变电站继电保护二次回路的在线监测及故障分析

Online Monitoring and Fault Analysis of Relay Protection Secondary Circuit in Substation

在电力发展智能化程度逐渐加深的背景下,变电站的强效保护成为电力工作的重中之重。实际开展过程中传统模式基本以二次接线为主,依赖于继电保护设备之间的彼此协调和人员的监督维护,但这已经不适合当下的变电站发展趋势。为了提升保护装置运行的安全性,本文针对二次回路展开在线监测,详细分析其故障问题,进一步提升智能化变电站的整体运维水平,促进变电站实现全方位持续性发展。

Under the background of the gradually deepening degree of intelligence of electric power development,the strong protection of substation has become the top priority of power work.In practice,the traditional mode is mainly based on secondary wiring,which depends on the coordination between relay protection equipment and the supervision and maintenance of personnel,but this is not suitable for the current development trend of substation.In order to improve the safety of the protection device,this paper carries out online monitoring for the secondary circuit,analyzes the fault problems in detail,further improves the overall operation and maintenance level of the intelligent substation,and promotes the all-round and sustainable development of the substation.
