摘　　要：磁控电抗器以其控制灵活、稳定、可靠、可连续调节工作电流等优势在电力系统中得到了广泛应用,但目前对其工作原理的仿真方法存在过于复杂和繁琐的问题。为此,提出了一种基于双饱和变压器模型的磁控电抗器仿真新方法,即采用2个独立的多绕组变压器模拟磁控电抗器的工作原理,通过MATLAB软件对此方法进行了仿真验证。研究结果表明:该方法直观简单,不用考虑电抗器结构尺寸等参数,并能仿真各绕组、晶闸管和二极管等元器件的电压、电流及各绕组的磁链;基波电流(标幺值)仿真值与理论计算值的相对误差小于±1%,证明了该方法的有效性。advantages simulation problem, a Magnetically controlled reactor（MCR）has been widely used in electric power system,which owes to its of flexible control,stability,reliability and continuous adjusting of working current,etc. However, the methods for working principle of MCR are too complex and tedious at present. In response to this new method for simulation of MCR based on double saturated transformers model is proposed in this paper,that is,two independent multi-winding transformers are adopted to simulate the working principle of MCR, which is verified by means of MATLAB software. Research results show that,the proposed method is intuitive, simple,and immune to structural parameters of MCR. The voltage and current of MCR components such as winding,thyristor,diode and so on,as well as the magnetic linkage of each winding,can be simulated using this method. Furthermore,the relative error between simulated and calculated per-unit values of the fundamental current is less than ±1%,which proves the validity of the proposed method.
