OPGW link for Salal and Tanakpur Power stations was commissioned by POWEGRID in May 2016. He, however, mentioned that links of Salal and Tanakpur were not functioning properly since commissioning. Link of Salal Power Station was restored on 11.07.2016 but that of Tanakpur was down till that date. Representative of POWERGRID informed that OPGW links for Chamera-I, Chamera-II, Dhauliganga and Tanakpur were commissioned. He assured that OPGW for connecting Chamera-III HEP and URI-I HEP would be commissioned by 15.08.2016. The work of OPGW connectivity to Uri-II was pending due to severe ROW issue. He further informed that OPGW connectivity at Dulhasti HEP would be achieved along with commissioning of second Line between Dulhasti and Kishanpur. (B) Representative of NHPC stated that in the 7th

TeST subcommittee meeting held in January 2016, it was agreed by POWERGRID to connect the existing cable between Chamera-I to Sewa-II with the terminal equipment for the wideband connectivity. He added that though Chamera-I OPGW had been made operational on 11.07.2016, OPGW for Sewa-II had still not been made operational.

After deliberations, it emerged that there are issues about scope of work to be carried out by POWERGRID and NHPC and it was decided that they would hold a separate meeting to resolve the issue of OPGW connectivity of SEWA-II. (C) Representative of NHPC desired to know status of optical Fiber connectivity of

Bairasiul HEP. Representative of POWERGRID informed that work for Bairasiul had already started and out of 96 kms link, work on 14 km stretch had been completed. The work would be completed in next 3-4 months. In response to query regarding OPGW to Parbati-III

HEP, POWERGRID informed that OPGW for Parbati-III had not been included in their present Plan. 2.1.3 Implementation of OPGW and OLTEs under Package-V

Representative of HPSEBL informed that OPGW of about 360.91 Km was to be laid on HPSEBL transmission network under package-V. Schedule of laying OPGW on HPSEBL network had been received from NR-II, POWERGRID. However, installation schedule in respect of OLTEs had not been intimated. HPSEB requested POWERGRID to update the latest status for implementation of OLTEs. POWERGRID informed that for communication equipment (OLTE) for HPSEBL would be supplied by Oct/Nov this year and all links under this package would be commissioned progressively from Dec’ 2016 to completion target for this package i.e. March’ 2017.

2.1.4 Implementation of OPGW under Package-I (a)

Representative of HPSEBL informed that OPGW of about 515.189 Km was to be laid on HPSEBL transmission network under package-I (a). During 7th

Test sub-committee meeting held in January 2016, it was informed by POWERGRID that LoA for additional OPGW had been placed. With regard to communication related equipments, the scope had been split in two packages and LoA for both the package would be placed soon. HPSEBL requested POWERGRID to update the latest status for implementation of OPGW.

Representative of POWERGRID informed that M/s FIBCOM India Ltd was the Supply & Erection contractors for SDH & DCPS terminal equipment under Package- IV(a). LOA date: 16.05.2016 and Completion schedule: 18 months. Site Survey by contractor of HPSEBL sub-stations was in progress.

Site Survey by contractor of HPSEBL sub-stations was in progress.

2.1.5 Additional OPGW requirement for Solan-Kunihar (20 Km) under Package I (a)

Representative of HPSEBL informed that POWERGRID Telecom department had laid OPGW on Solan-Kunihar (22 Km) transmission line of HPSEBL and POWERGRID was to provide 02 Nos. E1 ports (2 Mbps) for HPSEBL communication purpose at Solan&Kunihar Sub-Station. Further, under additional package I (a) OPGW (24 fibers) of about 515.189 Km is to be laid on HPSEBL transmission network by POWERGRID. Giri HEP, 132 kV Sub-Station, Poanta& 132 kV Sub-Station, Kala-Amb up to 132 kV Sub-Station, Solan are to be connected through OPGW under Package I (a). If OPGW connectivity of said Sub-Stations/Power Houses from Solan to Kunihar is achieved by

HPSEBL using telecom network of POWERGRID, 22 fibers of said OPGW link i.e. Poanta-Kala-Amb-Giri-Solan would become out of OPGW connectivity & remain unutilized. In order to make dedicated OPGW connectivity for HPSEBL network and further to utilize the OPGW to large extent, he requested OPGW to be laid on Solan-Kunihar (20 Km) transmission line. Representative of POWERGRID informed that this package was being implemented by their NR-II office at Jammu and all required amendments would be issued by them only. He requested HPSEBL to directly be take up this issue with POWERGRID (NR-II) Jammu office. SE, NRPC requested that if this link is required by HPSEBL, this link may be included in ULDC network. POWERGRID agreed to consider this proposal.

2.1.6 Tejas make Fibre Optic equipments installed under Central Sector at SLDC, Shimla, 220 kV Sub-Station, Kangoo (Gagal) Sub-LDC Hamirpur&Kunihar.

Representative of HPSEBL informed that ECI Telecom equipment at 220 kV Sub-Stations Kangoo & Sub-LDC Hamirpur are to be connected with recently installed Tejas make Fiber Optical equipments through local patching. It was, therefore, requested that necessary cards required for local patching for Tejas OLTE at SLDC, Shimla, 220 kV Sub-Station, Kangoo (Gagal) and Sub-LDC Hamirpur should be arranged by POWERGRID. Necessary expenditure for procurement of cards would be paid by HPSEBL to POWERGRID on actual basis. Representative of POWERGRID informed that they had already considered these requirements in the provisions of Tejas package and required patching shall be done with installation of ECI equipment.

2.1.7 OPGW (12 fibers) laid over HPSEBL Transmission Network under ULDC phase-I Project

Representative of HPSEB informed that HPSEB in co-ordination with POWERGRID had established OPGW (12 Fibers) Network on its following transmission lines Under ULDC Phase-I Scheme of Northern Region.

Transmission Line OPGW Length

132 kV Hamirpur-Kangoo (D/C) = 43.780 Km 132 Kangoo-Kunihar (D/C) = 50.240 Km 132 kV Jutogh-Kunihar (S/C) = 15.340 Km

Total = 109.36 Km

OPGW laid over 132 kV Kangoo-Kunihar transmission line got broken on 11.05.2016. Further, while making the joint of broken portion; it was found during splicing by vendor (in the presence of Sr. Engineer of POWERGRID Telecom department) that tube-1 &

tube-2 of broken OPGW carries 07 Nos. fiber each and same was confirmed telephonically by Sh. Rajesh Chaudhary, Sr. Engineer (Telecom), POWERGRID, Kumar House, Shimla-171004. HPSEBL requested POWERGRID to look into the matter and if extra fiber is available in tube-1 & tube-2, same may be connected with entire OPGW (109.36 Km) network of HPSEBL, so that benefit of these additional 02 No. fiber could be availed by HPSEBL. Representative of POWERGRID informed that there was no extra fibre available on above mentioned links, and above said additional fibers were only dummy fiber with different property and cannot be used for HPSEBL purpose.

