Abstract :
A state-variable technique for teaching power system transients using a personal computer is discussed. Transmission lines are divided into a series of pi-section segments. Each segment consists of a series resistance and inductance and a shunt conductance and capacitance. Using this line representation, a state model is formulated for the power system using the capacitor voltages and inductor currents as the state variables. The state equations describing the system are transformed to a set of linear difference equations through the use of trapezoidal integration. The state variables are updated by solving this set of equations. Nonlinear elements such as surge arresters can be included in the analysis. The technique utilizes the student´s knowledge of network theory and is easily implemented on a personal computer
