Research of Power System's Simulation Based on Simulink

This paper introduces how to build up a Power System's model in the Matlab / Simulink environment based on it's circuit mechanism.The system processes on idle load when three-phase short circuit fault occurs on the bus.Research results show that the performance obtained from the model is consistent with those obtained from theoretical calculations.Nevertheless,simulation results also show that modeling and simulation by using Matlab/Simulnk play an important role in understanding the theory of power system's operation.
