摘　　要：应用伴随模型方法建立了滤波器电磁暂态仿真的基本模型,在分析换流站实时仿真需求的基础上提出了滤波器的简化模型,并对模型优化的加速比进行了分析。仿真实验结果表明,简化模型在确保计算精度的基础上,显著提高了计算效率,在实现换流站实时电磁暂态仿真方面发挥了重要作用。By use of companion model a basic model of filters for electromagnetic transient simulation is built, and based on the analysis on the demand of real-time simulation a simplified model of filters is put forward, and the speed-up ration in model optimization is analyzed. Simulation results show that under the presupposition of ensuring calculation accuracy the simplified model can evidently speed up calculation efficiency and plays an important part in the implementation of real-time electromagnetic transient simulation for converter substation of HVDC power transmission.
