| 摘 要： | 对电压波动和闪变进行有效监视与管理,首要任务是要准确提取电压波动信号。通过仿真,详细比较了平方检测法、H ilbert变换法、小波分析法用于平稳及非平稳的电压波动信号检测时各自的优越性。结果表明,平方检测法和H ilbert法更适用于检测平稳的波动信号,对于谐波污染较大的非平稳信号,用小波分析法则能够得到良好的检测结果。

| Abstract: | The most important issue of restraining and supervising the voltage fluctuation and flicker is to track the signal.This paper focuses on comparing respective advantage of three methods including square examination,Hilbert transform,wavelet analysis by simulation.The results show that the methods of square examination and Hilbert transformation are more suitable for the examination of smooth signals with low harmonics,and wavelet analysis can give desirable results from the non-smooth and high-harmonic signals. |

| Keywords: | voltage fluctuation and flicker square examination Hilbert transform wavelet transform |
