摘　　要：提出了一种新颖的超高压输电线路故障双端测距精确算法。该算法采用相—模变换技术和分布参数线路模型,考虑了双端数据的不同步问题,运用拟牛顿法迭代求解非线性方程组,仿真计算表明具有很高的精度。A novel accurate fault location algorithm for UHV transmission line was put forward.Based on the phase-modal transferring technique and the distributed parameter transmission line model,the algorithm utilizes quasi-Newton method to resolve non-linear equation sets considering asynchronization for data sampling at both terminals.The simulation results of EMTP showed that the method has high accuracy.
