MINUTES OF THE SPECIAL MEETING WITH KPTCL ON PENDING ISSUES

1. INTRODUCTION

A Special Meeting with KPTCL on pending issues was held at SRPC, Bengaluru on 17th June 2016.

The list of participants is given at Annexure-I.

Sri S.R.Bhat, Member Secretary, SRPC welcomed all the participants to the Meeting. He informed

that it was very heartening to note that A/R feature had been implemented recently in Chikkodi –

Talangde line. He stated that this meeting had been necessitated keeping in view time constraints

experienced in the OCC Meetings. Certain issues involved regulatory compliance, technical

requirements etc and it would thus be apt to take stock of the situation and identify the way forward

to rectify the issues.

2. LOW VOLTAGES

A Meeting with SLDCs/system study groups to discuss the low voltage and an ATC/TTC issue was

held at SRPC on 26.04.2016 and many recommendations/action points had been finalized. The

Minutes of the Meeting are available at SRPC website. The following had been highlighted:

Physical Regulatory Procedure as enumerated was agreed for implementation. Step 4 was a

critical step and thus SLDCs needed to take action to avoid any situation which would compel

SRLDC to take such step.

In case Specific instructions for opening 220/230 kV and below lines were not adhered by

SLDCs it would be deemed as violation of provisions of IEGC/EA 2003.

SLDCs to take action proactively by observing falling trend/pattern of voltages even before

receipt of SRLDC messages. SLDCs to also furnish the physical regulatory measures to be

taken up at low voltage nodes in their system. It was felt that physical regulatory measures at

220 kV and below would give optimum results than physical regulatory measures by SRLDC.

SRLDC real time messages/instructions to be adhered within 15 minutes of issuance and the

action taken report should be furnished within 30 minutes.

As a drive, faulty capacitor banks to be rectified immediately.

Chairperson, SRPC would be kindly requested to take up the issue with the concerned since it

was threat to system integrity.

Constituents were requested to revert back on utilization (operational/commercial limitations &

possibilities) of reactive support from wind/solar units even when they are not generating.

States to furnish data of load management actions taken to overcome low voltage conditions.

Deliberations in the Meeting

SRLDC pointed out that on many instances the voltage profile around Bangalore remained

critically low (ie. below 380kV) and MVAR drawal was 800 MVAR to 1300 MVAR. Even during

such instances, SRLDC instructions for opening specific lines had not been complied. This

amounts to non-compliance of SRLDC’s directions and violation of Grid Code.

KPTCL pointed out that though specific lines may not have been opened, but downstream lines

were opened. Low voltage issues were more in the month of February and March 2016 due to

reconfiguration of loads necessitated due to fire accident in Sharavathi.


SRLDC clarified that low voltage (high MVAR drawal) was due to the loads in Bengaluru area and

MVAR drawal in & around Bangalore. Sharavathi generation does not support Bengaluru in

reactive energy and thereby non-availability of Sharavathi generation could not significantly

attributed for low voltage scenario at Somanahalli, etc.

It was noted that BESCOM needs to be appraised of the high MVAR drawal and low voltages.

Reactive support both by KPTCL and BESCOM are required to address this issue

comprehensively.

Over loading of lines, weak sub transmission system, no generator in Bengaluru area for reactive

support, inadequate reactive support at transmission and distribution levels were the major causes

for high MVAR drawal and low voltages. This could seriously hamper drawal capability of

Bengaluru area unless concrete steps are taken now.

Recommendations finalized

Real time messages/instructions of SRLDC to be adhered within 15 minutes of issuance and

action taken report should be furnished within 30 minutes.

Retrofitting of Somanahalli and Hoody Capacitor Bank of 30 MVAR each to be expedited. KPTCL

to furnish the action plan within 2 weeks.

Faulty Capacitor Banks to be rectified in Bengaluru adjoining areas of KPTCL system. KPTCL to

furnish the details of faulty capacitor banks and action plan for rectification within 2 weeks.

KPTCL /SLDC would call for a meeting with BESCOM with participation at appropriate level

within 2 weeks and following issues would be taken up:

Special drive on rectifying the faulty capacitors in BESCOM in a time bound manner with

the details of status of capacitor banks.

