MVCR Performance Improvement Research Based on ANSYS

Abstract

Magnetic valve controllable reactor (MVCR) is a kind of reactive power compensation equipment with good control flexibility and high reliability, which as a result making MVCR being applied more and more widely. Therefore it is crucial to improve the performance of MVCR. In this paper, a method is presented for reducing the fringing effect by dividing one single magnetic valve of MVCR into several series-connected parts, which will reduce the corresponding inductance of AC winding. Consequently the equipment will generate more reactive power with the same working voltage and the control voltage as well as improving its performance. By theoretical analysis and simulation with software ANSYS, an optimal separation of MVCR’s iron-core is presented in this paper which calculates the number of magnetic valves and the space length between every two of them. The validity of this design has been fully confirmed by specific experiments that under the same working voltage and control voltage, the current of the AC winding increases by 7.4% when a single magnetic valve is divided into two parts.
