New Method for the Transient Analysis of Lines with Corona

  1. Mohamed Mostafa Saied

Abstract

Abstract-- A new direct procedure for the transient analysis of overhead lines under corona is suggested.The governing partial differential equations are derived taking into consideration the possiblevariations in the line’s equivalent conductance and capacitance. A noniterative solution ofthese equations can be found in terms of interpolating functions resulting from a Mathematicacomputer code. The developed program can handle any time waveform of the sourcesinitiating the transients, any line length, design and termination. The transient voltage andcurrent distributions as well as the voltage-charge plots for several case studies are presentedand discussed.Keywords: Computer simulation, corona, differential equations, electromagnetic transients,high voltage, losses, power lines modeling, partial, software
