摘要：
This paper presents a new algorithm to simulate the surge corona of power transmission lines in two dimension. The charge simulation method and the finite element method are applied to calculate the electric field, while a time-dependent upwind difference algorithm is applied to calculate the migration of the space charges. The implementation of boundary conditions and the choice of mesh size and time step are discussed to ensure the stability of the proposed algorithm. The Q-V (charge-voltage) curves of impulses applying on single conductor and bundle conductors in a cage having a square cross section are calculated. The simulation results are supported by the published experiments.
