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 。This paper presents a novel accurate two-terminal fault location algorithm for UHV transmission line. Based on phase-modal transformation technique and distributed parameter transmission line model, the algorithm utilizes quasi-Newton method to resolve non-linear equation sets considering data sampling asynchronization at both terminals. The simulation results show that it has high accuracy.
