Minutes for the meeting of PSS Tuning
A meeting was held on 03.01.2017 at WRPC, Mumbai on PSS tuning with Excitation
Engineers of various entities in WR to discuss the status of PSS covered in WR PSS Tuning
Project, Status of PSS for all other remaining Generators in WR and tuning of all the generating
units whose capacity is greater than 50MW as per IEGC. The list of participants is enclosed at
Annexure – I.
SE (Protection & Studies), WRPC welcomed Dr. A. M. Kulkarni from IIT-B and all
the participants of meeting and briefed the members about the PSS tuning. A brief video was
presented on the PSS tuning activity carried out in WR wherein PSS tuning of 23 units was
taken up for which IIT-B was consultant. WRPC having a successful background in many
aspects of PSS tuning further exercise can be taken up for tuning PSS in remaining
generating units. Thereafter agenda items were taken up for discussion.
Item No 1: Status of PSS covered in WR PSS Tuning Project
As decided by WREB/WRPC in 114th WREB meeting, field tuning of PSS on
generators was done by a group comprising IIT-B as consultant, BHEL and utility excitation
groups. In all 23 units PSS were tuned. The status of these projects as of now was discussed
and updated as follows.

Item No 2: Status of PSS for all other remaining Generators in WR:
It was proposed to taken up the exercise of PSS tuning in WR, for which following
information was sought from ISGS, State Generating Companies, IPP’s connected to CTU,
and IPP’s connected to State having generating unit capacity more than 50 MW.
Unit No, Rated Capacity, Type of Excitation System, whether PSS provided or not,
whether PSS tuned or not, and manufacturer of excitation system. The data furnish by the
entities is enclosed at Annexure-2.
Item No 3: Proposal for Tuning:
SE (Protection & Studies), WRPC informed that,
i. As per IEGC Generators have to tune PSS. CTU/RPC can check the settings.
ii. Tuning of PSS is recommended to enhance stability. WR can utilize the
earlier experience and take up PSS tuning activity once again. However as
compared to earlier phase, knowledge of frequency response and theoretical
aspects must be spread to generators so that they can also participate in the
exercise. Training is also necessary. Further since PSS tuning helps in
enhancing Grid stability expenditure can be taken under PSDF.
After discussion following was agreed;
1) All the State owned Generating Companies would prepare a DPR for getting
the PSS tuned by the OEM of their generating units. This DPR would be put
up to the appraisal Committee for funding through PSDF with the
recommendation of WRPC.
2) The private generating companies shall get the PSS tuned from the
manufacturer at their own cost.
3) A detailed guideline on the adoption of the PSS settings and testing the PSS
would be prepared by WRPC in consultation with IIT-B and the same may
be referred by the generating companies during adopting PSS settings.
4) A training program on the PSS tanning activity shall be organized by IIT-B
for all the stake holders. The fees of the training program shall be borne by
the individual organization.
5) Software for checking the performance of PSS, analytically, would be
Minutes for the meeting on PSS Tuning held on 03.01.2017 Page 3
developed by IIT-B after discussing the requirements with WRPC. The copies
of the software then could be shared with the generating companies.
6) Simulation software for exciter/PSS control system simulation shall be
developed by IIT-B, which shall be made available to all the generating
companies of WR for checking/simulating the frequency response of the PSS
tuned system, so that they can select the settings.
7) After carrying out the tuning of PSS, the parameters/constants set by the
generating companies shall be communicated to WRPC for its verification.
This would be verified by WRPC through the software developed by IIT-B at
5) above.
8) The cost of the software’s at 5 & 6 be funded through WRPC fund.
