电力继电保护故障分析及处理

Fault Analysis and Dealing of Power Relay Protection

为提升供电稳定性,促进我国电力行业的发展,指出了电力系统继电保护装置的重要作用,分析了电力继电保护常见的故障类型,即开关设备故障、人为原因故障、电流互感器和电压互感器故障,提出电力继电保护装置故障处理措施。应提升工作人员专业素质,做好安装、检修和维护工作,优化电力继电保护故障处理措施,采用参照处理法、对比处理法、置换处理法和分段处理法,快速找出系统故障位置,准确分析故障原因,尽快恢复系统工作,减小故障影响范围。

In order to promote the power stability,and promote the development of power industry in China,the research points out the importance of power relay protection;analyzes the common fault types,i.e.switchgear,human causes,current transformer and voltage transformer fault;and proposes the fault handling measures of power relay protection device.It is suggested to improve the professional quality of the staff,do well in arrangement,service and maintenance,optimize the failure treatment measures of power relay protection,adopt reference,comparison,replacement and phasing treatment measures to rapidly find out the location of system failure,accurately analyze failure causes,recover system operation as soon as possible,and reduce failure influence scope.
