A Digital Power System Dynamic Simulation System Based on Middleware Technology

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.
