Abstract:The dual nine-phase energy storage electrical machine is a new kind of multiphase synchronous machine, and the mathematical equation of its main generator is up to 21 orders. when the machine releases energy to load through rectifier, the rotate speed, output voltage and current is constantly changing, and mechanical dynamics is strong coupling with electromagnetic transient, which makes it difficult to analyze with analytical method. Firstly, the equivalent three-phase reduced model is derived to simplify the original model. Secondly, ignoring high harmonics due to the AC side and DC side higher harmonics of rectifier having little influence on the system’s active power transfer and dynamic behavior, considering the function of the ac side variable’s fundamental and dc side variable’s average, the system average model is derived to simplify the original model and promote the computation efficiency further. The equivalent reduced average model of dual nine-phase energy storage generator with rectifier’s load is established in the Matlab/Simulink software, and the effectiveness and correctness of the model is verified by comparing simulation results.
