摘要
谐波对输电线路及用电设备有严重影响和危害,小波变换为电力系统谐波分析提供了有力的数学工具,仿真结果表明,小波变换能快速而准确地将信号中的基波信号和不同频率的谐波信号分解出来,从而达到检测谐波的目的。
Harmonic wave has a harmful impact on power system and electric equipments. Wavelet transform provides a powerful mathematical tool for power system harmonic wave analysis, simulation results show wavelet transform can quickly and accurately decomposes the signal into the fundamental signals and harmonic wave signal, so as to achieve the purpose of harmonic wave detection.
