    relays is regularly being done by WRPC Secretariat and the record of the same

    is maintained as per provision in IEGC.

    He further informed that during last NPC meeting, it was decided that the

    issue of change in AULFS states and quantum of load shedding associated with

    these stages need to be discussed in all RPCs. Accordingly, a special meeting

    was convened to review AUFLS stages of frequency & quantum of load

    shedding on 13.03.2018 at WRPC Mumbai. After detailed discussion,

    consensus was made among all participants on followings:

  • Minutes of 505th OCC meeting held on 21st March, 2018 Page 33

    13 STATCOMs had been approved in the CEA Standing Committee

    for providing dynamic reactive compensation.

    STATCOM comprised of dynamic reactive compensation as well as

    the static compensation from the mechanically switched reactors

    and capacitors. The maximum and minimum composite

    compensation would be as under:

    Gwalior 450 MVAr 325 MVAr

    The reference voltage of the STATCOM could be varied to observethe composite steady state response of STATCOM along withMechanically Switched Reactors/Capacitors. The transientresponse of STATCOM during trial operation would be visible onlythere is a perturbation in the grid during that period near thelocation where STATCOM is installed.

    As per the document received from POWERGRID the STATCOMcould operate in constant reactive power control mode and voltagecontrol mode.

    As per IEGC, the duration of trial operation is 72 hours forgenerating units and 24 hours for transmission lines, reactors andICTs. CIGRE Technical Brochure 663 provides guidelines for testingand trial operation of STATCOMs.

    With reference to the trial operation there were divergent views.
