摘要
利用等效电流的概念得到了磁饱和式可控电抗器比较简明的数学模型。把两个完全相同变压器的一次侧绕组顺串联 ,二次侧绕组反串联 ,得到了磁饱和式可控电抗器的等效电路 ,该等效电路准确反映了数学模型所揭示的物理规律。以Matlab提供的电力系统模块集 (PSB)为平台建立了磁饱和式可控电抗器的仿真模型 ,并用其先进的算法进行了仿真分析。
Introducing the concept of equivalent currents,this paper proposed a very simple mathematical model for a magnetically saturated controllable reactor.When the primary windings of two identical transformers are series agreeing and the secondary windings are series opposing,an equivalent circuit for such kind of reactors can be thus derived.This circuit exactly manifests the physical law of the mathematical model.Based on the power system blockset (PSB)of Matlab,a simulation model for a magnetically saturated controllable reactor is constructed.Subsequently,a simulation analysis is demonstrated.The results confirmed the presented method.