Tap optimization in the distribution transformers of BESCOM (to reduce drawal of VAR)

Study of additional capacitor requirements. This needs to be taken up by BESCOM on

urgent basis.

Discom wise or location wise limitation on MW drawal due to low voltages and high

MVAR drawal.

Extending scope of maintaining power factor by other consumers (presently being limited

to HT Consumers).

BESCOM to identify feeders for Physical Regulatory Procedure based on the MVAR

drawal by the respective feeders

Senior Managements of KPTCL and BESCOM to be appraised that MW drawal capacity had

reached saturation and could be curtailed unless voltage profile is improved and also if sub--

transmission system is not strengthened on war footing basis. Future increase in loads and even

share from Yeramarus, Bellary, LTA etc., would be difficult to meet keeping in view the voltage

profile.

SLDC could envisage taking up the issue with Hon’ble KERC to ensure that BESCOM takes

appropriate steps to improve the voltage profile.

A Task Force could be set up on urgent basis to identifying the issues (Low voltages, high MVAR

drawal, strengthening of transmission & distribution system, drawal capability of Bengaluru area ,

reactive requirement at DISCOMs etc) and to finalize the action plan to resolve these issues in a

time bound manner.


3. UV RELAYS

In the Special Meeting held on 26.04.20116, KPTCL had informed that the UV relay scheme had not

been implemented.The following locations and logics for UVR had been finalized the meeting:

KPTCL: (@ Nelamangala, Somanahalli, Hoody and Bidadi)

Stage 1: When voltage < 380 kV for 10 minutes then the identified loads has to be

disconnected.

Stage 2: When voltage < 370 kV for 5 minutes then at least 25% of additional ICT load has

to be disconnected.

In the 120thOCCM, KPTCL had informed that only for 25 MW automated scheme had been

implemented. Subsequently through manual action the voltages were being controlled. Following

were instances of logic being satisfied during the month of May 2016.

Jan-16 5 0 5 0


SRPC pointed that shut down requests were not being received in time. Many times shut down

proposals for the current month were being requested which needs to be avoided.

SRPC/SRLDC also expressed concern over non-availing of planned shut downs. Reasons for

non-availing the shut downs was also not being furnished. Better planning and execution was

required by all utilities of SR. Number of shut downs were also being taken on emergency.

SLDC agreed to look into the issues and improve the availing percentage and agreed to furnish

the shut down proposals in a timely manner.

12. TRANSFER CAPABILITY DETERMINATION BY STATES

As per 4th NPC Meeting, all states were required to compute monthly ATC/TTC limits for their control

area. Monthly TTC/ATC would be uploaded by SLDCs in their respective websites and also

communicated to concerned RLDC & NLDC subsequently. A workshop had been conducted on

ATC/TTC computations was held on31st March and 1

st April 2016. However, no official from KPTCL,

LD had attended. Dedicated Reliability Group (Study Group) at SLDC was very much required.


SRLDC/SRPC pointed out that dedicated Reliability Group was essential at SLDC to carry out

ATC/TTC computations for the Control Area, day to day contingency analysis, Outage

coordination, PoC computations, Reactive power in STU/DISCOMs/embedded generators etc. It

would be useful in providing operational feedback to STU/CTU/CEA, feedback would be useful in

Planning Process.


SLDC pointed about manpower crunch to take up these activities.

It was suggested that SLDC could take up this issue with Management. SRPC/SRLDC stated that

the Higher Management would once again be apprised of the importance of dedicated reliability

Group.

13. REASONS FOR DEMAND -SUPPLY GAP AND ITS VARIATION

This issue of furnishing the load shedding details in different heads along with the reasons by states

had been taken up in the NPC Meetings. MoP/CEA specifically needed reasons for load shedding like

transmission constraints, distribution constraints, and regulatory constraints viz the power purchase

not allowed beyond an agreed cost or quantum, natural calamities, tripping of some of major

transmission lines etc.


SRPC pointed out that reasons of load shedding under various heads as elaborated above were

required by MoP/CEA. The requirement was informed in earlier OCC Meetings but information in

requisite format was not forthcoming. The exact reason for deficit was to be elicited.

