摘　　要：分析一起事故导致发电机有功功率突降异常的危害,提出应用零功率保护的解决方案。介绍零功率保护原理,利用保护原理结合事故分析,论证发电机应用零功率保护的必要性。结合反事故措施,探讨零功率保护和热工保护的关系,进一步论证发电机应用零功率保护的必要性。The damage of abnormal generator active power sags caused by an accident is analyzed. The solution scheme that applies the zero power protection is proposed. The principle of the zero power protection is introduced. The necessity of the zero power protection applied in generator is demonstrated by the protection principle and accident analysis. The relation between zero power protection and thermal protection are discussed combining with anti-accident measures, which further demonstrates the necessity of the zero power protection applied in generator.
