Modeling of magnetically saturation controllable reactor based on multi-winding transformer models of MATLAB

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.
