摘　　要：大型汽轮发电机在出现全厂送出线路故障、功率突降的工况下跳闸,可以避免对热力系统的危害,但也会导致全厂停电事故的发生。文章描述了某电厂因冰雪灾害导致双回路出线同时故障停电,对电厂两台机组零功率切机保护动作造成全厂停电事故原因进行分析,并对全厂停电后机组处理原则进行探讨。The trip of large turbo-generator under the condition of transmission line fault or sudden power drop can avoid the harm to the thermal system,but it will also lead to the occurrence of power failure of the whole plant.This paper describes the double circuit outlet fault due to a snow and ice disaster,analyzes the power failure of the whole plant caused by the zero power cut protection action of two units of a power plant,and discusses the principle of unit treatment after power failure of the whole plant.
