Page 12 of 21

The error checking for the tie lines were also discussed during the last meetings. It was decided to compare the SEM and SCADA data for each points and points for which % age errors are more than 3% will be reported for correction. It is observed that except UP & HVPNL, no report was available for discrepancy and hence it is presumed that there was no error found at least in the tie lines on which drawal calculations are being done. Members may confirm.

3.1.2 Manual replacement of calcheck data at SLDC end (Agenda by UPPTCL)

3.1.2.1 It was agreed earlier that in case of failure of RTU/SAS/Communication system of central sector entities manual replacement of data in SCADA will be done by NRLDC but the same is not being ensured properly.

3.1.2.2 Manual replacement of calcheck data at SLDC end is also a challenge as many of the POWERGRID stations are unmanned and therefore obtaining adequate value for replacement is arduous & time consuming. To overcome such recurrent problems a mechanism needs to be developed for timely acknowledgment, quick response & speedy resolution to these issues.

Members may discuss.

3.1.3 Monitoring of UFR, DF/DT and SPS feeder in SCADA( Agenda by NRLDC):

3.1.3.1 In the 10th

Following issues in respect of SCADA/EMS System installed at BBMB SLDC under ULDC Phase – II are still pending:

3.4.1.1 Implementation of Multisite Configuration:

The implementation of Multisite Configuration between BBMB SLDC and PSTCL SLDC is still pending due to non-availability of communication links. In the 10th

Members may discuss.

TeST meeting , it was intimated that a group was constituted by NRPC vide letter No. NRPC/OPR/108/04/2016/5328-40 dated 10.06.2016 and the report of the group was awaited. It was also deliberated that due to transfer of some of the members of the group, the proceedings of the group was affected.SE, NRPC requested all the concerned utilities to send nomination of an alternate member in the group, latest by 31.03.2017, so that the group may be reconstituted and the task is completed. POWERGRID representative informed that communication would be provided as per recommendation of the group after submission of the report.

3.4.1.2 Database Synchronisation:

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

Page 14 of 21

was sought from SIEMENS/POWERGRID vide email dated 05.06.2016. However, M/s SIEMENS had neither provided clarifications nor incorporated necessary modifications in the document. In 8th

Members may discuss.

Test meeting, the difficulties being faced during database modification and synchronization process was deliberated and to overcome these problems some proposals were suggested, but none of them have been implemented so far. Lot of problems are being faced in maintaining the availability of real time data at BBMB SLDC in the absence of proper database synchronization procedure. The issue was discussed in detail in the 10th meeting of TeST and after detailed deliberations it emerged that there were several similar issue, which needs proper coordination with concerned vendors. It was decided that a meeting would be arranged at NRPC, New Delhi with all the concerned vendors of ULDC scheme and the concerned State utilities to discuss and resolve the issues.

3.4.1.3 Running of State Estimator:

BBMB is facing problems in keeping the State Estimator running due to Database Synchronization issues. It may be pertinent to mention here that BBMB has 100% telemetry of all its stations and all the circuit breakers and isolators are wired and reporting. However, on account of power system changes in other constituents, the TNA model is updated by respective constituent in their own database but the same is not propagated to other constituents. The matter was discussed in the 8th Meeting of TeST and 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. In the 10th

Meeting of TeST, BBMB expressed concern that unless a proper procedure is put in place for periodic synchronization of common TNA model and ICCP database, it would not be possible to run the State Estimator successfully. However, the proposal of BBMB was not accepted by NRLDC. After detailed deliberations, it was decided that training of one week duration would be arranged at each Constituent location. It was also decided that all the Constituents would nominate the officers who are responsible for running State Estimator, so that hands on training could be imparted to them directly on their system. It is requested that the training on TNA applications may be arranged at the earliest.

Page 15 of 21

In the 36th USMG Meeting held on 18.02.2014, it was brought out by BBMB that the ministry of Communication & Information Technology, Government of India has circulated the IPv6 Deployment Roadmap to all the Central Government Ministry/Department/State/UTs to facilitate them in the task. A copy of the roadmap is available on internet at http://www.dot.gov.in/sites/default/files/Roadmap%20Version-II%20English%20_1.pdf . All the Government Organizations were advised to follow a phased transition approach depending on the complexity and the IPv6 readiness of their current networks and systems. Accordingly, it was suggested that the SCADA/EMS System, which was under procurement at that time, may be got configured on IPv6. It was however intimated by POWERGRID that the installation & commissioning of SCADA/EMS System under ULDC Phase – 2 is at an advance stage. The system platform being procured is IPv6 ready but at present is being commissioned with IPv4 keeping in view the integration requirements with existing system. After commissioning of new system, the security audit of the system shall be got conducted and the recommendations of IPv6 Deployment Roadmap shall be progressively finalised and implemented within deadline set by ministry i.e, Dec., 2017. Since the commissioning of new SCADA/EMS System has been completed, POWERGRID may implement the roadmap for transition of SCADA/EMS IT System from IPv4 to IPv6, which is to be completed by Dec., 2017.

5.1 URTDSM Project Status (Agenda by POWERGRID)

Materials has been dispatched for 5 control centres under URTDSM Project and for balance control centres it will be dispatched by June month end. All the Constituents should ensure space for installation of Servers in SLDC control rooms and availability of manpower to implement the Project before target date, Dec, 2017.

5.2 Constraints for URTDSM project (Agenda by POWERGRID): 5.2.1 Shutdown required for CT/PT termination at various station under URTDSM

Project

POWERGRID is installing PMUs at various sub-stations of central and state sector. For commissioning of PMUs at site, CT/PT and DI termination is required for existing CR panels. CT/PT termination for most of the stations has been done in live line condition. However some of the stations specially generating units of NTPC and UPRVUNL are insisting for shutdown for CT/PT termination.

After discussion with NRLDC for shutdown, vendor has been deployed 4 times at Obra-BTPS and 3 times at Singrauli station, however at last moment shutdown could not be allowed citing grid related issues. Now vendor is very reluctant to visit again at site citing shutdown issues and commissioning also hampered due to this. In each sub-station 30-30 min. shutdown is needed for each of the feeder for CT/PT connections.

Members may discuss.

5.2.2 Space for installation of PDC under URTDSM Project at PTCUL(Agenda by

POWERGRID):

PTCUL is yet to provide space for installation of PDS / PDC at SLDC Dehradun. PDS Materials were dispatched to Dehradun in Feb’16, However, PTCUL officials did not take delivery of PDS materials even the matter was discussed during 7th

PTCUL may ensure space for PDC at site.

TeST meeting, now PDS is temporarily stored at Dehradun sub-station of POWERGRID and FAT for PDC is going on and PDC will be dispatched in July’ 2017.

5.3 Latest update on URTDSM: (Agenda by PSTCL)
