摘要
大规模复杂模型电磁场数值仿真问题一直是计算电磁学中比较难处理的问题。本文采用三维自适应有限元并行求解算法处理此类问题,以某±660kV换流站阀厅全模型电场模拟为例,对阀厅内部关注区域金具表面电场进行仿真计算。并行计算结果与串行计算结果相吻合,验证了本文提出的并行求解算法的正确性和可行性。该并行求解算法,可以显著提高求解速度,实现对于大规模复杂电磁问题的高效数值模拟。
Numerical simulation model of electromagnetic field is of large-scale and complex always difficult problem in electromagnetic calculation. In this paper, a parallel algo- rithm for 3D adaptive finite element method is used to deal with this kind of problem. Taking the simulation of full model of the valve hall for a ± 660kV converter station as example, the electric field value on the surface of fittings in each interested region is calculated. Parallel computation is well consistent with the results of serial computation. So the correctness and feasibility of proposed parallel algorithm is verified. This parallel algorithm can improve calculation speed obviously to realize efficient numerical simulation for large-scale complex electromagnetic problems.
