Design and technical analysis of 500–600 kV HVDC transmission system for Turkey

Design and technical analysis of an overhead 500–600 kV HVDC transmission system for Turkish Power Transmission System is presented in this paper. Based on the design, resistive losses and corona losses are calculated using analytical formulations. Maximum electric field stress on the conductors is determined by using Comsol Multiphysics Software. Several bundle geometries, conductor types and voltage levels were taken into consideration. A simplified 2D model of the transmission lines, and tower were considered in the electrostatic simulations.
