✦ Synopsis

The modified Gaussian algorithm is introduced for solving the ionized fields of unipolar HVDC lines including the effect of wind. Specific techniques of incorporating in the algorithm the special structure of the optimization problem of the ionized field have been developed to economize the requirements for the computer memory and CPU time. Numerical tests are carried out on a coaxial cylindrical geometry and on a line-plane geometry both in the absence and in the presence of wind. Comparison with available experimental data shows good agreement.

In this paper, a finite element method for solving ionized fields is developed based on a novel solution philosophy. Employing the Galerkin finite element method, the solution problem of an ionized field has been formulated as an optimization problem, i.e. as a problem of minimizing an objective fun
