| 摘 要： | 1000kV晋东南(长治)—南阳—荆门特高压交流试验示范工程是我国第1个1000kV电压等级输变电工程,测试并掌握该工程的架空地线感应电压水平对特高压交流线路的设计和安全运行具有重要意义。为给我国后续特高压交流线路提供基础参数,1000kV晋东南(长治)—南阳—荆门特高压交流试验示范工程的系统调试期间,在不同输送功率和单相瞬时人工接地故障工况下,对架空地线进行感应电压测试。通过测试,得到1000kV晋东南(长治)—南阳—荆门特高压交流输电线路的架空地线稳态感应电压水平和暂态感应电压水平。计算结果与测试结果基本符合。对测试结果和架空地线运行方式进行了分析。分段绝缘一点接地的运行方式可大大降低线路损耗。

| Abstract: | 1000 kV transmission pilot project from Jindongnan (Changzhi) to Jingmen is the first 1000 kV transmission project in China. It is important for designing and operating UHV power line properly to test and know the inductive voltage level of the project. The inductive voltage on overhead ground wire was tested,during the period of system test on 1000 kV transmission pilot project from Jindongnan (Changzhi) to Jingmen at different power and in the artificial single grounding fault,respectively. Constant and t... |
