谐波对电网阻抗的影响及抑制方法

Effect of Harmonics on Impedance in Electricity Network and the Depression Measures

高次谐波对电网质量的影响及如何抑制谐波是目前急需解决的重要课题。从理论上分析了谐波对变压器阻抗、输电线路阻抗、负荷阻抗的影响，同时提出了几种抑制谐波的方法。

Effect of high freclueilcy harmonies on electricity network and the measures fordepressing harmomics are important probiem to be soived urgentiy at present. Influences of har-monics on imped;lnce of sransformer, transmission line and load are analyzed theoretically, at thesame titne, sereral ways for depressing harmonics are put forward.
