大型水电站机组溜负荷原因的探讨

摘要

Load rejection events occurred occasionally in large hydropower units with different causes .With analysis on several load rejection events occurred in Gezhouba hydropower station , possible electrical and mechanical causes of such accidents are discussed .Technical improvements then can be made to reduce the chance of such accidents .%机组溜负荷在大型水电站机组中偶有发生，原因也各不相同，结合近几年来葛洲坝电厂几次机组溜负荷的案例，从电气和机械两个方面分析机组溜负荷的具体原因，从而加以技术改进，减少机组溜负荷事故发生。
