摘　　要：根据磁饱和式可控电抗器(MSCR)的结构特点,提出了基于MATLAB多绕组变压器模型的MSCR仿真建模方法。通过对MSCR基本参数关系和铁芯磁化饱和特性的分析,找到了MSCR额定容量、额定电压、额定频率、自耦比和绕组电阻等参数与MATLAB多绕组变压器模型参数之间的定量关系,明确了基于MATLAB多绕组变压器模型的MSCR仿真模型参数的设置方法。实例仿真结果说明,所建MSCR仿真模型不仅可以对绕组、晶闸管、二极管等MSCR元器件的电压和电流,以及晶闸管、二极管之间的换流过程进行仿真分析,而且具有直观简单、不依赖于MSCR结构参数和准确有效的特点。According to the structural features of MSCR（Magnetically Saturation Controllable Reactor）,a method is presented for the MSCR modeling based on the multi-winding transformer models of MATLAB.The basic parameter relationships and the core magnetization saturation characteristics of MSCR are analyzed and the quantitative relationships between the rated capacity,rated voltage,rated frequency,turns ratio and winding resistance of MSCR and the parameters of multi-winding transformer models of MATLAB are obtained,based on which,the method for the parameter setting of the MSCR simulation model based on the multi-winding transformer models of MATLAB is proposed.Simulative results show that,the established MSCR model can be used to simulate the current and voltage of MSCR components,such as winding,thyristor,diode and so on,as well as the commutation process between thyristor and diode.The established model is intuitive,simple,accurate,effective and immune to MSCR structural parameters.
