Transient Stability Simulation of Power System Based on Matlab

The basic characteristics of power system transient stability, the function and feature, and mathematical model of power system blockset and Simulink based on MATLAB are introduced in the paper. MATLAB SimPowerSystems are used to build up Simulink models of a three-machine system. Powerful functions of Matlabinthesimulationofpowersystemareshownbythesimulation of power system failure. The result shows that the dynamic behavior of power system during transient processes can be observed quite accuratelyanddirectly.
