A multi-protocol based simulation platform of the integrated automation system for the electric traction substation is investigated. The digital, modularization and object-oriented design methods are proposed in this paper, and the ideas of the generalized software-bus and flexible gateway are adopted. Simulation for multiple communication groups and substations can be implemented by one computer or a simulation net formed by multiple computers on the simulation platform of integrated automation. Several optional communication protocols can be applied on this system, and all the simulation functions of the substation integrated automation system have been implemented. The real-time procedure, results of the simulation, and the operating status of the system can be all displayed at the man-machine interface. The operating parameters of the simulation system can be set and modified on line. It is proved that this platform is versatile, flexible and expandable.
