摘要
梳理了现阶段南方电网公司对变电站二次抗干扰措施的要求。从室内、室外二次接地网及其连接部分着手,详细说明了某超高压变电站实际排查情况及整改措施。提出根本的排查思路是全站应形成二次等电位接地网。整改后的变电站二次接地网效果良好,保护运行平稳。
This paper introduces the requirements of China Southern Power Grid Company on the secondary anti-interference measures for substation in the current stage. It sets out from the indoor and outdoor grounding networks and their connection parts, introduces in detail the the actual inspection situation and rectification measures of the specific substation, suggesting that the basic troubleshooting idea is to form an equipotential grounding network of the whole substation. The modification of secondary grounding network of the substation has obtained good effectiveness, which ensures the smooth operation.
