The Simulation Analysis Of Ship Steam-power Plant Thermodynamic System

Pressure boiler power system can meet the technical requirement of the modern ship power plant well and has better performance in reliable, vitality, economy, weight and size, durability, maintainability and other aspects. Especially the weight and size have evident improvement and the common boiler system can not compare with that. Reducing the power plant can great improve the ship speed and mobility. Therefore pressure boiler power system is one research direction of the modern ship power plant.The article starts with introducing construction, the main working process of the pressure boiler power system, at the same time it texts the strongpoint and easy coming problem of the system comparing to the common power system of the ship.The article provide the predigesting mathematical model by analyzing the construction and the working theory on the basis of the parameter already have get the stable working parameter by thermodynamic calculating.On the basis of mathematical model, the article uses the simulation software—Thermoflex and Matlab to do the research of system simulation, it contains the foundation of simulation model and the analysis of simulation results, at the same time, compare the simulation results with the theoretical analysis results, validate the correctness of the simulation model.The article analyse the match performance of supercharged boiler and gas turbine forced unit. At the same time it analyse the influencing factor of match performance of supercharged boiler and gas turbine forced unit.The article analyse universe performance of supercharged boiler and the requirement of supercharged boiler and gas turbine forced unit and it extraction the path of increasing supercharged boiler performance On the basis of the results of the article and the working request of the pressure boiler power system, the article gives the request of the controlling system for the pressure boiler power system and the research content.