SLDC agreed to furnish the details as required.

14. PATROLLING / MAINTENANCE OF CRITICAL LINES AND SUBSTATIONS

In recent times, insulator tracking has been observed in Transmission lines and Substations located

in the coastal and polluted areas. It is pertinent that Patrolling and Maintenance needs to be carried

out for the critical lines as per Patrolling Guidelines. It is also imperative that switchyards of the

generators located in coastal areas need to be maintained stringently. SRPC vide letter dated

05.05.2016 had communicated to the concerned in this regard. Following lines require special

attention and patrolling and maintenance schedule/carried out needs to be furnished regularly:

400 kV Kaiga-Guttur D/C 400 kV Guttur-JSWEL S/C

400 KV Guttur-HiriyurS/C

400 kV Hiriyur- Nelmanagala 400 kV BTPS- JSWEL S/C 400 kV RTPS-BTPS S/C

400 kV UPClL-Hassan D/C

220 kV Nagjhari- Kodasalli D/C

220 kV Nagjhari- Ambewadi D/C

220 kV Nagjhari- Hubli D/C 220 kV Nagjhari- Bidna/Hublil D/C

220 kV Kadakola-Kanianmpetta S/C


SRLDC/SRPC highlighted significance of timely Patrolling/Maintenance. The Patrolling

Guidelines were required to be followed. This was evident from recent disturbance at Gazuwaka,

Tuticorin, Vallur, Outages in Western Ghats in Karnataka (Kaiga, Nagjhari, Sharavathy, UPCL)

etc. Important elements in Karnataka Control Area which require specific attention had been

brought out and details as sought were required to be furnished.

KPTCL agreed to pass on specific instructions to the field for periodical Patrolling/Maintenance

and regular updates would be furnished. KPTCL will furnish advance maintenance schedule for

the above elementsand appraise the deviation details, if any, in every OCC Meeting.


15. RESTRICTED GOVERNOR MODE OF OPERATION (RGMO)/FGMO OF GENERATING UNITS

15.1 RGMO response was being analyzed in the OCC meetings and inadequate response was an

area of concern and there was no noticeable improvement. SLDCs were to analyze RGMO

instances posted by SRLDC for generators in their control area and initiate suitable action

as per orders in respect of 84/MP/2015. Inadequate Response was to be taken up with

SERC (Petition No.302/MP/2013).

15.2 SLDCs/RLDCs to analyse response of generators during major frequency excursions and submit

report on quarterly basis to SERCs and POSOCO. The following also needed to be taken

note of

Oil support, if required, for grid security needs to be resorted

Taking out RGMO/FGMO, without informing SLDC/SRLDC may be liable to action under

Section 142 of Act.

Units should not be allowed to operate with their valves wide open and ensure RGMO

performance at all levels of generation.

Any willful locking of the Governors, poor and reverse response, introduction of more than

mandated dead band or any other activity to curtail the primary response, will be viewed

seriously and action under Section 142 of Act shall be taken against such generators for

non-compliance of the provisions of the Grid Code

15.3 RLDCs/SLDCs have inherent powers to restrict schedule corresponding to 100% of installed

capacity without wide valve open condition, even at part loads ensuring primary governor

response at all stages. It was reiterated that unit should not be scheduled beyond 100% of MCR

rating. In view of CERC Order w.r.t Petition No.302/MP/2013, SLDCs need to restrict the state

generators schedule suitably.

15.4 RGMO status of State generating station to SRLDC through ICCP for RTPS, UPCL and JSWEL

not mapped.


SRLDC/SRPC informed that TSSLDC had taken up the non-performance of embedded

generators with their SERC. IEGC and CERC Orders provides for significant steps to be taken by

SLDC in achieving RGMO compliance.

SLDC, KPTCL shall ensure mapping of RGMO status of all eligible generating units in the state

within this month.

SLDC KPTCL will initiate action for appraising on past performance of RGMO of Generating units

in the state to KERC. Also will ensure RGMO performance analysis of future instances and take

suitable action as required.


