The transmission line is represented through a cascade of π circuits and the frequency dependence of the longitudinal parameters is synthesized with series and parallel resistors and inductors. The corona effect will be represented using the Gary and Skilling-Umoto models. The currents and voltages along the line are calculated by using state-space technique. To demonstrate the accuracy and validity of the proposed frequency dependent line model, time domain simulations of a 10 km length single-phase line response under energization procedure will be presented. ©2008 IEEE.engCoronaState space methodsTime domain analysisTransmission linesCorona effectCurrents and voltagesEnergizationFrequency dependenceFrequency dependent line modelFrequency dependent transmission linesState-space techniqueTime-domain simulationsTransmission lineBandpass filtersElectric linesElectromagnetic wave emissionTransmission line theoryTrabalho apresentado em evento10.1109/TDC-LA.2008.4641753Acesso aberto2-s2.0-676504934844830845230549223
