Simulation of transmission line transients using a personal computer

The authors present a technique for investigating traveling-wave phenomena on transmission lines using a personal computer. The transmission line is divided into n segments, each consisting of a series resistance and inductance and a shunt conductance and capacitance. A state model is formulated using the capacitor voltage and inductor currents as the state variables. Trapezoidal integration is used to convert the state equations to a set of linear difference equations which are very sparse. The state variables are updated by solving this set of equations. The technique has been verified using the Electromagnetic Transients Program. Execution times for several test cases indicate that it is suitable for use on personal computers
