一种高压输电线路中端故障测距方法的研究

寻找简单快速的高压输电线路故障测距方法是电力系统亟待解决的问题,提出中端故障测距方法,将故障测量装置装设在输电线路中间,测量原理与单端测距算法相同,需要中端电压、电流量,实时求出故障距离。并用PSCAD仿真软件将单端测距与中端测距进行比较,结果表明中端测距较单端测距具有一定的精确性。

Study on Mid-Ended Fault Location for Hi -Voltage Transmission Line

Looking for a simple and fast fault location algorithm of high-voltage transmission line is a problems to be solved. This paper presents the mid-ended fault location method, the fault measuring device is installed in the middle of the transmission line, it is the same as the calculation method of the single-ended fault location. It needs the voltages and currents in the middle of the transmission line and calculates the fault distance at real-time. PSCAD simulation software compares the mid-ended fault location method with the single-ended fault location, the results show that the mid-ended fault location method has more accurate quality.
