基于同步相量测量的线路参数在线测量的实验研究

Studies on Lines' Parameters Measurement Based on Synchronized Phasor Measurement

介绍了一种基于同步相量测量的输电线路参数在线测量的方法。该方法是应用GPS卫星时钟为同步时钟的PMU测量线路的电压、电流同步相量 ,通过计算得到各序线路参数。与传统线路参数测量方法相比 ,具有设备简单、易于操作、不影响正常供电等优点。

In this paper, a new approach to transmission lines' parameter measurement is proposed. It adopts GPS as synchronizing time of phasor measurement unit, and obtains three sequence lines' parameters by computing voltage and current phasors. Compared with the traditional methods, this method is more convenient and no more require line tripped.
