A TRANSIENT STABILITY SIMULATION PACKAGE(TSSP) FOR TEACHING AND RESEARCH PURPOSES

This paper describes a simulation package for performing transient sta bility study of a power system. The package includes four parts which are a fast decoupled load now program, a short circuit calculation pro gram, a transient simulation program and a plotting program. The simul ation program consists of a coordinator and many modules, each of whic h simulates a power component, a controller or a physical process. Sim ulated results can be displayed on the screen by identifying the compo nents and variables. The package is rich in providing modules for nonl inear representations of power components, though user-defined modules can also be easily interfaced into the package. The three data files are designed in such a way that maximum convenience in data preparatio n is achieved. The package can be used for teaching and doing research related to power system dynamics and control. Application examples an d experience gained with the use of the package are discussed.
