Research On Real-time Simulation Of Dynamic Characteristics Of Marine Nuclear-powered Steam Turbine

In company with the application of nuclear energy in marine power plant, the characteristics of steam turbine, essential equipment in power transformation, has been improved greatly. The technique of simulation has been proved a good way in studying dynamic characteristics or improving control system of steam turbine. At the same time, simulation on steam turbine is a part of work of studying marine power plant simulator, which is an important way to be used to train navigating mates. On this background, the dissertation pay attention to study dynamic characteristics of marine nuclear-powered turbine.Simulation on steam turbine focus on steam turbine of power station or power plant, while little attention paid on marine nuclear-powered steam turbine. But marine nuclear-powered steam turbine has great differences with them in structure or working way, so the dissertation summarize available simulation algorithm on steam turbine and come up with mathematical model and dynamic simulation model of marine nuclear-powered steam turbine, which including heat calculation model and noumenon model. On the base of these models, simulation program has been written and debugged. Utilizing related designing date and running the program in real-time operating environment of ASCA, we can simulate dynamically several transient processes, such as accelerating process, moderating process, reversal course etc. We monitor real-time change of each important variable in these processes, give some dynamic simulation results of some important issues, and analyze the simulation results.The dissertation is a helpful attempt in simulation on marine nuclear-powered steam turbine, and .provide a basis for the coming research.
