Magnetic Equivalent Circuit-Based Simulation of a 6-Phase Generation System

In this research, a dynamic magnetic equivalent circuit (MEC)-based model of a 6-phase wound rotor synchronous generator has been developed. The model is coupled with dual active rectifier bridges to enable detailed switching waveform level simulations of an MVDC generation system. The MEC model of the generator accurately captures time and spatial harmonics as well as saturation of magnetic material and it represents a reasonable balance between accuracy and computation time compared to lumped parameter or finite element models. In this paper, it is shown that the model enables one to efficiently and accurately explore system dynamics and alternative controls under cases in which a single generator sources multiple healthy or faulted buses.
