低压并联电容器装置中串联电抗器的选用

Selection of Series Reactors in Low-Voltage Shunt Capacitor Device

目前低压电容器补偿装置大多采用串联电抗器来消除系统谐波及限制合闸涌流。对无源滤波的原理及串联电抗器参数的选取进行了分析,提出了合理的参数选择方法,并说明了串联电抗器对电容器的影响,为电容器的参数选择提供了参考,确保了整个补偿系统的安全可靠运行。

At present, mostly series reactors were adopted in low-voltage capacitor compensating devices to eliminate harmonics of system and restrict the on-off inrush currents. The principle of passive filter and parameters selection of the series reactor were analyzed. A reasonable method to choose the parameters was put fonward, the influence of the series reactor on the capacitor described to provide the reference to some parameters selection of capacitor, so as to ensure that the whole compensation system operates safely and reliably,
