| Abstract: |
| 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. |
