Characteristic simulation analysis of three-phase magnetic valve type controlled reactor

提出了一种能根据电力系统变化而平滑调节自身容量的三相磁阀式可控电抗器(MCR)。简单介绍了其在电力系统中的应用、结构、工作原理及电磁特性,并采用Ansoft Maxwell 3D有限元分析软件进行了电磁仿真分析。仿真分析证实了改变可控硅导通角能改变控制电流大小,从而平滑调节MCR自身容量的可行性。

This paper presents a three-phase magnetic valve controlled reactor （MCR） whose capacity can be smoothly adjusted with the change of power system parameters. Its application, structure, the working principle and electromagnetic characteristics in power system are introduced briefly, and it is simulated using Ansoft Maxwell 3D finite element analysis software. Simulation analysis confirms that changing controllable thyristor conduction angle can change the current, which proves the feasibility of a smooth adj ustment of capacity of MCR.
