Abstract: To meet the demand of simulated training for warship and submarine power platforms，the state of arts of marine power training simulation systems is first discussed in this paper，and several fundamental system architectures as well as key technologies in the system design are then investigated. On this basis， by examining a conventional submarine power platform system as a model example，the specific design and implementation technique of marine power training simulation systems are further described in details， which includes the analysis of practical requirements，the overall design of system architecture and software，the modularization modeling methods of real-time performance simulation，the establishment of simulation model libraries，and the design technique of hardware interface systems.
