摘要
在分析串补电容的基础上,提供了判断MOV是否启动的原则和方法,指出目前串补线路故障测距中的一些错误做法。针对中部安装串补电容线路,提出了一种采用贝杰龙(Bergeron)分布参数线路模型、使用双端同步采样数据进行故障定位的新方法,该方法考虑了MOV的非线性,理论上测距精度不受过渡电阻大小及性质和故障位置等因素的影响,大量仿真表明,该方法有很高的测距精度。
Based on the model of series compensated capacitor and its protection, the principle and approach for estimating whether MOV has been operated or not are presented, and some mistakes of locating faults on series compensated lines are pointed out in the paper. A new method for locating transmission lines with series compensated capacitor in the middle is proposed, which uses distributed parameter line model and two-terminal synchronous data, and takes the non-linear of MOV into account. Theoretically, the accuracy of locating faults is free from such factors as fault transition impedance and its property, fault location and so on. Lots of results of locating faults show the high accuracy of proposed fault location techniques.
