| 摘 要： | 当系统中存在谐波源时,无功补偿电容器组与系统电路会在某次谐波频率下发生并联谐振。本文分析了谐振次数与电容器组容量、母线短路容量以及母线电压上升值之间的数学关系。并联电容器组与电抗器串联具有滤波功能,同时也会与系统发生并联谐振。还分析了滤波次数和发生谐振次数的数学关系。

| Abstract: | When harmonic sources exist in power system, parallel resonance occurs due to the interaction between shunt capacitor bank and system inductance. The equation is given which explains the relation between resonance frequency and capacitor bank capacitance, bus short-circuit capacitance and bus rising voltage value. Shunt capacitor bank in series with inductance can filter harmonic while resulting in parallel resonance. The paper also gives the formula on the relation between filtered harmonic frequency and parallel resonance frequency. |
