摘要
随着各种敏感电力电子设备以及非线性负荷的广泛应用,电能质量扰动问题已经成为大家关注的共同焦点。本文介绍了小波变换的基本原理,并将电压中断,电压暂降以及电压瞬变这三种典型的扰动现象通过MATLAB仿真进行分析。
Nowadays, with the wide application of the sensitive power electronic in industry, the power quality disturbance has become a focus that people are concerning about. After the introduction of the fundamental principle of the wavelet transform, the essay does the wavelet transform of the signal of voltage- interruption, voltage-sag, and flicker by means of MATLAB simulation.