2.1.8 FO connectivity between the stations where OPGW has been laid with BBMB

SLDC Chandigarh Representative of BBMB informed that the matter regarding expeditious establishment of FO connectivity between the stations where OPGW has been laid with BBMB SLDC Chandigarh had been taken up with POWERGRID at various forums. In the 6th TeST subcommittee meeting held on 10.09.2015, it was stated by POWERGRID that the work of establishment of FO connectivity between the stations where OPGW has been laid with BBMB SLDC Chandigarh would be completed by November, 2015. However, in the 7th

TeST sub-committee meeting held on January 2016, it was intimated by POWERGRID that this activity would be completed by March 2016. The following activities were yet to be attended:

a) SAT for terminal equipment was pending at BBMB SLDC Chandigarh and various other sites of BBMB. One no. EDFA card installed in the SDH panel at BBMB Chandigarh became defective in Nov. 15 and the same needs to be replaced by the firm at the earliest. Also, one no. EDFA card installed at SDH Panel at BBMB Ganguwal site also needed to be replaced. Representative of POWERGRID informed that they were ready for SAT any time, and BBMB may fix a date for start of SAT. After discussion it was decided that SAT would be started from 2nd

Aug’ 2017 with one EDFA. As required by BBMB, POWERGRID confirmed that their representative would be available at site for SAT

b) Representative of BBMB stated that the matter regarding connectivity of Sangrur, Barnala, Delhi (RR) & Narela sites of BBMB with SLDC Chandigarh, has been regularly taken up with POWERGRID. In the 7th meeting of TeST subcommittee

held in January 2016, it was intimated by POWERGRID that the works would be completed by March’16. He further intimated that the matter regarding laying of approach cable between BBMB Barnala & PSEB Barnala (approx. distance 450 m) had been taken up with POWERGRID under “Additional OPGW connectivity in NR under FO expansion Project – ULDC Phase-II – OPGW Package 1 (a)”. He requested POWERGRID to expedite this work and ensure that other associated work at intermediate sites is completed at the earliest, so that connectivity of Sangrur & Barnala with BBMB SLDC Chandigarh is ensured.

Representative of POWERGRID informed that faulty EDFA card will be replaced shortly.

c) Representative of BBMB requested POWERGRID to provide the time schedule for ensuring the connectivity of Delhi (RR) & Narela BBMB sites with BBMB SLDC Chandigarh.

As regards Malerkotla, he stated that this was an additional requirement and amendment was being issued shortly and equipment would be supplied after that.

2.1.9 Pending OPGW installation on UPPTCL sites Representative of POWERGRID informed that 3-4Kms OPGW installation on each of 220kV Muradnagar-Sahibabad and 220 kV Muradnagar-Loni lines was pending since 4 months due to non-availability of shutdown by UPPTCL. These links were very critical for further connectivity with Noida. He requested UPPTCL to provide shutdown on both the links. SE, NRPC requested UPPTCL for take the matter with their higher management for shutdown of these lines. Representative of UPPTCL informed that the matter had been discussed with higher management several times but due to criticality of Noida load, shutdown could not be arranged. He confirmed that the work would be completed by Sept’ 2016.

He further informed that some towers on two lines of UPPTCL namely Muradabad-C B Ganj and Bareilly-Muradangar fell down 4 months back and tower restoration could not take place till that date. The data of these lines was not being received since 4 months. SE, NRPC stated that long delay in restoration of lines as well as no alternate for telemetry is cause of concern. UPPTCL confirmed that work was going on and might get completed in next 2 months. 2.2 Communication issues 2.2.1 Non Functioning of PLCC panels at URI-II Power Station

Representative of NHPC informed that following works in respect of the PLCC system at URI-II Power Station were still pending:

• Commissioning of PLCC system of URI-I-URI-II line • Replacement of cards of BPL panels at URI-II Power Station (URI-II – Wagoora

Line) • Replacement of Power Supply module of PLCC panel of Channel 2 at Wagoora

end.

Representative of NHPC mentioned that in 7th

TeST subcommittee meeting held in January 2016 (Point No. 2.2.8), POWERGRID had informed that HF cable had been dispatched for Uri-II and would be reaching Wagoora shortly. Visit of BPL Engineer had also been tied up. It was also assured that all PLCC works would be completed by Feb 2016. Representative of NHPC requested POWERGRID to update the status.

Representative of POWERGRID informed that this was a long pending issue. He stated BPL was not giving any services and therefore NHPC may shift their PLCC panels/cards from locations where wideband node is commissioned to faulty card/module locations for resolving the issues. Representative of NHPC informed that PLCC panels were required for other functions even after wideband node commissioning and requested POWERGRID to resolve the PLCC problem at the earliest. POWERGRID agreed to resolve this pending issue by early site visit by BPL engineer . 2.2.2 Tele-protection through communication equipments to be installed on HPSEBL locations under Package-V.

Representative of HPSEB informed that they intend to run Tele-protection through ECI Telecom equipments to be installed on HPSEBL Sub-Stations/Power Houses under package-V. Further, it was intimated by LD&C department of POWERGRID that communication equipment considered under package-V is having E1 port (G.703) and same can be used for interfacing tele-protection. In this regard, he requested that following information may be supplied to HPSEBL:

1. Detail of additional equipments/cards & associated circuitry required for running Tele-protection through ECI Telecom equipments

2. Cost of additional equipments/cards & associated equipments required for

running Tele-protection. 3. Compatibility of Numerical relays/P10relays etc. & other relays for Tele-

protection. 4. How many relays are being supported by 01 No. card for Tele-protection? 5. Firm address/contact detail providing the solution for Tele-Protection.

Representative of POWERGRID informed that they can provide E1 port (G.703) from their ECI make communication equipment and all other works mentioned above can only be carried out by HPSEBL on their own. HPSEBL agreed to resolve this issue on their own.

2.2.3 U.P.’s Requirement of Communication Channels

A. Giving a background, representative of UPPTCL stated that as per Data structure, data of each RTU/SAS is to be provided through dual routes, one route to SLDC main and one route to SLDC backup. In the meeting held between UPPTCL and POWERGRID on 29.1.2014, UPPTCL had requested to provide one channel from RTU to Main SLDC Lucknow and second channel to Backup SLDC for each RTU. POWERGRID had committed to examine the engineering aspect for this requirement. The matter was re-discussed in the meeting of Sub Committee for channel requirement held on 27.6.2016 at NRPC office. In the discussion POWERGRID‘s view was that channels should be dropped at respective Sub LDCs. In the above mentioned background, he requested that communication should be provided to Main & Backup SLDC directly from RTU site through separate channel. Representatives of POWERGRID agreed that data for RTU/SAS is to be provided through dual channel but there appears to be some confusion in UPPTCL about the scheme implementation. Earlier the scheme was planned as mentioned by UPPTCL that, data of all RTUs would come to main SLDC over 1st channel and data of RTUs on 2nd channel would report to backup SLDC. However, during the planning of ULDC Phase-II in the years 2012 & 2013, the design was revised and accordingly it was informed to all SLDCs that due to non-availability of required channels from RTU/SAS stations to Main and Backup SLDCs for direct connectivity, data of all RTU/SAS stations would first report to

nearby SLDC/Sub-LDCs. Accordingly under SCADA/EMS up-gradation package (Siemens contract), required nos. of terminal servers were envisaged in Bill of Quantity (BOQ) for SLDCs and Sub-LDCs at all control centres in Northern Region. Subsequently the scheme was implemented in revised manner.

SE, NRPC requested other SLDCs to offer their observations. Representatives of BBMB clarified that in implemented scheme, data of all RTUs first comes to respective Sub-LDCs then it reports to respective SLDC and backup SLDC. As per earlier envisaged design, failure of any control centre (Main / Backup SLDC) due to any reason would have caused data of all RTUs to be lost from that control centre. But as per revised implemented scheme, if one sub-LDC fails then data of certain RTUs reporting to that particular sub-LDC will only fail and if one control centre fails then data of respective Sub-LDCs would report to other control centre over redundant channel automatically. Thus, revised scheme is more reliable.

After detail discussions, it is concluded that, as sufficient channels are not available from each RTU to Main and Backup control centre, implementation as requested by UPPTCL was not possible as on date. However, with channel availability after implementation of all OPGW packages for Centre and as well as State Sector, the scheme as suggested by UPPTCL can be implemented.

B. Representative of UPPTCL requested POWERGRID to complete the fiber

connectivity to SLDC (NEW), Gomti Nagar from 220 KV Gomtinagar as an alternate route by August, 2016. Representatives of POWERGRID agreed to complete the same by Sept 2016.

