Performance of short transmission lines models

Performance of a short transmission line models is investigated in this paper. The performance accuracy is assessed by considering three dynamic models for the line. Computer simulations show that the results of the dynamic models agree with the results of the standard line model during steady state operations but they disagree with it during transient circumstances. In controlling the level of transients, the paper results recommend that in energizing a line, it is preferable to switch-on the poles of circuit breaker in a sequential manner rather than in a simultaneous manner. Also, simulation results show that transient voltages in a loaded line case are more severe than the unloaded line case.
