Research Status of Live Working on ±800 kV UHV DC Transmission Lines in Northwest Power Grid

±800kV特高压直流输电线路带电作业能够在很大程度上减少停电时间,避免电网造成不必要的损失,有效维护了电网的安全稳定运行。目前我国在±800kV特高压直流输电线路带电作业技术研究中取得了较大的成果,同时也存在着一定的不足。本文将结合现行带电作业工作经验进行分析,并提出带电作业的技术应用要点。

The live working of ±800 kV UHV DC transmission line can greatly reduce the power outage time, avoid unnecessary loss of power grid, and effectively maintain the safe and stable operation of the power grid. At present, China is working on ±800 kV UHV DC transmission line. The technical research has achieved great results, and there are corresponding deficiencies. It will be combined with the current working experience of live working, so as to put forward the technical application points of live working, and hope to strengthen the ±800 kV UHV DC transmission for the Northwest Power Grid. Understanding of live working on the line.