2.2.4 Other Communication issues of U.P.

Representatives of UPPTCL informed that i). Following links were unavailable/not working

a) 10 mbps ICCP links between Main SLDC LKO to Backup NRLDC Kolkata. b) 10 mbps ICCP links between backup SLDC Modipuram to backup NRLDC

Kolkata. c) 10 mbps ICCP links between backup SLDC Modipuram to Main NRLDC New

Delhi. d) 10 mbps Share folder links between backup SLDC Modipuram to Main NRLDC

New Delhi. ii). Following links were failing frequently

a) 10 mbps Share folder links between Main SLDC LKO to Main NRLDC New Delhi.

b) 10 mbps ICCP link (Tejas /Telecom) between Main SLDC LKO to Main NRLDC New Delhi.

c) Availability of 100 mbps multisite link is also not satisfactory. Availability of Multisite link for May ‘16& June’16 is 88.3% and 94.8% respectively

Representatives of POWERGRID informed that all channels have been provided to UPPTCL except link from Modipuram (backup SLDC) to Kolkata (backup NRLDC) as links from respective SLDCs to back up NRLDC at Kolkata have been provided by POWERTEL. However, the same was not be possible at Modipuram due to non-availability of POWERTEL links. POWERGRID reassured that joint testing can be done to verify availability for these links. UPPTCL agreed for the same.

Regarding frequent failure of the links on Tejas network, POWERGRID informed that Tejas link was available for 94.8% and rest of the time link was down due to fibre cut on Dadri-Maharanibagh link. NRLDC pointed out that to avoid data failure a redundant path for this link was required. POWERGRID agreed to explore the possibility of providing a redundant path.

2.2.5 Communication plan for channel redundancy and to back-up NRLDC

Representative of NRLDC informed that the Central Sector SASs / RTUs have been planned for dual channel reporting , still some stations are reporting only through single channel as the standby channel is either not provided or not working . NRLDC further informed that some stations reporting directly to NRLDC SCADA system do not have redundant communication channel. Out of total 111 nos stations integrated at NRLDC, 48 stations are connected with redundant optical fibre channel and 32 stations are provided with single optical fibre channel. The telemetry from these stations is stable. However, there are 31 channels on various mediums without redundancy and are plagued with intermittent display. At present, 17 link were working on GPRS either as main or stand-by links. There are 21 stations integrated on PLCC as end mile communication. It was also informed that the GPRS communication was accepted as a temporary solution for telemetry which was still to be replaced with wideband network.

NRLDC pointed out the fact that the fibre cut in Dadri-Maharanibagh section had led to 80% telemetry failure at NRLDC which clearly confirms the requirement of redundant channel with route diversity. A Committee had been formed to prepare the plan for requirement to provide the redundant communication channel. NRLDC requested for a target date for making the redundant channel availability, at least for 400 kV and above stations and major generating stations could be discussed in detail for implementation.

POWERGRID informed that with the implementation of the communication network under installation, all the GPRS system would be replaced with the wideband network. It was also confirmed that the channel planning had already been undertaken for implementation of route diversity which would be implemented in next six months.

The sub-committee decided to form a joint verification team consisting shri S P Singh from NRPLC, KK Jain from POWERGRID along with representative of NRPC (KNM RAO), for the redundant channel availability for all the stations directly reporting to NRLDC. It was also agrred that any faulty channel which had already been configured would be restored on priority basis. A report on the testing would be presented in the next TeST Committee meeting.

2.2.6 Second channel connectivity for all stations

Representatives of DTL requested POWERGRID to provide redundant channel connectivity for all DTL stations. POWERGRID informed that after implementation of state sector OPGW & equipment, redundant channels as sought by DTL would be available.

2.2.7 Implementation of Multisite Configuration

Representative of BBMB informed that the SAT of Multisite functionality was conducted by M/s SIEMENS at BBMB SLDC from 21.12.15 to 24.12.15. However due to non-availability of requisite communication links, only the functionality between BBMB SLDC and Punjab SLDC was tested, while the actual implementation of Multisite configuration was yet to be completed and demonstrated by M/s SIEMENS. Some of the tests contained in the SAT procedure, also could not be conducted due to non-availability of communication links. In the 7th

Meeting of TeST Sub-Committee held in January 2016, POWERGRID had requested to constitute a group to look into the details of communication requirements for Multisite Configuration. In this regard, a group was constituted by NRPC vide letter No. NRPC/OPR/108/04/2016/5328-40 dated 10.06.2016 and the first meeting of the group was held on 27.06.2016.

Representative of BBMB also informed that the implementation of Multisite Configuration between BBMB SLDC and PSTCL SLDC was still pending due to which data of PSTCL was not available at BBMB SLDC. As the finalization and implementation of communication requirements for Multisite was likely to take some more time, BBMB requested that PSTCL data may be provided to BBMB through ICCP link.

Representative of POWERGRID agreed to get the ICCP link configured between PSTCL and BBMB SLDC within one week. 2.2.8 Disposal of old and obsolete SCADA equipment of ULDC Phase - I. A. Representatives of BBMB, HVPNL, PSTCL and DTL stated that the matter regarding disposal of old/obsolete equipment dismantled after commissioning of ULDC Phase – 2 as well as the methodology for its cost adjustment was under discussion since first meetings of TeST sub-committee. It was informed by POWERGRID that they had filed a petition in CERC on the matter. In the 7th Meeting of TeST Sub-Committee held in

January 2016, it was decided that the matter could be taken up in next NRPC meeting so that a consensus could be evolved and CERC may be apprised accordingly

Representative of BBMB stated that they were facing severe space constraints at BBMB SLDC and there was no space available at BBMB SLDC to install the equipment being supplied by POWERGRID under URTDSM Project. BBMB requested POWERGRID to facilitate early disposal of obsolete SCADA equipment of ULDC Phase – I, so that the URTDSM equipment could be installed. POWERGRID informed that there had been lot of discussion on this issue in all TeST meetings since beginning and number of issues were there in disposal of old and obsolete equipment as RRVPNL along with their DISCOMS have objected and submitted an affidavit mentioning that CERC have no Jurisdiction to decide on the matter of accelerated depreciation. Matter had been discussed with RRVPNL officials but they had not withdrawn the affidavit till that date. No participant of RVPNL was present in the meeting. Representative of POWERGRID suggested that it was better to wait for July’ 2017, the date on which all payment would be recovered for ULDC phase-I. POWERGRID requested BBMB to make some alternate arrangement to store the obsolete equipment of ULDC Phase – I till the recovery of charges gets completed in 2017. B. This Issue is covered in 2.2.8A 2.2.9 EPABX system A. Representative of BBMB informed that the EPABX System was received at BBMB SLDC in April, 2015. However, the installation of EPABX System was incomplete till that date. The integration of existing PUNCOM exchanges installed at BBMB Sub-LDC with new EPABX was still to be carried out by the firm. The work of wiring and installation of telephone cables & sets etc., at all BBMB Sub-Stations and Power Houses was yet to be carried out and connectivity to BBMB Sub-Stations/Power Houses was yet to be established through new EPABX. He mentioned that without any connectivity to Power Houses/Sub-Stations, the new EPABX System would not serve any purpose for SLDCs.

Representative of BBMB pointed out that the matter was discussed in the 6th meeting of TeST subcommittee also, wherein POWERGRID had intimated that this work was to be carried out by the constituents themselves. He, however, opined that as per the provisions of the contract awarded by POWERGRID, all these works were clearly covered in the scope of vendor. In the 7th Meeting of TeST sub-committee, POWERGRID was requested to intimate the relevant provisions of the specifications under which this work was to be carried out by the constituents. However, no communication was received in this regard. Representative of BBMB requested POWERGRID to get the existing PUNCOM make EPABX systems integrated with the new EPABX or intimate the relevant provisions of the contract under which the connectivity to Sub-Stations and Power Houses is to be carried out by constituents themselves.

