ABSTRACT
This paper describes a new method of the corona loss in bipolar HVDC and HVAC transmission lines using Finite Element Method (FEM). The present method implements the potentials and field at conductor surface as boundary conditions. In present method programming calls for only one loop and a new approach for updating of space charge densities around the conductor is implemented using Rung-Kutta integration method. Fast convergence and reduction iteration numbers is characterized of the proposed method. In addition to in this paper in the one case study the corona loss calculation in HVAC lines implemented with this methods and another case study was performed with the RMS value of applied voltage and simulation was performed similar to in HVDC unipolar lines.