16. LOW VOLTAGE RIDE THROUGH (LVRT)/PROVISIONS OF CEA REGULATIONS IN RESPECT OF

RENEWABLES

The 3rd

meeting ha been scheduled for 5th July 2016 in Chennai. Nodal officer nomination was

pending from SLDC. Information sought as per Format A& B has not been furnished. There

was on reported update on other issues also.


SLDC agreed to furnish the Nodal Officers details within a weeks’ time. Details sought as per

Format A& B were being compiled in discussion with Wind Developers.

SRPC/SRLDC pointed out that there were number of actionable points to be taken to comply

CERC Order and as finalized in the two special meetings and requested KPTCL to take concrete

steps. Participation of SLDC in 3rd

meeting at Chennai was vital. Ensuring strict implementation

of LVRT feature and other CEA/CERC requirements in all upcoming / newly getting connected

Wind / Solar generators was to followed diligently. Same may be certified while furnishing the

monthly RE generation addition report.

KPTCL informed that they were ensuring LVRT provision and only temporary connectivity was

being granted along-with some penal clauses. Subsequently, after meeting technical specification

specified, permanent connectivity was granted. SRLDC/SRPC suggested for ensuing all the

technical requirements before issuing any type of connectivity.

17. DEMAND ESTIMATION FOR OPERATIONAL PURPOSE (CLAUSE 5.3 OF IEGC)

Each SLDC was to create a mechanism and facilities to facilitate on-line demand estimation of

demandfor daily operational purpose for each 15 minutes block by 01.01.2011. It was required for

Ancillary Services (AS4), RSD/TM schedules etc also.


SRLDC/SRPC enumerated the need for the Requirement and Availability forecast, which was

also a Regulatory requirement.

SLDC agreed to further streamline the process with immediate effect

18. SPS LOADS FOR KKNPP UNIT II

174 MW of loads to be identified and implemented.


KPTCL informed that they had identified the loads in Hassan area and exact details would be

furnished.

PGCIL stated that they would coordinate with the state utilities for extension of the signal to the

STUs.

Synchronisation of KKNP # 2 is expected by July’16 and thereby KPTCL& PGCIL shall ensure

implementation of SPS well on time.

19. INSTANTANEOUS SCHEME FOR SUDDEN WITHDRAWAL OF WIND


Like Tamil Nadu, KPTCL also needs to firm up a scheme for sudden withdrawal of Wind generation.


SRLDC /SRPC explained need for Instantaneous Scheme to take care of sudden withdrawal of

wind generation and it assumed significance as Karnataka was having around 3,000 MW of wind

generation. KPTCL need to focus on Substations having maximum ingress of wind generation.

KPTCL informed that a Consultant has been selected to look into various aspects of

Wind/Renewable integration. They would endeavor to include this aspect if already not covered in

the scope and would come with a scheme. KPTCL will revert back with the details of action /

status by next month

20. PHASE-I & PHASE-II ACTIVITIES IDENTIFIED IN PROTECTION AUDIT

Phase- I& Phase-II activities identified in Protection Audit need to be completed in a time bound

manner. As per Order dated 18.08.2015 on Petition No. 374/MP/2014 extension up to 15.01.2016

had been allowed. KPTCL filed a separate application before CERC on 07.01.2016 seeking time

extension up to 31.05.2017, and the same is under consideration by CERC.


KPTCL informed that LOI had been placed on M/s Alstom after necessary approvals for PSDF

funding with the completion schedule of March 2017. The Tripartite agreement has been signed

by MD, KPTCL and has been put up to Energy Department, GoK for necessary signatures.

Extension from Hon’ble CERC upto May 2017 was awaited.

21. UPDATE ON ACTIONABLE POINTS IN RESPECT OF BMRCL

To expedite on actionable points of KPTCL/BMRCL which were finalized in the special meeting: Report of BMRCL on 17

th& 21

st December 2015 incidents

Relays and settings at BMRCL needed to be reviewed, tested and verified

SLDC stated they would follow up the recommendations. SRLDC clarified that the tap changing is reviewed

periodically and there by timely implementation is very relevant and requested to SLDC, KPTCL to co-

ordinate accordingly.

