Abstract

A novel algorithm for calculating HVDC (high-voltage direct-current) corona based on the boundary element method (BEM) is presented. This algorithm takes a different approach to the process of updating the space charge density during the iteration. The iteration process is convergent even for a uniform initial space charge distribution. It takes into account the effect of wind. A variable mobility can be used in the algorithm, which makes it possible to investigate the effects of such parameters as humidity and pollution on the corona