Representative of POWERGRID informed that this matter had been discussed in detail during 7th

TeST meeting held on April 2016. He informed that new EPABX system was compatible with PUNCON make EPBAX and this aspect has been testes at SLDC Chandigarh. He, however, mentioned that software up-gradation is required for PUNCOM system which is beyond the scope of vendor. If PUNCOM software is upgraded by BBMB, POWERGRID was ready to integrate the new EPABX system with PUNCOM EPBAX. He also pointed out that the useful life of PUNCOM system would be over by end of 2017, so it may not be desirable to invest on this equipment. ON the issue of installation of phones at various sub-stations and power house, representative of POWERGRID informed that in the original scope, total requirement of phones was 103 and installation time given to vendor was 4 to 6 months. Subsequently, the quantity was increased to 3000 all over India and thereafter vendor have declined to carry out this work. Matter has been discussed within POWERGRID and it was decided that it was not feasible to force any vendor for this work with vast geographical area with same rate and term and conditions. Accordingly, POWERGRID have installed phones at their sub-station and centre sector stations on their own and requested to all constituents to install their quantity with their own staff.

BBMB however maintained that as per the provisions of the contract awarded by POWERGRID to M/s Orange, the work of integration of existing PUNCOM exchanges with new EPABX System and installation of telephones at all Sub-Stations and Power Houses was clearly covered in the scope of the vendor. BBMB stated that under the circumstances it was not possible for them to arrange/procure the requisite material and technical knowhow to execute the remaining EPABX work viz integration of old EPABX and installation of telephones at Power Houses and Sub-Stations. After deliberations BBMB expressed intention to take up the issue in the next NRPC meeting. B. Covered in item A above.

2.2.10 ICCP links on Tejas network

Representative of PSTCL stated that POWERGRID vide e-mail dated 14/7/16 had intimated that NRLDC (Siemens Team) had shifted all ICCP links on Tejas network from existing secondary ICCP link (POWERTEL). He, however, stated that the said link was still having issues, as was checked on 15/7/16. PSTCL requested POWERGRID to intimate the current status

POWERGRID informed that till that date, the ICCP links had not been shifted from POWERTEL to Tejas link (new ULDC link). Only VCS links were shifted to Tejas network. This was noted by members.

2.3 AMC issues

2.3.1 AMC for old RTUs

a) Representative of NHPC recalled that in the 7thTeST subcommittee meeting (Point No. 2.3.6), POWERGRID had informed advised concerned station to take over the maintenance activity of the RTUs as the same would be discontinued after the expiry of the present AMC Contract. Representatives of NHPC and NTPC had requested POWERGRID to convey this issue to their higher management for necessary action through written communication and as an agenda in next NRPC meeting, which was agreed by POWERGRID. Representative of NHPC stated that no written communication had been received by NHPC management till date. Further, the agenda was not brought in the 33rd TCC and 37th

NRPC meetings.

Representative of POWERGRID informed that letters had been issued by their higher management to higher management of all constituents. He requested members to take up the matter with higher management for procurement of new RTUs. Members agreed to take necessary action. b) AMC of old RTUs

Representative of DTL stated that AMC of old RTUs had expired on 30.06.16 and requested POWERGRID to extend the same. Representative of POWERGRID informed that AMC would be extended till March 2017 and requested DTL to take necessary action for the replacement of obsolete RTUs. c) Procurement of New RTUs Covered in a) above.

2.3.2 Performance Bank Guarantee for AMC of SCADA/EMS System Representative of BBMB informed that the Performance Bank Guarantees submitted by M/s SIEMENS were scrutinized and it was found that the contact numbers, email & addresses of the signatories were missing in the PBG issued by HDFC Bank. Similarly, the POA Nos. of the signatories were not mentioned in the PBG issued by the Credit Agricole Bank. Accordingly, BBMB had taken up the matter vide letter No. 2235/LD/G-137 dated 16.05.2016. Till that date there was no reply from POWERGRID.

Representative of POWERGRID informed that reply letter would be sent in due course, however these things are not mandatory. He informed that POWERGRID accepts bank guarantees from contractors without above details.

2.3.3 AMC of SCADA / EMS equipment’s

Representative of HVPNL informed that a meeting was held to review / Discuses the pending issues on 28 & 29/01/2016 at POWERGRID, Katwaria Sarai, and New Delhi, wherein the matter of warranty period / AMC was deliberated and it was decided that AMC would commence after the date of approval of all the documents required for the maintenance. He mentioned that subsequently M/s. Siemens vide it’s office Memo No: SG EA/HO/NRLDC/HO/719 dated 05.05.2016 had informed that warranty period had started from 01.01.2016, which is not in line with the above decision taken on dated 29.01.2016 during the meeting. He requested POWERGRID to clarify regarding the date of commencement of aforesaid AMC to avoid any complication at later stage.

Representative of POWERGRID informed that as discussed with all constituents during the said meeting on 28-29th

Jan’2016, AMC has commenced from 01.04.2016 for SCADA/EMS System of SLDCs of Northern Region under ULDC Phase-II.

2.3.4 Balance payment towards AMC Representative of POWERGRID informed that Balance payments for AMC was to be received from follows constituents:

PSTCL : approx 20.98 Lac (Wideband, OPGW, Insurance) DTL : approx 31.56 Lac (OPGW, Wideband & Insurance) PTCUL : approx 2.0 Lac (RTU, OPGW, APS)

He requested that those making payment should intimate in writing the payment details including TDS to POWERGRID for reconciliation. Representatives of PSTCL and DTL assured that they would release balance payments at an early date. No representative from PTCUL attended this meeting.

3.1 Operational issues in EMS / SCADA system 3.1.1 Proper database modeling

Representative of NRLDC informed that except for BBMB central database folder

connectivity had been implemented for all the control centres for exchanging the “change log” file for database synchronization. This could not be done for BBMB due to non-

3.0 Issues in Unified Load Dispatch & Communication scheme of NR (Phase-II):

availability of communication channel. The database synchronization was completed twice successfully. However, the following difficulties were being faced during database modification and synchronization process:

i. The change log files are sent without mentioning and details of the changes made leading to difficulties in sync process as the changes are not known at the time of sync.

ii. The models are not being prepared correctly i.e. elements are not being modeled. Only SCADA points are modeled as the SCADA telemetry does not need modeling of element.

iii. All the element available in the stations are not modeled

iv. Changes are done in the model after sync without information to the other control centre leading to data mismatch and ICCP point mismatch.

v. Display changes are not shared leading to mismatch and non-availability of new element.

He proposed following: i. A separate file may be shared indicating the changes incorporated in the

associated change log file

ii. All database coordinators should verify the availability of all elements in the model and new element if found should be incorporated irrespective of availability of telemetry.

iii. All major changes done after sync process should immediately be informed to all. The information may be shared either through a webgroup specifically created for database coordinators or through WhatsApp group. Thus, information should be passed immediately for incorporation at the appropriate control centre.

iv. Similarly, all changes in the displays, particularly at 220 kV and above, should also be shared immediately to maintain uniformity.

v. The database models must be corrected with proper connectivity otherwise, it is very difficult to maintain the State Estimator model and its performance. A plan should be prepared by each constituent to verify the correction station wise and confirm to NRLDC / NRPC.

After detailed deliberations, the proposal of NRLDC was accepted.

3.1.2 Monitoring of UFR, df/dt and SPS feeder in SCADA

Representative of NRLDC informed that Hon’ble Central Electricity Regulatory Commission (CERC), through its order dated 23rd December 2013 in petition no 221/MP/2012 has ordered as follows:

“(c) UFRs and df/dt relays also be mapped on the SCADA system of each state so that they can be monitored from SLDC/NRLDC. (d) All STUs and SLDCs to map/network the UFR and df/dt on their SCADA system.”

