-
摘要: 在发电机组解列过程中出现程序逆功率保护未及时动作的异常情况，为了保证发电机组运行安全，通过对程序逆功率保护的动作过程、保护的整定原则和动作逻辑进行分析，找到了发生异常的原因，并提出了处理原则和预控措施。Abstract: During the disconnection of generator sets, the program reverse power protection might not act in time. To ensure the safe operation of generator sets, analyses are carried out on the action process of reverse power protection, the setting principle and the action logic of reverse power protection, based on which the causes of such an anomaly are found, and the processing principles and pre-control measures are proposed.
