Abstract :
A novel iterative method for the analysis of the bipolar ionized field in HVDC (high-voltage direct-current) transmission lines without resort to Deutsch´s assumption is described. The finite-element technique is used to solve Poisson´s equation where the constancy of the conductor´s surface field at the corona inception value is directly implemented in the finite-element formulation. The proposed method has been tested on laboratory and full-scale models. The calculated V -I characteristics agreed well with those calculated and measured before. The dependency of the corona current as well as its monopolar and bipolar components on the conductors´ height is discussed. The simplicity in the computer programming in addition to the low number of iterations required to achieve convergence characterize the proposed method of analysis