The issue was being discussed in various OCC meetings since then, wherein it had also been decided that both digital and analog values, of the feeders where such relays have been installed, would be monitored by SLDC/NRLDC. PSTCL, HVPNL, HPSEB and DTL informed that they have already implemented the UFR and df/dt displays in their respective SCADA. All other constituents were requested to comply with the direction of Hon’ble CERC at the earliest. NRLDC also observed that the display should be prepared indicating the feeders for different UFR stages separately so that operator is aware about the available quantum of load available for shedding at different stages of UFR operation. All the Constituents were requested to prepare the displays accordingly. Members agreed to comply. NRLDC also requested SLDCs to prepare a display for the SPS which should contain the feeders included in the SPS scheme along with the real time load on those feeders.

3.1.3 Running of State Estimator

Representative of NRLDC stated that the state Estimator was running at NRLDC with acceptable performance. As per the decision taken along with all the constituents, the model being maintained for the State Estimator is different at SLDCs and the models are being modified locally as per the requirement of the local control centre Representative of NRLDC informed that models are being tuned accordingly changes are being done in database models at NRLDC on daily basis. As per agreed policy, the EMS database were not being synchronized as different models are being maintained at Constituent level. However, BBMB pointed out that the NRLDC models should be made available so that the changes are also available at constituent’s end. It was clarified that the model as it is, cannot be imported such this might cause failure of the State Estimator. However, it was decided that the model of NRLDC would be sent on monthly basis and Constituents, would import the same based on their requirements and tune their respective EMS model. NRLDC requested all the members to define “phi”, the bus angle for the voltages so that the same could be displayed in SCADA and could be compared with PMU data which was agreed by all the members.

NRLDC also informed that the following ICTs had sign convention problem which was causing problem in SE solution and requested members to take necessary action to resolve sign convention problem.

• Panipat 400/220 (BBMB) • Akal 400/220, Alwar 400/220, Deedwana 400/220, Anta 765/400, Phagi

765/400 (RRVPNL) • Mukhtsar 400/220 (PSTCL) • Aligarh 400/220, Anpara C 765/400, AnparaD 765/400, Unnao 400/220

(UPPTCL)

Members agreed to resolve sign convention issues. NRLDC informed the following regarding VCS Link Issue:

• Communication link had been provided from Telecom network for the VCS system.

These links were normally kept idle and used only when there was requirement of video conferencing. It was observed that all the links were not available when it was required.

• It was proposed to have a daily monitoring for these links so that the failure was known in advance and alternate arrangement could be made in such case. It was also proposed to shift the VCS system on Tejas communication network once all the links are available on reliable basis and proper monitoring is in place.

Representative POWERGRID informed that all VCS links had been shifted to Tejas network. 3.1.4 SCADA/EMS related common Issues at SLDCs Representative of POWERGRID mentioned following SCADA/EMS related common Issues at SLDCs”

i) Some Constituents had connected external devices with SCADA LAN. ii) Terminal Servers were frequently restarted by switching off the equipment, which

affects the life of equipment iii) External Storage device were connected to system causing threat to security iv) Maintenance of server / battery room temperature at 23-25 degree centigrade and

dust free environment was required.

POWERGRID requested the constituents to resolve above issues otherwise same might impact the warranty of the system installed under SCADA/EMS scheme. Members agreed to take care of issues pointed out by POWERGRID. 3.1.5 State Specific Issues

Representative of POWERGRID informed the following State Specific Issues:

a) J&K PDD: Procurement of broadband connection with static IP at SLDC, Jammu and 20 nos of

data enabled SIM cards for RTU sites to enable reporting of these RTUs at Gladani SLDC as a standby channel. The issue could not be deliberated as no representative of PDD, J&K was not present in this meeting.

b) UPPTCL:

New control centre building readiness at Gomti Nagar was not ready and this was delaying the contract closing of SCADA works.

Representative of UPPTCL informed that control room would be ready by next 15-20 days and requested POWERGRID to start the shifting activity immediately. POWERGRID confirmed the same and requested to inform the readiness of building at least 10 days in advance, so that deployment of manpower can be planned.

3.2 Date of Commercial Operation of “Expansion of Unified Load Dispatch System Centre scheme of NR (Phase-II) . Representative of BBMB stated that the SCADA/EMS System installed at various SLDCs of Northern Region and NRLDC had been replaced/upgraded by POWERGRID under ULDC Phase – II Scheme .The latest status of all the pending issues in respect of BBMB SLDC was intimated to POWERGRID vide this office letters dated 16.05.2016 and 31.05.2016 with a request to advise M/s SIEMENS to resolve all pending issues in a time bound manner. However, M/s SIEMENS vide email dated 01.06.2016 had intimated that they would not extend Manpower support at BBMB in case the AMC report was not signed by EOD on that day. POWERGRID vide their email dated 02.06.2016 had intimated that AMC issues were to be resolved with SIEMENS and POWERGRID had no role in this regard. During the meeting held on 09.06.2016 at BBMB SLDC, M/s SIEMENS agreed to resolve all the issues pending on their part within a period of one month. However, M/s SIEMENS expressed their inability to take any action in respect of the issues pending on the part of POWERGRID. Pursuant to the above, some of the pending issues had been resolved by M/s SIEMENS, while some other were still pending. The gist of important pending issues at BBMB SLDC were submitted.

Representative of POWERGRID informed that all the variances for SCADA/EMS works had been closed at all control centres except 9 nos of variances under EMS in BBMB which as per vendor were beyond scope. However, POWERGRID/NRLDC was working on it and final conclusion would be shared with BBMB shortly. Further POWERGRID informed that during the operation of new SCADA, various issues came up and would be closed in time bound manner in AMC period.

Representative of POWERGRID also informed that as discussed with all constituents during the meeting on 28-29th

Jan’2016, AMC had started from 01.04.2016 for SCADA/EMS System of SLDCs of Northern Region under ULDC Phase-II in all control centres.

However, representative of BBMB objected and contended that lot of variances with reference to contractual requirements in SIEMENS SCADA/EMS were still pending and M/s SIEMENS expressed their inability to take any action in respect of the issues pending. In view of the above, BBMB requested POWERGRID to get all the pending issues resolved in a time bound manner. It was further requested that the Date of Commercial Operation (DOCO) should be deferred till the time all pending issues are resolved by the vendor. He also opined that before notifying the Date of Commercial Operation, the consent of all the constituents should be taken, as the payment of Annual Maintenance Charges (AMC), which would commence after notification of DOCO, was to be borne by the respective constituents. Any non compliance on this issue by POWERGRID may be discussed in next NRPC meeting. POWERGRID informed that AMC had started from 01.04.2016 for SCADA/EMS System of SLDCs of Northern Region under ULDC Phase-II in all control centres.

3.3 SCADA Issues raised by State SLDCs

Before taking up the specific issues, SE(O) NRPC requested all constituents to avoid repeated reporting of closed issues which were not in the provisions of the specifications of contract. They may raise pending issues as per contract/ Specific requirement with POWERGRID first to resolve mutually. Only those non- complied/ unresolved major issues by POWERGRID/ SIEMENS even after regular pursuance may be reported to NRPC secretariat for discussion in TeST sub- committee. 3.3.1 Issues of DELHI

Representative of DTL raised the following issues i) STLF was not working. Issue had been repeatedly raised with Siemens but no

action had been taken. i) Multisite link between DTL and RRVPNL was frequently down. Some kind of

application should be made available for direct monitoring in SCADA

ii) Repeated problem in Replay was observed.

iii) Problem in Schedule updation in SCADA was occurring frequently

iv) Process of Display Synchronization in bulk to be provided by Siemens.

v) Status of integration of UPS and DG data with SCADA system.- FRTU / Rainfall sensor integration

vi) Daily Peak Load Display in SCADA was not working whereas option was available in Graphic editor of IMM

vii) While synchronizing domain data, error occurs in ICCP

viii) EMS was not working

ix) Consequent to changes in Database during the synchronization process, changes were also required to be carried out in ICCP, causing delays.

Representative of POWERGRID informed that all major issues had been resolved and minor pending issues would be discussed with DTL and Siemens for necessary action.

