摘要
提出了同杆并架双回输电线路跨线故障定位的新算法 .算法的故障定位精度不受故障点处过渡电阻、负荷潮流及远端电源内阻抗的影响 .算法利用输电线路本地端的电压电流流数据估计故障距离 .经EMTP仿真验证故障测距的误差小于 1%
A novel numerical algorithm of fault location estimation for two parallel lines on the same tower is presented in this paper.It is based on one terminal voltage and current data.The source impedance of remote end is not involved in the algorithm.The effect of load flow and fault resistance are effectively eliminated on the accuracy of fault location.The algorithm is demonstrated by digital computer simulations and the error in fault location is less than 1 0 0 .
