摘　　要：同期系统是火电厂电气二次部分的一个重要组成部分,在发电机与系统正常并列过程中起着极为重要的作用。若同期并列操作不当或误动作,就可能引起非同期并列的严重后果。为此设计了一种具有100%非同期闭锁功能的发变组同期并网控制系统,以避免类似事故发生。The synchronous system is an important part of the electrical secondary part of thermal power plant,which plays an extremely important role in the normal parallel process of generator and system.If the synchronous parallel operation is improper or misoperation,it may cause serious consequences of asynchronous parallel operation.In this paper,a synchronous grid connected control system with 100%asynchronous locking function is designed to effectively avoid similar accidents.
