摘要(Abstract):
文章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 ,仿真计算表明具有较高的精度
This paper presents a novel accurate 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 allowing for data sampling asynchronization at both terminal.The simulation results of EMTP show that it has high accuracy.