3.3.2 Issues of H.P. Representative of HPSEB raised the following issues

i) Daily reports were being generated in MS- Excel using eDNA but the same could

not be displayed in the web. Therefore, provisions to link the eDNA reports, graphs, trends etc. with web server should be there so that one is able to view the daily reports online.

ii) There was no provision for displaying protection signal alarms (such as UFR, df/dt alarms) in world-maps using graphic editor of Information Model Management (IMM); to view the alarms, a template should be designed by M/s Siemens so that one is able to view the relevant alarms.

iii) Newly recruited Engineers were deployed at SLDC by M/s SIEMENS without practical experience of SCADA/EMS and hence they were not able to contribute in resolving the issues. Sufficiently experienced engineers should be posted by Siemens at SLDC.

iv) Information Model Management (IMM), a tool for additions/modifications in the database fails to transfer jobs mostly when additions/modifications are done in graphic editor and it constraints day to day activities.

v) As per CERC mandate, ADMS was required to be implemented by HPSEBL for which necessary provisions for operating Circuit Breaker remotely are required at SIEMENs RTU end.

POWERGRID informed that all major issues had been resolved and minor pending issues would be discussed with HPSEB and Siemens for necessary action.

3.3.3 Issues of HVPNL Representative of HVPNL raised the following issues

i) Uploading of Offline Reports :- HERC has directed to upload offline reports regarding power supply position,

voltage profile, frequency profile etc. on SLDC Website. M/s. Siemens should be asked to provide the Tab button in web site to link to the off line report at the earliest possible.

ii) Installation of SSL Certificate- The website Haryana SLDC (www.haryanasldc.org) was not opening on different

browsers. Hence during meeting on 28 & 29.01.16, it was decided that each

constituents has to procure the SSL Certificate to resolve the issue. The SSL certificate was procured but it could not be installed in spite of efforts by M/s Siemens Engineer.

POWERGRID agreed to take up above issues with SIEMENS.

Complete Due to non- availability of maintenance manual on system logs, it was not possible to

analyze above problem at UPPTCL end. 20. On 06.06.16 & 07.06.16 LAN A/OSI disturb/ready alarms appeared frequently. The

problem was reported to Siemens on 07.06.16 for analyzing and submitting analysis report but the same had not been submitted by Siemens.

21. Problem of SAN system not working at backup SLDC was reported on 11.05.16 but

it was still unattended. 22. Configuration overview display was showing status of servers only whereas as per

FDS for user Interface (page3/of 148) it should give an overview of current server status and peripheral device statuses and current connections to the LANs and the assignment of the printers. M/S Siemens were requested to prepare the display accordingly but the same had not been done nor any write up had been given so that overview display may be modified by UPPTCL.

23. Polling to all terminal servers (Lko as well as at sub LDC) stopped on 15.07.2016

13:20:Hrs. Reason for this happening was unknown. POWERGRID informed that all major issues had been resolved and minor pending issues would be discussed with UPPTCL and Siemens for necessary action.

3.3.5 BBMB issues

Representative of BBMB raised the following issues i) Database Syncronisation:

Representative of BBMB stated that based on the discussions held in the 7th

meeting of TeST sub-commmittee, a document containing database synchronization procedure was forwarded by POWERGRID vide their e-mail dated 02.06.2016. The document was perused and it was found that the procedure did not provide methodology for synchronization of TNA, IFS and ICCP databases. In this regard, the clarification was sought from POWERGRID vide email dated 05.06.2016. However, M/s SIEMENS had neither provided clarifications nor incorporated necessary modifications in the document. He further stated that they were facing lot of problems in maintaining the availability of requisite real time data at BBMB SLDC in the absence of proper database synchronization procedure. POWERGRID informed that the issues raised by BBMB had been forwarded to M/s SIEMENS and would be sorted out within a fortnight.

ii) Site Acceptance Test of EMS Functions: Representative of BBMB informed that M/s Siemens engineer was to visit BBMB SLDC for clarification/closure of EMS SAT pending points at site as per the meeting held at POWERGRID on 28.01.2016. In this regard, an engineer from M/s Siemens visited BBMB SLDC to resolve the pending EMS SAT issues. Nine (9) variances pointed out by BBMB during EMS SAT were not resolved by M/s SIEMENS. POWERGIRD intimated that they have referred the pending SAT variances to their LD&C department and would revert back to BBMB once the inputs are received from them. iii) RTU Time Synchronization Failure: Representative of BBMB stated that in the meeting held at POWERGRID on 28.01.2016, it was informed by BBMB that the new RTUs supplied by M/s SIEMENS under ULDC Phase – II were not getting time sync from GPS properly, however the issue was unresolved. It was decided that the issue would be taken up with M/s SIEMENS jointly by BBMB & POWERGRID in the joint meeting to be held at BBMB SLDC. iv) Some Alarms from SIEMENS RTUs getting reported after considerable

delay: Representative of BBMB stated that some of the alarms generated by SIEMENS RTUs were getting reported at BBMB SLDC after considerable delay. The problem had been observed at all SIEMENS RTUs installed at various BBMB locations. In this regard, a copy of the Alarm Summary log was also forwarded to POWERGRID & SIEMENS. However the issue remained unresolved. POWERGRID informed that the matter had already been taken up with M/s SIEMENS and would be discussed again in the joint meeting to be held at BBMB SLDC. v) Availability and Maintenance of VCS System: Representative of BBMB informed that they had requested POWERGRID to provide the guidelines for regular testing and maintenance of VCS system in the

meeting held on 28.01.2016 at POWERGRID, however the same was not supplied. BBMB further informed that M/s SIEMENS had not awarded the AMC of VCS System to its OEM and requested POWERGRID to advise M/s SIEMENS to do so at the earliest. POWERGRID agreed to supply a copy of testing and maintenance procedure of VCS to BBMB within a week. Further, it was decided that POWERGRID would persuade M/s SIEMENS to award the AMC of VCS System at the earliest. However, in case M/s SIEMENS fail to award the AMC of VCS System within a reasonable time, POWERGRID may award the AMC of VCS System to its OEM directly on the risk and cost of M/s SIEMENS. vi) Furnishing of As-Built Drawings: Representative of BBMB informed that the quality of as-built drawings submitted by M/s SIEMENS was very poor and the drawings did not contain requisite details. It was decided that the issue would be taken up with M/s SIEMENS jointly by BBMB & POWERGRID in the joint meeting to be held at BBMB SLDC. vii) Running of State Estimator Representative of BBMB stated that they were facing lot of problem in keeping the State Estimator running due to Database Synchronization issues. BBMB stated that they have 100% telemetry of all its stations and all the circuit breakers and isolators were wired and reporting, however on account of power system changes in other constituents, the SCADA & EMS model was updated by respective constituent in their own database but the same was not propagated to other constituents. After detailed deliberations, it was decided that NRLDC would share its TNA model on monthly basis with all constituents during database synchronization process so that the changes made by all constituents in TNA are updated at all SLDCs 3.3.6 Issues of Punjab Representative of PSTCL raised the following issues: i) SAT Observations (SCADA):-Some of the Observations as pointed out by Punjab SLDC during SAT (SCADA/EMS) under ULDC Ph-II were pending. ii) Problems in Custom Log Tool: The issue regarding proper functioning of Custom Log Tool was being taken up with M/s Siemens Ltd. since long time. M/s Siemens Ltd. tried to solve the issue in the past, but still errors in the Custom Log tool vis-à-vis EDNA had been observed for the month of June. Detailed report in regards to previous 6 Months was attached (Annexure-II to the agenda). As % availability report was being sent to CERC on monthly basis, therefore the report generated through custom log needed to be corrected in all respects, so that time & efforts put in by

