Abstract

Transient voltage surges occur in power systems have caused problem to industrial and residential systems. Therefore, surge protection model was designed to represent the transient surge phenomenon. This project describes the distribution of surge voltage at 3 location categories that are separated by a transmission line. Seven different models of transmission lines are used in the simulations were; ( l)the line is modeled as a single inductor, (2) the line is modeled as a single resistor (3) an ideal transmission line, (4) a cascade of lumped RLC elements where the R value accounts only for the dc resistance of the line, (5) a model with transmission line equations for a continuous line including only the dc resistance, (6) a model with transmission line equations for a continuous line including both dc resistance and the skin effect resistance and (7) a model proposed by Michael F. Stringfellow.The aim of this project is to develop a complete transmission line model and make a comparison that is based on seven different models for low-voltage systems. The simulations were performed with the Alternative Transient Program (ATP). The results of the simulation were compared with both the experimental data. From the simulations, Stringfellow's model produced a satisfactory waveshape of voltage that gives a good representation of the transmission line in low voltage systems.
