采用单片机与PLC对电力系统继电保护的改进方法

Improvement Solution of Relay Protection for Electric System by Adopting Single-chip Microcomputer (SCM) and PLC

对我国电力系统继电保护所存在的一些固有缺陷进行了论述,针对该缺陷从理论上提出了改 进方案,并论述如何利用单片机及PLC技术进行方案实施,达到了预期效果。

The paper discusses some inherent defects on relay protection for electric system in China and puts forwad an improvement solution theorectcially. It also introduces how to put the soultion in practice by adopting SCM ansd PLC technolody, which achieves desired result.
