Abstract
Electromagnetic transient calculation method based on time domain transformation takes advantage of the special characteristics of voltage and current in power systems, whose waveforms are close to be sinusoidal. It can use a larger time step and improve the efficiency of simulation without accuracy loss. To accurately and efficiently simulate the dynamics of power systems related to generators, a synchronous generator model based on the time domain transformation method is developed in this paper. Diverse test cases are used to verify the validation of the presented model. Test results show that the accuracy of the presented model keeps good even with time steps of milliseconds.
