摘要
750 kV输电线路主要是跨区联网超高压输电线路,测试750 kV线路参数时,除了测试常规的序参数之外,还需测试750 kV线路的相参数,作为分析暂态过电压和系统建模等相关科研工作的重要数据。青海电力科学试验研究院系统室承担了750 kV宁月Ⅰ、Ⅱ回输电线路参数测试工作,并且首次对750 kV输电线路相参数进行了测试。文章通过750 kV宁月Ⅰ、Ⅱ回线路参数测试方法的介绍及测试数据的分析,得出了正确的750 kV输电线路相参数测试方法和实测数据,作为今后750 kV输电线路相参数测试工作的参考和借鉴。
750kV transmission line is cross-regional interconnection EHV transmission line,in 750kV transmission line parameter test,the phase parameter should be measured besides the normal order parameter,thus provides important data for transient voltage analysis and system modeling.The system and relay protection department of Qinghai Electric Power Test Research Institute has undertook the parameter test of 750kV Ningyue I and II transmission line,and the phase parameter of 750kV transmission line has been firstly measured.The paper introduces test method and analyzes test data of 750kV Ningyue I and II transmission line,and obtains correct phase parameter test method and measured data of 750kV transmission line,thus provides reference for succeeding 750kV transmission line phase parameter test.
