A STOCHASTIC MODEL TO PREDICT RADIO INTERFERENCE CAUSED BY CORONA ON HIGH VOLTAGE TRANSMISSION SYSTEMS

A stochastic model to predict radio interference field as caused by corona discharges on high voltage transmission lines has been developed. This model is based on corona discharge distributed randomly in time and space. A stochastic model for the corona current induced by corona discharges on power lines is proposed. On the basis of the proposed corona current model, a rigorous analysis is presented to evaluate the radio interference (RI) field caused by corona discharges on a single conductor using the stochastic method.
