摘要
超高压输电线路故障测距技术能够缩短故障修复时间,提高供电可靠性,减少停电损失。分析了现代行波故障原理及其系统构成方案,对故障测距技术在湖北500 kV电网的实际运用情况进行了交流和探讨,介绍了行波测距系统在湖北超高压输变电公司的实际运行经验。
In the UHV transmission line,fault distance measure technology can speed up the instauration time, enhance the reliability of power supply and reduce the outage loss. The principle of modern travelling wave fault distance measure and its system constitution scheme were analyzed. The real operation condition of fault distance measure in Hubei 500 kV power grid was communicated and discussed. The operation experience of travelling wave fault distance measure system in HBEPC EHV Transmission ＆ Substation Company was introduced.
