9 6.4 : CONTROLLING HIGH VOLTAGE DURING OFF-PEAK HOURS :- Switchable Shunt Reactors are being taken in service during high voltage conditions. However in view of inadequate shunt reactive compensation, the generating units are advised to contribute in voltage regulation by operating their units in under-excited mode (absorb Reactive Power) within the capability curve. The MW, MVAR and Voltage of generating units was analyzed for the month of Feb 2017 with the help of SCADA data available at WRLDC. In 494th OCC meeting of WRPC, WRLDC has drawn attention regarding MVAR generation at Satpura Power Station when bus voltage was above nominal. The scatter plot of MW Vs MVAR of unit and Bus Voltage Vs Reactive Power Injection by the unit has been plotted. It has been observed that generating unit at Satpura Unit No. 10 & 11 was injecting reactive power into the grid even when the bus voltage was above nominal. Such operation is not desirable and it is requested that AVR setting and the GT taps may be reviewed / adjusted so as to enable the unit to contribute in voltage regulation within the capability curve. The directives in this regard may please be adhered to control the high voltage during off peak hours. [Action: MPPGCL/NHDC/IPPs] 6.5 : MONITORING OF SCHEMES FUNDED FROM PSDF :- it was decided in the 6th meeting of NPC held on 19th December 2016 at Bengaluru, that all the RPCs in the monthly OCC meetings may follow up with the utilities to expedite the completion of schemes by giving due priority.
