| 摘 要： | 小波变换是一种变分辨率的时频联合分析方法,可以对时域和频域信号进行精确地分析。利用小波变换对电网中的谐波电流检测原理进行了分析,通过将电网电流信号分解到各个频带,将基波电流与谐波电流分离,从而达到检测电网谐波电流的目的。仿真实验表明,小波变换谐波检测可以有效地排除电压失真的影响,具有较高的检测精度。

| Abstract: | A method for harmonic current detecting in power system based on wavelet transform is proposed. Through wavelet transform, the fundamental current is separated from power current and the total harmonic current in power system is achieved. A simulation shows that this method is of high precision and can eliminate the effect of power voltage distortion. |
