appears to have been activated at lower values also.

3 SPS for Loss of 800 MW import by SR: SPS‐3 Loss of import on 765 kV Sholapur‐Raichur by more than 800 MW due to tripping of these lines.

Same as above

Suggestion: In case of loss of import on 765 kV Sholapur‐Raichur by more than 800 MW due to tripping of these lines, only load shedding should occur in SR. Tripping or backing down of generators may therefore be blocked.

Rationale: Load Generation balance in NEW grid may be taken care by governor action. In SR, to arrest a sharp frequency fall, load shedding through SPS is required.

S. no


4 400 kV Raipur‐Wardha : SPS‐4

Flow on 400 kV Raipur‐Wardha any circuit crossing 800 MW sensed at Raipur OR tripping of any one circuit of 400 kV Raipur‐Wardha carrying 650 MW or above.

Western Region 800MW Gen Back down JPL ‐ 600MW KSK ‐ 200MW DB Power – 0 MW Southern Region 800MW Load Shedding (Kudankulam group) Tamilnadu‐ 290MW Kerala ‐ 135MW Karnataka‐ 195MW Andhra Pradesh 230MW

Suggestion: Triggering point may be modified as ‘antecedent flow on either of the 400 kV Raipur‐Wardha circuit crossing 850 MW and remaining above this value for 2.5 seconds OR tripping of any circuit when the antecedent flow is greater than 700 MW. Western Region 800 MW Gen Back down More generators such as Lanco Amarkantak, KWPCL, BALCO, JPL Ext, NSPCL etc. must be covered in W3 area so that 800 MW relief is available under all conditions. Southern Region No change

Rationale: To take care that there is no SPS action in the first spike following a large event. Further, one argument cited by generators towards inadequate relief is the low antecedent generation on these units. As this would be a highly probable scenario, SPS wiring may be done for more quantum so that 800 MW relief is always available.

S. no


5 400kV Wardha‐Parli line : SPS‐5

Flow on 400 kV Wardha‐Parli any circuit crossing 750 MW or tripping of any one circuit of 400 kV Wardha‐Parli section carrying 600 MW or above. Sensed at Wardha.

Western Region APL Tiroda ‐ 600MW NTPC Mauda ‐ 200MW IEPL – 0 MW Southern Region 800 MW Load Shedding (Kudankulam group) Tamilnadu‐ 290MW Kerala ‐ 135MW Karnataka‐ 195MW Andhra Pradesh 230MW

Suggestion: The triggering point for steady state loading may be revised to the flow crossing 850 MW each circuit with a delay of 2.5 seconds OR tripping of any circuit when the antecedent flow is greater than 750 MW. Flow may be sensed at Wardha end. Western Region 800 MW Gen Back down More generators such as Koradi, Khaperkheda, Chandrapur, Indiabulls need to be covered so that 800 MW relief is always available. 250 MW load shedding in Maharashtra west of Sholapur. Southern Region No change; however position can be reviewed once

Rationale: Time delay required to take care of the first spike. Further, Wardha‐Parli line despite having Quad Moose conductor is 334 kms. long and any tripping of one line when the antecedent flow is more than 750 MW leads to the angular separation between Wardha and Parli crossing 30 degrees. Without automatic corrective action, oscillations will not subside as per simulations. The second unit at Mauda and the fourth unit at Tiroda have been synchronized and declared under COD recently. These had not been assumed in the initial studies. SLDC Maharashtra shall regulate load/generation in Maharashtra whenever total power flow on Wardha flowgate (400 kV Wardha‐Akola D/C + 400 kV Wardha‐

S. no


Maharashtra implements 250 MW load shedding suggested above

Parli D/C) crosses 2480 MW. Power order on HVDC Chandrapur‐Padghe bipole shall also be maximized. Further, to ensure that 800 MW reduction in generation is achieved, more generators need to be covered in eastern Maharashtra. NTPC Mauda relief is generally negligible and the station schedule is also generally low. The loading on Wardha‐Parli is sensitive to both western Maharashtra load as well as Southern Region load; hence load shedding is also required to be done in western Maharashtra.

