A transient stability simulation package (TSSP) for teaching and research purposes

This paper describes a simulation package for performing transient stability study of a power system. The package includes four parts which are a fast decoupled load flow program, a short circuit calculation program, a transient simulation program and a plotting program. The simulation program consists of a coordinator and many modules, each of which simulates a power component, a controller or a physical process. Simulated results can be displayed on the screen by identifying the components and variables. The package is rich in providing modules for nonlinear 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 preparation is achieved. The package can be used for teaching and doing research related to power system dynamics and control. Application examples and experience gained with the use of the package are discussed
