摘　　要：构建了一种基于通信中间件技术的软总线技术框架,实现了电力系统网络拓扑、继电保护仿真、机电暂态并行仿真等功能模块的协调运行,共同完成电力系统全数字动态仿真。该系统拓展了传统仿真程序的应用功能,可以模拟变电站内部详细的接线变化,可以模拟继电保护的动作过程,可以在高性能计算机群上进行大规模交直流电网的全数字动态实时仿真等,其仿真模型和计算精度与电力系统分析综合程序(PSASP)等同,适用于电力企业进行电网分析计算、教学与培训、电力系统故障再现与分析、连锁故障反应研究、模拟电网运行作为电网调度自动化系统模拟数据源等。A soft-bus technology framework based on communication middleware is constructed to implement coordinated operation of such functional modules as network topology of power system, simulation of protective relayings, parallel simulation of electromechanical transients, thus together with the proposed framework the all-digital dynamic simulation of power system can be completed. Expanding application functions of traditional simulation program, the all-digital dynamic simulation of power system can simulate detailed change of circuit connectivity in substation, simulate action process of protective relayings, and can perform all-digital dynamic realtime simulation of large-scale AC/DC power grid by high performance computer cluster, etc. The simulation models of the proposed soft-bus technology framework is as same as those applied in Power System Analysis Software Package （PSASP） and its computation accuracy is equivalent to that by PSASP. The proposed framework is suitable for power network analysis and calculation, teaching and training, reappearance and analysis of power system faults, research on cascaded failures and their repercussions and simulation of power system operation in power enterprises, and can be performed as data source for the simulation of power grid dispatching automation system.
