| 摘 要： | 提出了一种不同于现有故障类型判别的思路,利用小波变换理论分析处理线路单相瞬时性故障和永久性故障。在故障发生后,断路器开断前时间段的暂态信号,通过波形识别区分两种故障。所提判据在时间和准确性上要优于传统的基于故障后线路开关开断后故障线路残压幅值的判别法,并经仿真验证了其正确性。

| Abstract: | This paper presents a different from the existing fault type identification using wavelet transform theory analysis on line transient faults and permanent faults.After the fault of circuit breaker front time of transient signal through the waveform identification to distinguish between two kinds of fault.The proposed criterion in time and accuracy is superior to the traditional based on circuit breaker outage fault line voltage amplitude discrimination method and its correctness is verified by simulation. |
