A new algorithm for evaluating the fields associated with HVDC power transmission lines in the presence of Corona and strong wind

A novel algorithm for calculating high-voltage direct-current (HVDC) fields in the presence of corona and strong winds based on the boundary element-method (BEM) is presented. The algorithm uses an auxiliary Poisson's equation for updating the space-charge density during the iteration. The iteration process is convergent for wind velocities tested up to 12-m/s. The algorithm can be used for the calculation of ionized fields associated with bipolar HVDC power transmission lines, with some modifications.<>
