摘　　要：为提高FRTDS的仿真规模,本文提出一种仿真脚本优化方案及指令流生成策略。在仿真脚本生成过程中,以子网络的预计算方法、框架网络的求解方法为优化对象,以仿真脚本的执行时间最短为优化目标,采用遗传算法对仿真脚本进行了综合优化。在指令流生成过程中,采用兼顾最晚执行时间和通信距离的多批次策略选择待执行任务及其运算核,按照通信资源消耗量确定待执行任务的数据源及其传输通道,减轻通信资源匮乏对仿真脚本执行时间的影响。对含106电平双端PFB-MMC交直交电力系统进行了实时仿真,验证了所提方法的有效性。To improve the simulation scale of a field programmable gate array(FPGA)based real-time digital solver(FRTDS),a simulation script optimization scheme and an order stream generation strategy are proposed in this paper.During the process of simulation script generation,the precomputation method for sub-network and the solution method for frame network are taken as the optimization objects,the shortest execution time of the simulation script is taken as the optimization goal,and genetic algorithm is used for the comprehensive optimization of the simulation script.During the order stream generation process,a multi-batch strategy that takes into account the latest execution time and commu⁃nication distance is used to select the tasks to be executed and their operation cores,and the data sources of tasks to be executed and their transmission channels are determined according to the communication resource consumption,thus mitigating the impact of the lack of communication resources on the execution time of the simulation script.Real-time simulations of a 106-level double-ended PFB-MMC AC-DC-AC power system are carried out to verify the effectiveness of the proposed method.
