Transformation Design for Generator Circuit Breaker Added to 4~# Unit of Wanjiazhai Hydropower Station

论述了万家寨水电站4~#机增设发电机断路器改造设计,解决了多年来山西电网侧中性点运行不灵活,机组低负荷运行时水利用效率较低的问题,并有效缓解了调峰运行时高压断路器操作过于频繁的问题,消除了安全隐患,提高了电站在系统中的安全运行水平。

This text discusses the transformation design for generator circuit breaker added to 4~# unit of Wanjiazhai Hydropower Station,it solves the problems of inflexibility in operation of neutral point at power grid side in Shanxi for many years,and low efficiency of water utility in low load operation of unit,effectively alleviates the excessive frequency of high voltage circuit breaker in peak load operation,eliminates the security risks,and improves the safety operation level of power station.
