晋北-南京±800kV特高压直流输电工程接地极阻抗监视系统测量环节干扰问题分析

Analysis of measurement interference of the earth electrode impedance monitoring system in Jinbei-Nanjing ±800kV HVDC transmission project

本文对晋南特高压直流输电工程接地极阻抗监视系统测量环节干扰问题进行了深入的分析,结合可能造成干扰的原因,提出相应的解决办法和一些建议,为特高压直流输电工程接地极阻抗监视系统设计施工运行提供依据。

This paper analyzed the measurement interference of the earth electrode impedance monitoring system in Jinbei-Nanjing ±800kV HVDC transmission project. Combined with the possible causes of interference, we put forward some useful resolution and advice. These measures provide the basis of the design, construction and operation of the earth electrode impedance monitoring system in the similar HVDC transmission project.
