【Abstract】 A comprehensive model for HV cable, including static electric field and steady current field, is proposed in this paper. Variation for simulation with specific boundary conditions is derived according to the model. Preconditioned Bi conjugate gradient method is implemented to improve the convergence feature of the numerical computation. Finally, this model is used to optimize parameters of HV cables.更多还原
