The synchronous closing mode is analyzed,and its detailed conditions and implementation scheme are given. With the cylic frequency measuring,the hardware platform of line protection,measuring control device,with CPU STM32F407 as its core,is used to develop the synchronous closing software and realize the function. The results of test and dynamic simulative experiment for microcomputer-based relay protection system show that,the proposed implementation scheme is reasonable,which can quickly and accurately realize the synchronous closing function to enhance the performance of feeder protection.
