Tests on Participation in Rated Primary Frequency Control With Upper Control Range of 410 MW Successfully Carried Out at the Combined-Cycle Gas Turbine of Shaturskaya GRES

Shaturskaya GRES Branch of Unipro PJSC successfully carried out certification tests of power unit No.7 against the requirements of Standard of System Operator SSO 59012820.27.100.004-2016 “Norms of Participation of Combined-Cycle Gas Turbines and Gas Turbine Units in Rated Primary Frequency Control (RPFC) and Automatic Secondary Frequency and Active-Power Flows Control”. The purpose is to change the upper limit of adjustment range of combined-cycle gas turbine (CCGT) participation in RPFC.

The tests were carried out in cooperation with the agency of voluntary certification of electricity generation facilities – the All-Russian Thermal Engineering Institute – within the frame of inspection control of power unit No.7 participating in RPFC for more than a year. 

Thanks to tests the upper control range of CCGT for the RPFC increased from 393.3 to 410 MW.

Successful tests allow to continue participation of power unit in rated primary frequency control and maintain the reliability of operation of electric energy system.