6 400 kV Parli‐Sholapur : SPS‐6

Antecedent flow on any circuit crossing 800 MW or tripping of any one circuit of Parli‐Sholapur carrying 600 MW or above.

Load shedding by Maharashtra to be implemented. 300 MW generation pick up at Koyna

Suggestion: The triggering point for steady state loading may be revised to the flow crossing 800 MW each circuit with a delay of 2.5 seconds OR

Rationale: 2.5 seconds delay to take care of the first spike not leading to SPS action.

7 765kV Raichur‐Sholapur line current exceeding 800 Amp (1000 MW on either direction): SPS‐7

Tripping of 765kV Raichur‐Sholapur line with 10 seconds delay.

No change suggested for the Sholapur to Raichur direction which is retained at 1000 MW with ten (10) seconds delay. Ordinarily SPS‐1 action should prevent this situation from arising. In the eventuality that SPS‐1 does not act and this SPS operates, SPS‐3 above should act. Tripping of 765 kV Sholapur Raichur on SPS due to the >1000 MW flowing in the reverse direction i.e., SR to NEW grid may be blocked. This setting would be reviewed with reinforcements in the upstream and downstream network.

Rationale: This setting was decided considering that SR could safely withstand the 1000 MW loss of import or export. Sustained operation above 1000 MW in the Sholapur to Raichur direction would indicate that the upstream and downstream systems are stressed and therefore SR system needs to be separated through tripping of 765 kV Sholapur‐Raichur. For the reverse direction, the possibility of S1 and S2 areas getting separated due to a contingency is credible. There would be a sudden increase in flow from Raichur to Sholapur. Tripping 765 kV Sholapur‐Raichur under these circumstances may further worsen the situation in S1. Hence this is proposed to be blocked.

10 Talcher‐Kolar SPS‐10 In case of single pole or bipole outage or blocking of Talcher‐Kolar HVDC sensed at Talcher HVDC terminal,

Trip signal be extended to nearby generators such as Sterlite, GMR, JITPL and Talcher Stage‐I for gen reduction of 600 MW so that the injection into NEW grid is restricted to 450 MW. Eastern Region:‐ Sterlite = 350MW GMR = 250MW JITPL = 0 This would be in addition to SPS 1000 already in operation at Talcher‐II.

Eastern region: JITPL unit also needs to be connected. Further relief from GMR was not available on 25th March 2014 when one pole of Talcher‐Kolar HVDC bipole tripped; so the unit selection logic at GMR needs to checked. 600 MW relief must come from Sterlite, GMR and JITPL under all conditions.

Rationale: Even after Southern region is synchronized, the system is still not planned for single pole of Talcher‐Kolar HVDC bipole going out.

11 Kudankulam : SPS‐11 SPS of Kudankulam Unit and SPS of Talcher‐Kolar Pole trip at Kolar end are having the same group of loads for shedding and these needs to be segregated at the earliest by identifying separate loads for Kudankulam SPS.

Note: SPS-1, 2 and SPS-5 have operated frequently during the last three months while the others have either not operated or operated infrequently. Notwithstanding the above revisions suggested, the following are also important. o Improving reliability of SPS through redundant measurements, logic, communication path and end terminals. o Use of metering core of CTs and PTs for analog measurements used in the SPS logic, particularly where the same is based on

steady state flows crossing a particular value. o Need to cover more generators in the NEW grid so that adequate relief is available as in many instances, the antecedent

generation in many of the generators selected is already very low. o Wiring of each SPS operation to the local substation Event Logger. o Triggering of each SPS action and the receipt of signal at each point to be recorded in SLDC/RLDC/NLDC SCADA o Prompt submission of data to RLDCs regarding SPS action in the prescribed format. o Each instance of inadequate relief through SPS to be thoroughly analysed and remedial actions taken so as to have increased

confidence on the SPS reliability.
