Abstract
This paper presents a new most complete model for corona analyzing in overhead transmission lines with considering skin effect and conductance originate from corona in PSCAD. The transmission line is divided into adequate identical sections which include nonlinear (voltage dependent) capacitor and resistor branch for corona modeling and series resistor and inductor and shunt capacitor-resistor branch for longitudinal transmission line modeling. The corona discharge is simulated by means of v-q (voltage-charge) curve of the transmission line which can be easily measured or found analytically. Time-domain technique are used for the computation of the power frequency and surge response of a transmission line with corona.
