14.5. Chairperson, NPC/CEA was of the view that RPCs are not directly assigned for monitoring
of PSDF projects and suggested that monitoring of PSDF sanctioned projects may be done
through the Project Monitoring Group of PSDF which has been created for the same. All
RPCs endorsed the view of Chairperson, CEA.
14.6. MS NPC was of the view that the Project Monitoring Group of PSDF conducts various
meetings at regional levels for monitoring the implementation of sanctioned scheme and
these meetings were impactful in terms of reduction in delay in completion of projects and
also improves the disbursement of fund to project entities. The purpose of bringing this
agenda in NPC meetings was to sensitise the states for timely completion of projects through
RPCs
14.7. Chairperson, NPC/CEA raised concern on delay in sanctioning of the projects under PSDF.
On this MS, NRPC suggested for a dedicated online portal for PSDF for uploading of DPR,
comments of TESG, and inputs of project entities so that the project may be sanctioned in
limited time period.
14.8. ED, NLDC informed the committee that the portal was already developed one year back but
it has not been utilised by the entities. NLDC stated that they would again request
the utilities /states to utilise the portal.
14.9. Chairperson, NPC/CEA advised NLDC that the portal to be revived and to be made fully
operational. NLDC shall also informed states/utilities regarding the portal and suggest them
to utilise it for early sanctioning of projects in limited time period.
Decisions in the meeting:
14.10. NLDC shall revived the portal again and made it functional completely. POSOCO shall also
disseminate the information to states/utilities regarding the portal and suggest them to utilise
it for early sanctioning of projects through PSDF.
[Action-POSOCO/NLDC]
14.11. It was decided that the agenda item may be dropped as the monitoring of PSDF sanctioned
projects is done through Project Monitoring Group (PMG) of PSDF.
15. Membership of RPC forum (ERPC- Agenda)
15.1. Government of India has a vision of achieving Renewable Energy installation target of 150
GW and 450 GW by 2022 and 2030 respectively. The major challenge before the
government is the RE integration to the Indian Electricity Grid and smooth running of the
Grid in the Real Time operation. For resolving the issues of RE generators, smooth
integration and proper real time dispatch of RE generation, ERPC proposed a suitable
provision for inclusion of RE generators with threshold of 200 MW and above as a
membership of RPC forum.
15.2. In the 11th meeting of NPC, it was observed that the issue needs deliberation at the RPC
level first and afterward may be discussed at NPC level.
15.3. SRPC vide letter dated 05.07.2022(Annexure-VII) informed that the issue was discussed
in the 42nd meeting of SRPC. SRPC recommended that membership of two RE generators

with threshold of 1000 MW (and above) installed capacity in the region on rotational basis.
The participation of such generators would be limited to technical and operational issues.
Deliberations & decisions in the meeting
15.4. ERPC briefed the agenda to the Committee.
15.5. MS, NPC informed that SRPC had sent their recommendation to consider membership of
two RE generators with threshold of 1000 MW (and above) installed capacity in the region
on the rotational basis. The participation of such generator would be limited to technical and
operational issues.
15.6. Chairperson, CEA/NPC suggested that all RPCs may share their views to NPC Secretariat.
The views of all RPCs may be analysed and a holistic recommendation may be prepared by
NPC Secretariat for approval.
[Action-All RPCs and NPC Secretariat]
16. The meeting ended with Vote of thanks to the Chair.

Summary of the Report
Ø Initially a Pilot Project was implemented by POSOCO with 52 Phasor Measurement Units
(PMUs) installed all over the Country progressively from 2008 to 2010. Based on the
experience gained in Pilot Projects, a Feasibility Report was prepared for Nation-wide
development of WAMS namely Unified Real Time Dynamic State Measurement
(URTDSM) Project. A Detailed Project Report (DPR) was prepared in 2012 for
implementation of 1740 PMUs on Pan-India basis. The Project was agreed for
implementation in a Joint Meeting of all the five Regional Standing Committees on Power
System Planning held on 5th March 2012. Also, it was decided that the project of
installation of the PMUs will be taken up in two stages.
Ø CERC granted in principle approval for the project in Sept’2013 with 70% funding from
PSDF & 30% equity from POWERGRID. CERC granted in principle approval for the
implementation of URTDSM Phase-I and advised to take up Phase-2 after receiving
feedback on Phase-I performance from POSOCO. POWERGRID took up the
implementation of URTDSM Project in Jan’2014 and 1409 PMUs are installed in Phase-I
of the Project (the increase in quantity of PMUs was due to addition of new bays etc. at the
substations). Nodal PDC at strategic substations, Master PDC at all SLDCs, super PDC at
5 RLDCs, Main & backup PDC at NLDC have been installed and are fully functional.
PMUs are installed at only those 400 kV lines which had connectivity of the fibre optic
network.
Ø Data of these PMUs is being utilized by power system operators as an analytical tool for
better system operation in real time as well as for off-line analysis. Operators are also
utilizing various facilities provided under the project which includes the GUI application
supplied by GE and 6 analytics have been deployed by IIT-B.
Ø In the 10th
NPC Meeting held on 9th
April 2021 it was decided to form a sub-committee,
under the Chairmanship of Member Secretary, WRPC with representatives from POSOCO,
CTU, POWERGRID, all RPCs/NPC. The Sub-Committee was entrusted to recommend
uniform philosophy of PMU locations, new analytics and requirement of up gradation of
Control Centre under URTDSM project and submit its recommendations to the NPC.
Ø The sub-committee held 3 meetings. The first meeting was held on 10.12.2021 and the
second meeting was held on 31.05.2022. In both the meetings IIT Bombay gave
presentation on the analytics developed in URTDSM Phase-I, improvements in these
analytics and futuristic analytics that can be undertaken under URTDSM Phase-II.

Ø The EPG group presentation was arranged by PRDC in the second meeting held on
31.05.2022 and the EPG LLC, USA highlighted various application analytics which are
deployed by power Utilities worldwide and are being used.
Ø The third meeting of the sub-committee was held on 14.09.2022 to discuss the finalised
draft report of the sub-committee.
Ø PGCIL has expressed some reservations on the recommendations of the sub-committee.
The same are attached at Annexure – 9.
Ø Based on the above discussions, the report has been broadly divided into 6 Sections
• Section-1 briefly explains the background discussions that took place in various meeting
for implementation of the PMU/WAMS project on pan India basis and the progress and
hardware implementation of the Phase-I of the URTDSM project.
• Section-2 briefly explains the OEM online and offline applications and its use.
• Section-3 deals with the PMU placement criteria and status of Phase-I analytics.
• Section-4 outlays various issues regarding hardware, application & analytics faced in
the Phase-I of the URTDSM project and feedback of stakeholders.
• Section-5 describes in brief discussions took place on requirement of PMUs that took
place in regional levels, various new applications/analytics that can be taken up in
Phase-II of the project.
• Section-6, the recommendations of the sub-Group on improvement of Phase-I
applications/analytics/hardware optimisation required to be taken up Phase-II,
placement/requirement of PMUs in phase-II and new applications/analytics required to
be implemented in Phase-II of the URTDSM project.
