摘要： In first aspect, a method of operating a wind turbine farm is provided. The wind farm comprises a plurality of wind turbines, a respective circuit breaker, a synchronous condenser and a synchronous condenser circuit breaker. The synchronous condenser and the plurality of wind turbines are connected to the common connection point by closing the synchronous condenser circuit breaker and respective wind turbine circuit breakers, respectively. The grid voltage is measured at the common connection point and the measured voltage compared with a predetermined normal operation voltage range. If the measured grid voltage is out of the predetermined normal operation voltage range, the plurality of wind turbines are disconnected from the common connection point by opening each wind turbine circuit breaker. The synchronous condenser is maintained connected to the common connection point by keeping the synchronous condenser circuit breaker closed. A wind farm and a computer program are also provided.

摘要： The present disclosure provides a power supply system method for an AC load (10). The system includes a power supply device (11, 21, 31A, 31B, 41) and a DC/AC converter (12, 22, 32, 42). An AC side of the DC/AC converter is coupled to an AC grid (9) and the AC load through an AC bus (8). The power supply device outputs DC electric energy and is coupled to a DC side of the DC/AC converter through a DC bus (13, 23, 33, 43). The power supply device includes an energy storage circuit (111, 211, 311, 411) and a controller (112, 212, 312, 412). The energy storage circuit includes a first energy storage circuitry (1111, 2111, 3111, 4111) and a second energy storage circuitry (1112, 2112, 3112, 4112). The controller is configured to control a conversion operation of the first energy storage circuitry to output a low-frequency power to the DC bus, and a conversion operation of the second energy storage circuitry to output a high-frequency power to the DC bus.
