The Simulation And Modeling Of Some Marine Steam Power System

Marine steam power system, which is complex and has numerous equipment, is an energy switch system. On account of the especial working condition, marine steam power system has many characteristics such as small inertia, great dynamic variety, much correlative and restrictive factor between its subsystems etc. So, it is necessary to study the dynamic modeling of marine steam power system.This paper modeled and simulated about some marine steam power system. Because of the particularity and complexity of boiler model and the characteristic of JTopmeret model, the marine steam power system model can be divided into four parts, that's boiler body, air supply system, oil supply system and steam-water (except boiler body)system. The boiler body is modeled by Compaq Visual Fortran language, it's composed of furnace chamber heating power calculation model, evaporates system dynamic model, expansion coil model, superheating system dynamic model and economic system model etc; the other three parts is modeled by JTopmeret, which is a tool of graphics automatization modeling, main model include turbine model, condenser system model, water supply system model, air supply system, oil supply system etc. Finally, the two type models are integrated and debugged in the GSE which is a great simulation platform, and simulated under steady state and dynamic disturbance under steady state.The result of simulation experimentation indicate that the steady state of the model and dynamic disturbance process under steady state is in accordance with actual instance, and validate the rationality and correctness of the simulation model and arithmetic...
