摘要
电网中存在的谐波与大量运行的并联电容器组相互作用,会产生谐波放大甚至出现并联谐振,严重影响电能质量和电网的安全经济运行。分析了谐波的危害,对配电网中的补偿电容器组,如何选取串联电抗器电抗值的参数来滤除谐波,抑制谐波电流放大提出了一些看法。
The interaction b operating shunt capacitors wi seriously impact power qualit ween harmonic wave existing in power system and a large amount of make harmonic amplification and even cause shunt resonance . It can and the safe economic operation of the power system. In this paper, the hazards of the harmonic wave were analyzed, and some opinion about how to choose the parameter of series reacter to filter off the harmonic wave and to suppress the amplification of harmonic current was put forward.
