| 摘 要： | 针对配电系统中最常见的暂恋电能质量扰动，例如电压暂降、电压暂升、振荡、脉冲等在发生扰动的起止时刻常常对应电压信号的奇异点的特点，本文提出了一种基于小波变换的暂态电能质量奇异性检测方法。利用小波变换的快速算法——Maliar算法来确定暂态电能质量信号的扰动持续时间和扰动波形，从而进行检测。

| Abstract: | Accornding to characteristic of the disturbance signal of power quality such as sags swells oscillation and transient impulse signal that match along with abnormal point of the voltage signal,this text put forward abnormal signal detection of transient power quality based on Wavelet Transform. It use Mallat algorithm to make certain duration and waveform of transient power quality and detect. |
