摘　　要：跨区域互联电网的逐步实现,使得与之相应的电力通信网的覆盖范围越来越广,网络架构日趋复杂,现有集中式仿真的计算、存储资源有限,无法满足电力通信网的仿真需求。提出面向电力通信网的分布式仿真系统,利用EXata网络仿真器构建仿真子系统、数据分发服务(Data Distribution Service,DDS)中间件实现仿真子系统间的数据交互,并基于预定义同步时间点的方式同步推进仿真子系统的仿真过程,使各子系统能够协同完成整体网络的仿真。仿真结果表明,相对于集中式仿真,所提出的分布式仿真系统仿真效率更高,能够支持大规模电力通信网的仿真。With the gradual realization of cross-regional interconnected power grid,the corresponding power communication network has wider coverage and more complex network architecture.The existing centralized simulation of limited computing and storage resources cannot meet the simulation requirements of large-scale power communication networks. A distributed simulation system for power communication networks is proposed.The system uses EXata network simulation software to build simulation subsystem and Data Distribution Service(DDS)to realize data interaction between simulation subsystems,and advances the simulation process of each subsystem based on the predefined synchronization point,so that each simulation subsystem can collaboratively complete the simulation of the whole network.The simulation results show that compared with the centralized simulation,the distributed simulation system proposed in this paper has higher simulation efficiency and can support the simulation of large-scale power communication network.