23. OVERLOADING OF THE TRANSMISSION ELEMENTS

Line loading on 400 kV Gooty – Nelamangala, Gooty –Somanahalli & Hiriyur-Nelamangala lines

had gone very high failing to satisfy N-1 criteria

N-1 violation of MysoreICTs

Rectification of Hoody ICT and maintenance of healthy spares.


KPTCL informed that the 3rd

ICT at Mysore would come up shortly. One phase (R ph) of 167

MVA capacity of ICT- II (Failed) would come by July 2016 and the ICT was planned to be

restored by August 2016. ICT-I issue of foot insulation have been temporarily taken care, and the

rectification works would be taken up after ICT-II comes back (after monsoon).

SRLDC/SRPC suggested SLDC to take appropriate steps to avoid overloading of the lines and

ICTs as given above. SLDC proactively needs to control the loading and specific instructions by

SRLDC need to complied immediately. Action on maintaining the spares specifically at important

nodes (like Hoody) needs to be given utmost importance.

24. ISSUES TO BE TAKEN UP WITH SERC

24.1. Roadmap to Operationalize Reserves in the Country

Hon’ble CERC vide Order dated 13.10.2015 on Petition No. 11/SM/2015 in the matter of Roadmap


to operationalize Reserves in the country had directed as follows:

(b) The Commission reiterates the need for mandating Primary Reserves as well as Automatic

Generation Control (AGC) for enabling Secondary Reserves.

(i) All generating stations that are regional entities must plan to operationalize AGC along with

reliable telemetry and communication by 1st

April, 2017. This would entail a one-time expense for

the generators to install requisite software and firmware, which could be compensated for.

Communication infrastructure must be planned by the CTU and developed in parallel, in a cost-

effective manner.

(ii) On the other hand, National/Regional/State Load Dispatch Centres (NLDC/RLDCs/SLDCs)

would need technical upgrades as well as operational procedures to be able to send

automated signals to these generators. NLDC /RLDCs and SLDCs should plan to be ready

with requisite software and procedures by the same date.

(iii) The Central Commission advises the State Commissions to issue orders for intra-state

generators in line with this timeline as AGC is essential for reliable operation of India’s large

inter-connected grid.

(c) To start with, a regulated framework in line with the Ancillary Services Regulations would need

be evolved for identification and utilizing of spinning reserves and implemented with effect from 1st

April, 2016. This framework may continue till 31st

March, 2017.

……………

(d) In the long term, however, a market based framework is required for efficient provision of

secondary reserves from all generators across the country. For this, NLDC/POSOCO is directed to

commission a detailed study through a consultant and suggest a proposal to the Commission for

implementation by 1st April, 2017, giving due consideration to the experience gained in the

implementation of Spinning Reserves w.e.f. 1st April, 2016.

24.2. Framework on Scheduling and Imbalance Handling for Variable Renewable Energy Sources (Wind and Solar)

24.3. Compliance of the Central Electricity Authority (Technical Standards for Grid Connectivity) (Amendment) Regulations, 2013 by new generating units being commissioned and getting connected to the grid.

Para 63 of Order in Petition No. 420/MP/2014 66

63. As the Central Electricity Authority (Technical Standards for Grid Connectivity)(Amendment) Regulations, 2013 is applicable for wind generating stations and generating stations using inverters and are connecting at voltage level 66 kV and above to the grid after 15.4.2014. Therefore, all the wind generating stations are directed to comply with the provisions of CEA Technical Standards for Connectivity Regulations. We further direct CTU and STUs to make provisions in this regard in their Connection Agreements to ensure that wind energy generators comply with the provisions of CEA Technical Standards for Connectivity Regulations for grid connectivity before granting connectivity to the grid.

Deliberations in the meeting

KPTCL/SLDC took note of the Regulatory/Technical mandatory requirements.

KPTCL/SLDC informed that Framework on Scheduling and Imbalance Handling for Variable

Renewable Energy Sources has been notified by KERC few days back, which was to be

implemented within 3 months. SRPC/SRLDC requested SLDC to share the highlights in the next

OCCM.
