Research on the Stimulation Modeling of Magnetically Controlled Shunt Reactor

The magnetically controlled shunt reactor (MCSR) is a very important reactive power compensation equipment for power grid, which has the function of smooth regulating capacity, eliminating the overvoltage of operation and submersible current. The structure of MCSR is complex, and it works in the saturation state of AC and DC mixing. The modeling is difficult and there are few references at home and abroad. This paper uses Ansoft Maxwell software to build two-dimensional finite element model of MCSR, and the external circuit editor as the excitation source of the finite element model, successfully built a simulation model which is more conducive to analyzing the characteristics of MCSR. This model is more accurate and solves the defects that other methods can't analyze accurately. Then we use this model to analyze the working characteristics of MCSR under the interaction of DC and AC-DC power sources and the working characteristics of capacitor regulation process.
