摘要
谐波对电力系统和用电设备产生了严重危害和影响。基于谐波,提出了两种检测方法,经过比较认为小波包变换对电力系统谐波的检测有一定的优势。同时通过仿真结果表明, 该方法能够更加实时有效的检测谐波。
Harmonics is harmful to electric power system and electric equipments. This paper introduces two methods of detecting harmonics. By comparison we find wavelet packet transform has apparent advantages. At the same time, the result of simulation shows that the method can detect the harmonics more accurately.
