电网电容器组谐波谐振和谐波放大的研究

在电力系统运行着大量的并联电容器组，由于电容器的阻抗呈现容性，它与电力系统中的谐波容易产生相互影响，发生谐波的并联谐振或串联谐振和电容器对谐波电流的谐波放大，造成电容器和电气设备的损坏。因此研究和分析谐波对电容器的危害，认识电容器对谐波电流的放大作用，合理地配置电容器和电抗器，以避免电气参数匹配发生谐振，控制其谐波电流放大。

Study on Harmonic Resonance and Harmonic Enlargement of Power Network Capacitor Bank

A great amount of shunt capacitor banks are running in power system.Because of their capacitive impedance and their interaction with power system harmonic,the shunt resonance or serial resonance of harmonic is produced and the harmonic current enlarged.It will damage capacitors and electrical devices.In order to avoid resonance produced by electrical parameter match and to control harmonic current enlargement,the effect of capactior on it and the reasonable disposition of capactior and reactor should be studied.
