| 摘 要： | 电力系统理想的电压、电流波形是正弦波。但由于电力系统中存在各种非线性元件,使电压和电流波形发生畸变产生谐波。谐波会造成电网的功率损耗增加、设备寿命缩短、保护功能失常,还会引起变电站局部并联或串联谐振,造成电压互感器等设备损坏。本文综述了谐波的产生、危害及抑制谐波的方法。

| Abstract: | Due to existing various nonlinearity elements in power system, the wave form of voltage and current happen distortion and occur harmonic wave. The harmonic wave brings about the power loss, the equipments life shortening and the protective functions abnormal in power grid, and arousing part connected in parallel or in-series syntony at transformer substation, cause the equipments damages such as voltage mutual inductor. |
