Abstract: The structure of synchronous generator and improved Park equation based on dq0 reference frame was introduced to get the equivalent circuit after adding the compensating reactance in the work, and the state space model can be set based on the modern controlling theories. Comparisons of the loading effects were made between simulation results and actual data obtained from an aeronautic synchronous generator, the results show that the identified model is valid to reflect the real-time loading effects.
