摘　　要：目前抽水蓄能电站在电网安全稳定运行中发挥着日益重要的作用,大型抽水蓄能电站机组抽水工况启动可以采用背靠背方式。由于硬回路设计上的缺陷,拖动过程中存在拖动机组与被拖动机组灭磁开关分闸不同步的现象,对发电机和启动回路造成巨大危害。针对这一问题,本文设计了可以实现灭磁开关同步分闸的硬回路。At present,pumped storage power stations play an increasingly important role in the safe and stable operation of the power grid.Large-scale pumped storage power stations can be switched on in back-to-back mode.Due to the defects in the design of the hard circuit,there is a phenomenon that the demagnetization switch of the drag unit is out of sync with the demagnetization switch of the unit being dragged,which does great harm to the generator and the starting circuit.In order to solve this problem,a hard circuit which can realize synchronous opening of demagnetizing switch is designed in this paper.
