Unloading Performance Analysis of Main Generator in Aeronautic AC Power Supply Based on Ansoft

Equivalent magnet circuit method is adopted in investigating main generator in three-level synchronous generator system of aeronautic AC power supply. With RMxprt software of Ansoft corporation, it establishes geometrical model and computes primary electrical parameters. Furthermore, with Maxwell 2D software, it attains two-dimensional transient model and simulates magnetic spacial distributing, electromagnetic and circuit parameters under unloading. With contrast to actual measure values, it verifies the correctness of the model. It has been proved available for element encapsulation in further study for other types of aeronautic power supply computational auxiliary design and optimization.
