Wind-power-station power output counterbalance system and working method thereof

The invention relates to a wind-power-station power output counterbalance system which comprises a wind speed acquisition and conversion circuit, an actual wind-power-station analog module, a differential amplifying circuit, a comparison circuit, a control circuit, a current transformer and a superconducting magnetic energy storage device, wherein the superconducting magnetic energy storage device comprises a chopper, a wave filter and a feedback circuit. The working method of the wind-power-station power output counterbalance system comprises the following steps: (1) converting a wind signal into an electric signal; (2) producing a signal which has the same output variation law as the actual wind power station; (3) processing by the differential amplifying circuit; (4) performing the circuit comparison with the power signal output by the superconducting energy storage device; (5) and controlling the conduction of a triode in the current transformer, and outputting power of the multiple superconducting energy storage devices. The invention has the advantage of storing the electric energy by utilizing the superconducting magnet, thereby greatly enhancing the energy storage density, reducing the energy consumption and realizing the synchronous inhibition on the power output fluctuation of the wind power station.
