Power Unit No. 2 of Berezovskaya GRES Branch of Unipro PJSC has started providing services for JSC SO UES since January 2018. The services are rendered to ensure the overall reliability of the Russian power system as related to Rated Primary Frequency Control (RPFC).
To ensure compliance with the requirements of System Operator for these services, Berezovskaya GRES updated the automatic control system of turbine unit No. 2 and the hard and soft suite of the turbine control system, as well as readjusted the automation system, as part of the last year repair campaign.
Power Unit No. 2 of Berezovskaya GRES passed all the required tests and received the Certificate of Compliance with the System Operator’s standard setting the requirements for power units participating in RPFC within the power system of the Russian Federation.
RPFC is used to guarantee high quality of the primary frequency control and, therefore, minimise its deviations in the event of power imbalance in any part of the power system.
Power Unit No. 1 of Berezovskaya GRES Branch gained the right to render these services in December 2015 and it was the first Russian pulverized coal power unit to take part in RPFC.
