摘　　要：近年来,在发电机同期控制系统设计中存在取消自动准同期合闸回路中同期检测闭锁的情况;其理由是同期控制装置已微机化并"设计严密",由于取消同期检测闭锁"有利于使发电机的并网过程不致因允许频差过小产生频差符号交替变换而延缓并网过程"。对发电机同期控制系统中的同期检测闭锁必要性进行了分析,提出了在发电机同期控制系统设计中不能取消同期检测闭锁功能的观点。In recent years,when designing generator synchronous control system,‘synchronous block function＇ has been canceled in the synchronous closing circuit. The reason is ：synchronizer has been designed with microcomputer and design is rigorous. Because to cancel synchronous block function,when a generator synchronizes to power grid, the procedure will become more fast. This paper analysed the necessity of the synchronous block function,and emphasized the synchronous block function can not be canceled.
