电抗器饱和对短路电流的影响

并联电容补偿装置中的铁芯电抗器的饱和特性对电力系统短路电流产生影响。此影响体现为在短路初期使短路电流增大。其增大的程度与补偿装置接入点距电源的远近，和补偿回路的参数有关。在某些条件下其增值可达２０％以上。本文给出在哪些情况下，选择和校验电器设备时应考虑电抗器饱和的影响。

The nfluence of Reactor Saturation on Short Circuit Current

The saturation of core reactors in the shunt compensation condenser instruments have influence on short circuit currents in electric power system. It increases the subtransient current.The degree of this increase is related to the distance between the compensation sets and sources and is also related to the parameters of the compensation sets. At times the increase of short cricuit current well exceed.20 percent.This paper shows conditions that the saturation influence of core reactors should be considered when we select electric equipments.
