Abstract

Abstract: In order to describe the working conditions of the inverter inductance in actual work more accurately, this paper proposes a simulation model of parallel connection of energy storage converters based on nonlinear inductance modeling. Firstly, the mathematical model of nonlinear inductance based on tan −1 function fitting is introduced, and the equivalent fixed-value inductance model of nonlinear inductance is obtained. Then the suppression method of "PI+R" low-frequency zero sequence circulation is proposed. The simulation results show that the method can suppress low-frequency zero sequence circulation. Finally, the model is established by PLECS, and the method proposed in this paper is verified.
