Application of MATLAB in the Simulation of Power System

Power system is becoming more and more complex along with the development of technology, and it is very necessary that electric engineers study and research by using software for simulating power system. The author first introduces the development history, composition and function of MATLAB. Then the author analyses the effective usages of MATLAB in power system from program simulation and graphics simulation by using two simple examples. On the basis of utilizing the existing models, the particular, complicated power systems can be simulated effectively through combining the two simulation measures and using equivalent circuit means. So mastering the program simulation and graphics simulation is the base for electric engineers to study MATLAB well. Compared to lots of excellent simulative software in power system, MATALB has the characters of studying easy, strong functions and good expansibility and is a very important tool in the simulation of power system.
