基于小波变换的行波故障测距系统

Traveling wave fault location system based on wavelet transform

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。

By accurate fault location,repair lines time can be cut down, power supply can be provided and power off lost can be reduced. It is also helpful to check out fault reason and deal with shortcoming quickly when transient fault happens. The fault point and fault phase can be located reliably and rapidly with the traveling wave fault location system which combines wavelet theory and two - terminal fault location.
