摘要：On the basis of the mathematical model of doubly-fed variable speed pumped storage unit, the paper proposes a coordinated control strategy between the AC excitation system and governor. Based on the operation curve of pump-turbine, the optimal speed and gate opening of doubly-fed variable speed pumped storage unit are determined by active power command and real time water head. Simultaneously, the method taking into account of active power command and frequency fluctuation will make doubly-fed variable speed pumped storage unit to automatic regulate the frequency rapidly. Finally, the doubly-fed variable speed pumped storage unit is simulated by Real Time Digital Simulator (RTDS) software under the generating and pumping mode to validate and analyse the operational characteristics and performance.
