Abstract

This paper proposes a dynamic iteration method for steady-state corona simulation, featuring adaptive amplitude increase control of the boundary charge density iteration based on electric field fluctuations. Combined with the decoupled solving of the electric potential and charge transport equations, the method enables stable, rapid simulation of 3D corona discharges. Simulation validations on typical rod-type and twin-rod dischargers demonstrate that the proposed method exhibits stable and fast convergence, as well as high efficiency of decoupled solving. Also, the volt-ampere characteristics and the inception voltage obtained by simulation are in good agreement with the measurement. Simulations under typical cross-wind field conditions further confirm the proposed method still maintains good stability and convergence. Additionally, the simulated volt-ampere characteristics agree well with the empirical formulas.

一种基于边界电荷密度分布迭代增幅控制的稳态电晕放电模拟方法

提出了一种基于电场波动的边界电荷密度迭代自适应增幅控制的稳态电晕模拟动态迭代方法。结合电势和电荷输运方程的解耦求解，该方法能够稳定、快速地模拟三维电晕放电。对典型杆式和双杆式放电装置的仿真验证表明，该方法收敛稳定、速度快，解耦求解效率高。仿真得到的伏安特性和起始电压与实测结果吻合较好。在典型横风场条件下的仿真进一步验证了该方法仍保持良好的稳定性和收敛性。此外，模拟的伏安特性与经验公式吻合较好。
