谐波谐波harmonics(harmonies)频率为基波频率整数倍的正弦波分量，又称高次谐波。在交流电路中.具有非线性阻抗特性的电气设备(见非线性负荷)向电源反馈高次谐波，导致电力系统电压、电流波形崎变，使电能质盘变坏。近年来，由于电力电子技术的发展，大量换流设备、电子设备等具有非线性阻抗特性的电气设备接人电力系统，造成谐波污染。这些电气设备称之为谐波源，主要有电力机车、电弧炉、整流器、变频器、逆变器、相控调速和调压装置、电焊机、感应加热设备、气体放电灯以及有磁饱和现象的机电设备。谐波的危害性表现在干扰通信线路，使同步发电机额定输出功率降低，感应电动机功率因数下降、转矩降低、损耗增加，变压器温度升高、效率降低，加速电气设备绝缘介质老化，使用寿命缩短，甚至损坏，控制保护及枪侧装t工作精度、可靠性降低等。谐波限制标准见供电质童。
