Modeling Comparison on Control System of Synchronous Generator between DIgSILENT Power Factory and PSASP

PSASP is a widely used power system analysis program in China, and it provides various measured models and corresponding parameters of synchronous generator’s control system. DIGSILENT Power Factory is a popular power system analysis software package around the world. In this paper, some commonly used models in PSASP are established in DIGSILENT Power Factory. The contrast effect is implemented by conducting small perturbation and large disturbance in a two-area four-machine system at last.
