摘要
高压输电线路故障的准确定位,能够缩短故障修复时间,提高供电可靠性,减少停电损失。对于占绝对多数的瞬时性故障来讲,准确的故障定位可以找出故障的原因,及时发现隐患,防止事故再次发生。基于小波变换的行波故障测距系统将小波变换引入双端行波故障定位,实现了快速可靠的定位和选相。
Accurate positioning of high pressure transmission line can shorten fault repair time, improve power supply reliability and reduce power failure loss. Accurate fault positioning can find out the reasons of faults, discover hidden danger in time and prevent accident happening again for major transient faults.Traveling wave fault location system based on wavelet transform can introduce wavelet transform to double-end traveling wave fault locating to realize quick and reliable location and phase selection.
