Abstract:

强工频干扰环境下传统异频法在测量输电线路零序阻抗时存在严重的测量原理错误。针对这一错误,提出了一种测量输电线路零序阻抗的新型异频测量方法。该方法基于GPS技术,同时采集异频电流注入后所有有电磁耦合的输电线路两端的电压和电流信号,在滤除工频干扰信号后,用最小二乘法求解阻抗方程组,得到线路异频下的零序阻抗,再换算到工频下的线路零序阻抗。采用PSCAD软件建立互感线路模型,并用两种异频测量方法进行了仿真测试与比较。给出了采用两种异频法测量某电网220kV同塔双回线路零序阻抗参数的实例。理论分析、仿真测试和实测结果均表明,所提出的新型异频测量方法,测量原理正确,测量精度可满足工程测量的需要。
