A design framework of power system analysis software based on graphical modeling is proposed and established in this paper. It mainly describes the realization method of these technologies, including graphical modeling of power system, automatic generation of the power flow topology, and fault simulation of power system. On this graphical modeling platform, the steady-state simulation of several power system models are studied using the IEEE standard samples data and other typical data, and the accurate fault simulation analysis are also carded out based on the power flow analysis. It's verified that this method could satisfy all the practical demands in operation speed, precision and convergence, which shows the extensive prospects of graphical modeling in the application of power system.
