Simulation and experiments on a sparkle model of a current-changing DC generator (DCG)

In order to make the system analysis and research of a certain type ship main converter unit safer and more economical, according to the mathematical model of the main converter unit, the normal working condition and the emergency working condition models of the main converter unit are built based on the MATLAB simulation software. The simulation models are used to analyze the operating conditions of the main converter unit, when the loads are suddenly loading and unloading, the harmonic analysis is performed on the AC voltage by FFT. The simulation results shows that the model can better simulate the operation characteristics of the main converter unit and lay an established foundation for the intensive study of the main converter unit.
