Abstract

A continuous and reliable electrical energy supply is the objective of any power system operation. Electricity is the driving force behind industry and subsequently economy. There are various types of faults appear in power system. Faults can appear due to bad weather conditions, equipment damage, equipment failure, environment changes and many other reasons. Any occurrence of a fault should be detected and cleared by the protective relaying devices. Fast and accurate fault location is a key task for accelerating system restoration, reducing outage times, and hence, improving system reliability. The aim of this project is to develop a two stage fault location algorithm that can determine the distance to the fault. The proposed two-stage fault-location algorithm is applicable for transposed and untransposed transmission lines and is independent of the fault resistance and source impedances. The synchronization angle is determined by using Newton-Raphson method. The maximum error reached from this algorithm is less than: 0.18% for LG faults, 0.20% for LL faults, and 0.26% for LLG faults.

一种用于输电线路故障定位的两级故障定位算法

连续可靠的电能供应是任何电力系统运行的目标。电力是工业和经济背后的驱动力。电力系统中出现了各种类型的故障。故障可能由恶劣天气、设备损坏、设备故障、环境变化等多种原因引起。任何故障的发生都应由继电保护装置检测并清除。快速准确的故障定位是加快系统恢复速度、减少停机时间从而提高系统可靠性的关键。本课题的目的是开发一种两阶段故障定位算法，可以确定到故障的距离。所提出的两级故障定位算法适用于转置和非转置输电线路，且不受故障电阻和源阻抗的影响。采用牛顿-拉夫逊法确定同步角。该算法最大误差小于:LG故障0.18%，LL故障0.20%，LLG故障0.26%。
