综述微机继电保护的故障分析及处理

Summary Fault Analysis and Treatment of PC Relay Protection

随着继电保护技术高速发展，大量微机保护已陆续投入到电网运行中，给变电站二次回路带来了一次巨大的技术革新，也像给电网公司的经济效益给予了保障，而继电保护是电网安全运行的重要保证，故我们继电保护人员的工作任务也将迫在眉睫。本文作者分析了多年的工作经验及总结，介绍了它的特点及优势，而后，对继电保护故障分析及处理系统进行了全面论述。

With the rapid development of protection technology, a large number of PC protection to the power grid has been put into operation, to the substation secondary circuit has brought a huge technological innovations,like the economic benefits to the grid companies to give a guarantee,and protection is an important guarantee for the safe operation of power grid, so we mandate protection staff will also be imminent.The author analyzes and summarizes years of work experience,describes its characteristics and advantages,and then, on the protection system failure analysis and a comprehensive discussion.
