摘要
本文论述了小波多分辨率信号的分解 ,并用Meyer小波对电压上升、电压跌落、电压中断、电压畸变、电压瞬变等电能质量干扰的检测进行了仿真实验 ,结果表明Meyer小波在时域和频域上都具有良好的检测性能 。
This paper presents the time-frequency analysis method for detecting disturbance in power quality analyzing. The Meyer wavelet is applied for detecting the swells, sags, interruptions, transients and notches in power quality analysis. The result of simulation illustrates that Meyer wavelet has good performance in time-frequency detecting.
