超高压电网故障电流限制器晶闸管触发导通试验分析

Conduction Test Analysis of Triggered Thyristor of Fault Current Limiter on EHV Grid

华东电网500 kV故障电流限制器示范工程为世界首次运用,说明了故障电流限制器控制保护系统的基本功能,介绍了华东电力试验研究院承担的部分系统调试工作,包括二次分系统调试的部分内容及调试技术,着重分析了阀组低压触发试验及整组动作时间测量,可为今后类似的工程借鉴参考。

The demonstration project of the fault current limiter on EHV grid of East China Grid is the first of its kind in the world.The paper presents part of system debugging work fulfilled by East China Electric Power Test Research Institute,including part of the secondary debugging of the subsystem and the technology applied,with focus on the analysis of valve bank low-voltage triggering test and measuring of the time involved,so that the debugging technologies can be better used in similar projects in the future.