PSTCL for manually can be minimized. POWERGRID was requested to take up the issue with M/s Siemens Ltd. In this regards. iii) Integration of SCADA system with ArcGIS 10 was pending from M/s Siemens Ltd. iv) Integration with ABT Based Scheduling Software & Open Access with SCADA system was pending v) Supply/Current Status of Splitters(56 No.) and Terminal Servers(16 No. 16 Port Terminal Servers and 6 No. 24 Port LAN switches for Terminal Servers) may please be informed to PSTCL vi) 1 No. Weather Sensor had been supplied by M/s Siemens, but installation/commissioning was pending. Status in this regard was sought. vii) Edna web had not been integrated in web server of PSTCL provided by M/s Siemens under ULDC Ph-II. POWERGRID was requested to update the current status. viii) It was brought to the notice of all concerned that domain name for Siemens web Server had been registered as https://punjabscada.org/CorporateUI by Punjab SLDC. Also necessary SSL Certificate had been bought & incorporated by PSTCL for the web server provided by M/s Siemens under ULDC Ph-II. It had been observed that some user had reset the password of the web server of PSTCL as password change option was present on logon screen, resulting into login issue. Other users were only able to log in the system, only after the password was reset by M/s Siemens, as advised by PSTCL. In order to avoid such incidents in the future, M/s Siemens had been requested by PSTCL to disable the password reset Link at the user level, with the facility of change of password only being available to administrator i.e. SLDC Punjab.

ix) After The SAT of Multisite functionality was conducted by M/s SIEMENS at PSTCL SLDC, PSTCL & BBMB faced data interruption at both ends. The data was restored by PSTCL after disconnecting the multisite link. Multisite link was not functional at the time of the meeting, however, data was being transferred through ICCP. As already informed vide E-mail 18-05-16, M/s Siemens was requested to look into the issue.

x) Regarding problem in VCS System: Due to problems in VCS system in the past, various meetings to be held via VCS system were impacted, for which matter was taken up with POWERGRID. The problem got resolved on 18th

July 2016. POWERGRID was requested to ensure availability of VCS system. POWERGRID informed that VCS link had been shifted to Tejas network.

POWERGRID informed that all major issues raised by PSTCL had been resolved and minor pending issues would be discussed with PSTCL and Siemens for necessary action.

3.4 RTU related Issues

3.4.1 Configuration of df/dt & UFR relays with RTUs.

Representative of HPSEB informed that SIEMENS vide e-mail dated 17.06.2016 had intimated that configuration of df/dt& UFR relays with RTUs was not in the scope of M/s SIEMENs and only SCADA end configuration would be done by SIEMENs. He requested advice to M/s SIEMENs for configuration of df/dt& UFR relays with RTUs.

Representative of POWERGRID agreed to take up the issues with SIEMENS.

3.4.2 Preventive maintenance of RTUs.

Representative of HPSEB informed that the preventive maintenance had been completed by SIEMENS, but the following issues related to RTUs had not been resolved:

I. Interfacing of bays at 220kV S/Stn, Hamirpur-II:- a) 220/132 kV Transformer-3 HV side (Analog/Digital) b) 220/132 kV Transformer-3 LV side (Analog/Digital) II. Interfacing of bays at 220kV S/Stn, Baddi:- a) 66 kV Baddi-Akanwali-2 feeder (Analog/Digital) b) 66 kV Capacitor Bank (Digital) c) 33 kV Capacitor Bank (Digital) d) 11 kV feeders (No. 24 to 30) - 7 Nos. (Analog/Digital) e) 11 kV Capacitor Bank (Digital) Representative of POWERGRID agreed to take up the issues with SIEMENS.

3.4.3 Others issues related to RTUs

Representative of HPSEB informed the following issues related to RTUs needed to be resolved: a) Interfacing of existing Temperature & Humidity Transducer with existing

SIEMENs RTU at 220kV Sub-Station Baddi. b) Log sheet generation from LDMS at 7 Nos. locations where SIEMENS RTUs

have been installed. c) Conducting an on-site training program at Hamirpur Sub-LDC on LDMS for

editing/interfacing bays/signals. d) Mismatch of the analog values & incorrect digital status at certain locations as

received in the SCADA System with respect to the field values and rectification thereof.

e) Interfacing of OLTC transducers installed at 7 Nos. RTU locations by M/s SIEMENS with SIEMENS RTU/LDMS/SLDC system. Representative of POWERGRID agreed to take up the issues with SIEMENS.

3.4.4 Providing Redundant Communication Channel for RTUs installed at ISTS points Representative of HVPNL stated that POWERGRID was not attending the

suspected RTUs in timely manner e.g the data of 400 KV Kaithal ICTs was suspect on 24.06.2016. In spite of repeated requests to POWERGRID and NRLDC, the data was restored after 7 days i.e. on 01.07.2016. He opined that it was evident that POWERGRID was not reviving the suspected RTUs data, which caused the incorrect display of drawl of Haryana from ISTS points. Moreover NRLDC had not substituted the values during the period. To avoid the frequent failure of RTU data, he requested POWERGRID to provide the redundant channel for data communication of RTUs up to NRLDC/SLDC, which are taken in ISTS drawl of Haryana. This would avoid the frequent outage of these RTU data. Representatives of POWERGRID and NRLDC agreed to take necessary action for timely substitution of suspected data from RTUs controlled by CTU.

3.5 Cyber Security

3.5.1 Compliance to requirement of Cyber security audit Representative of DTL stated that Cyber Security Audit was not done by SIEMENS in DTL area. POWERGRID agreed to take up this issue with M/s SIEMENS.

4.1.0 Present Status of Telemetry 4.1.1 Non-Availability / Reliability of Telemetry

Representative of NRLDC stated that they had started sending the daily availability of telemetry and the same was also uploaded to NRLDC website on weekly basis as discussed in the previous TeST sub-Committee meetings. He requested constituents to verify the availability report thus prepared by NRLDC. However, except UPPTCL, there was no comment from any Utilities and the same was assumed to be correct. Thereafter, the status of availability was discussed constituent wise for further improvement.

Representative of NRLDC stated that the SCADA system of PTCUL was integrated on single link and it had been observed that the reliability the link was very

4. Telemetry Related Issues

poor which was leading to non-availability of PTCUL data at NRLDC. It was desired that redundant link may be provided for data reliability. In 7th

The sub-committee desired to know progress in the matter. However, no representative of PTCUL attended this meeting.

TeST sub-committee meeting dated 11.01.2016, it was informed by representative of PTCUL that they had taken up the work of wideband connectivity from Dehradun to Rishikesh, which was expected to be completed by July’16 and redundant link would be configured on that wideband path.

4.1.2 Telemetry of digital status

Representative of NRLDC recalled that the importance of correct Digital telemetry in day to day system operation had been discussed earlier and also the requirement of correct digital telemetry for running the State Estimator was also deliberated. NRLDC presented the availability of digital status data from different Constituents based on the snap shot taken on 16:00 hrs of 25.07.2016, which was as follows :

Utility No. of CBs CBs Not Available %age Avail

Central Sector 2780 579 79% BBMB 554 73 87% DTL 475 52 89%

RRVPNL 2202 1024 53% PSTCL 1054 210 80% UPPTCL 2547 1258 51% HVPNL 937 123 87%

NRLDC informed that there were major inconsistencies in digital data in the following station which needed immediate attention : Central Sector: Agra 400, Auraiya, Ballabhgarh, Dadri-Th, Jalandhar, Kishenpur,

Mainpuri, Meerut 400, Rihand NT DTL : Bamnauli, CCGTB BBMB : Dehar RRVPNL : Barmer 400, Bhilwara 400, Merta 400, Bikaner 400, Deedwana,

Heerapura 400, Jodhpur 400, Suratgarh-TPS UPPTCL : Agra-1, Anparat-T, CB Ganj-1, Gorakhpur-1, Lucknow-1, Moradabad-

1, Muradnagar-1, Obra-B, Sultanpur-1, Unnao All the Constituents were requested to look into the telemetry of the digital status at least for 220 kV and above stations so as to improve the visibility of the network and to facilitate better network analysis through State Estimator.

