磁控电抗器原理及其在SVC中的应用

Research on MCR and Its Application in SVC

新型磁控电抗器是一种交直流同时磁化的可控饱和度的铁芯电抗器,工作时,可以用极小的直流功率来控制线圈铁芯的饱和程度,从而控制其感抗值和注入电网的电抗电流大小,达到平滑调节电网无功功率的目的,近年来,MCR以其优良的综合性能在静态无功补偿装置中得到了广泛的应用。

Magnetically Controlled Reactor （MCR） is a new type of saturable-core reactor. Its core field can be magnetized by ae and dc current simultaneously. The core saturation can be controlled by the minimum dc power. Therefore, the reactive power of the system can be smoothly regulated by changing its inductance and injecting reactive current. Due to the agglomeration of its advantages, MCR is widely used in the Static Var Compensator （SVC） system in recent years.
