The realization of the virtual synchronous generator based on the park model

[摘要] In this paper, a kind of virtual synchronous generator control algorithm is proposed that can accurately simulate the external characteristic of a synchronous generator. This algorithm based on the synchronous generator park mathematical model considers the motor salient pole effect and the influence of damper windings. Using two-step Adams method to solve the mathematical model of the synchronous motor for current of the motor's port, the converter is controlled to track the current so that the output status values have the same port characteristics with the actual motor. Simulation results verify that in many typical working conditions such as the synchronous motor starting, the output voltage mutating or the frequency changing, the converter controlled in the above algorithm can mimic a real synchronous generator.