4.1.3 Calculation of actual drawal in SCADA Representative of NRLDC informed that the drawal calculated in SCADA and Interface Meters are checked on weekly basis at NRLDC and abrupt major deviation were observed due to the following reasons :

i. Non-reliable telemetry – Sustained failure of telemetry ii. ICCP failure iii. Addition of new lines / element or LILO of lines in the network

He stated that the reliability of the communication system must be improved so that failure of ICCP links and RTU/SAS telemetry is addressed. It was observed that telemetry was not restored for prolonged duration which was leading to serious problem in day to day despatching. He added that though the database coordinators were taking all precautions to modify the drawal calculation to take care the network changes, some changes might go unnoticed at lower voltage level which may create major deviation. He requested member to ensure availability of communication and maintenance of telemetry. He was of the opinion that a reporting process could be framed for quick restoration. He recalled that the error checking for the tie lines were also discussed during earlier meetings and it was decided to compare the SEM and SCADA data for each point. The points for which %age errors are more than 3% were to be reported for correction. It was observed that except UP & HVPNL, no report was available for discrepancy and hence it was presumed that there was no error found at least in the tie lines on which drawal calculations are being done. The drawl comparison between SEM and SCADA was shared with the members present for the drawal of all the Constituents. It was mentioned that the difference was mainly due to outage of telemetry which needed to be improved and made reliable to facilitate day to day system operation. NRLDC also mentioned that it was decided that all the Constituents would analyze the drawal data link wise and report to the concern Utility for correction. NRLDC informed that the details were only available from UP and the same had been rectified except two lines for which action had been initiated with POWERGRID.

All the members agreed that there was no problem in monitoring the drawal data in real time.

4.2 Telemetry issues

Representative of UPPTCL informed following telemetry issues.

4.2.1. Mismatch between Interface meters & SCADA data:

i) Though Block wise comparison of data mismatch had been reported regularly since March’16 inaccuracy in SCADA data for following calcheck elements maintained by POWERGRID still persisted. SR NO.

Apart from the matter being communicated to NRLDC /POWERGRID regularly, this issue was raised on several occasions including previous meetings of Test Sub Committee, but the problem was not resolved. He stated that in view of the commercial importance of the data, the issue may be taken up in right earnest. ii). In case of calcheck lines, generally Telemetry data from UPPTCL substation was used for calculations. However in case of failure of this data, there was provision in system to substitute Remote /other end data, utilizing ‘Redundant data Sources ‘ option in SCADA to maintain reliability /accuracy in state drawl figures. An alternate set of Lines /Transformer data also summarizing State drawl figures was continuously monitored by SLDC to crosscheck calcheck figures for efficient system operation. Therefore data reliability & continuous availability of these alternative elements along with remote end data of interstate lines (which are part of calcheck) should also be ensured on priority. He requested that data inconsistencies observed on such elements should be addressed at the earliest.

POWERGRID agreed to analysis the data and revert back to UPPTCL with necessary action.

4.2.2. Provision of dual data routes for calcheck RTUs

Representative of UPPTCL stated that the issue of provision of dual data routes for calcheck RTUs was raised by UPPTCL in 7th

4.2.3 Issue of non-availability / intermittent availability of real time data from central sector

TeST sub-committee meeting and representative of POWERGRID had agreed to take necessary action. He requested POWERGRID to update about progress since last TeST sub-committee meeting. POWERGRID informed that this issue had been discussed under item 2.2.3 A.

Representative of UPPTCL informed that issue of non-availability /intermittent availability of real time data from central sector generation stations /sub-stations in UP was raised by them in the 7th

TeST sub-committee meeting, but availability of real time data for following Generating-station /transmission sub-stations was not satisfactory from Allahabad –PG , Auraiyya-NT, Bareilly –PG, Dhauliganga –NH, Kanpur –PG , Lucknow –PG , Narora-NP, Shahjahanpur –PG , Mainpuri-PG , Sitaraganj-PG, Tankpur –NH, Unchahar-NI, Varansi-PG.

POWERGRID informed that most of the RTU related issues in central Sector in UP had been resolved and agreed to rectify problem at remaining stations at the earliest.

4.3. HVPNL telemetry issues

Representative of HVPNL informed the following telemetry issues.

4.3.1 Non-restoration of Suspected RTU data of ISTS Drawl Points of Haryana

Due to frequent suspected RTU data of ISTS Drawl Points of Haryana, significant difference occurs in UI data from SCADA & Interface Meters of Haryana. Some time, it takes 2-3 days in restoration of data. Therefore, he requested POWERGRID to restore the suspected RTU data on priority basis. Representative of POWERGRID agreed to look into issues pointed out by HVPNL. SE(O) NRPC requested Haryana SLDC to follow NRPC approved Procedure to verify the drawal data on weekly basis and to find out reasons for discrepancy, if any ( Item B.25 of Minutes of meeting of 32nd TCC/36th NRPC held on 23rd and 24th

4.3.2 Nomination of Nodal Officer of POWERGRID for telemetry related issues

December 2015) to check the drawal data on weekly basis to ensure continuous validation of SCADA data in real time.

Representative of HVPNL stated that telemetry related issues were taken up with DGM/NRLDC by XEN/SCADA, HVPNL, Panipat regularly for restoration of suspected data of POWERGRID stations. However, it was advised by NRLDC to take up the matter directly with POWERGRID.

POWERGRID has two sub-region namely NR-1 & NR 2 in Northern Region, hence it would be difficult to take up the matter with the individual officers. Hence it was requested to nominate a nodal officer of POWEERGRID for taking up the matter for revival of data.

POWERGRID informed that Sh. Y K Dixit, AGM (ULDC) POWERGRID will continue to communicate and coordinate the TeST sub-committee related issues of other two sub- regions (NR-II and NR-III) of Northern Region.

4.3.3 Substitution of Suspected data as per field values Representative of HVPNL stated that the data of ISTS points get suspected many times during odd hours also. If MW values of these ISTS points are not replaced with actual one, then due to freeze value, it depicts the wrong drawl of Haryana from grid. It causes the huge mismatch in UI data of SEM & SCADA of Haryana. However it should be got replaced by SCE, NRLDC till the RTU data is revived.

But the Shift Operators / Shift Charge Engineers at NRLDC do not replace the suspected data as per actual field values. Due to this Haryana drawl is affected & due to extra charges occurs on UI / Over Drawl (OD) more than 150 MW from grid as per provision of Unscheduled Interchange (UI) Regulations 2014. He, therefore, requested that the SCE, NRLDC may be adviced to replace the suspected MW values of ISTS points.

After deliberations, it was agreed that SLDC and NRLDC shall replace suspect data of state and central sectors respectively. SLDCs shall ensure 100% availability of telemetry for proper analysis of suspect data of SCADA vs Interface meter data.

5.1 Status of the installation of URTDSM system

Representative of NRLDC informed that the installation work of the PMU had started and the same was being integrated with the PDS system provided at NRLDC/SLDCs. Since the historian had not been made available, the data being received cannot be utilized for the system analysis purpose. It was desired that the data should be available, for system analysis and requested POWERGRID to furnish the status of the installation of the historian under this project .

Representative of POWERGRID informed that PMUs at 74 substation had been supplied and installation had been completed at 70 nos of stations out of total 114 nos WAMS of sub-stations covered under URTDSM Project (Phase-I) in Northern Region. Data of 30 nos of sub-stations had been reporting at NRLDC over PDS. FAT for Phasor Data Concentrator (PDC) for Package-II was going on at Alstom works in Noida. But FAT for PDC for Northern Region was scheduled in Oct’ 2016.

5.2 . Status of the installation of URTDSM system

Representative of BBMB informed that the URTDSM Project was scheduled to be completed by January, 2017 as intimated by POWERGRID in 6th
