Research On Simulation Of Steam System In The Marine Engine Room Simulator

The topic of This thesis is one of the sub-projects of the development of Modern Marine Engine Room Simulator Based on Virtual Reality technology, which is one of the " 211 projects" of Dalian Maritime University. As a simulation workstation of Marine Engine-room Simulator, the steam system is mainly utilized to accomplish the process simulation of marine boiler and equipments involved.The accurate models of boiler drum water system and steam pressure controlled system were established in accord with the theory of marine boiler. Through extensive research on simulation technique, this paper selected Tustin transformation to simulate. The response was compared with that obtained through simulation realized by the use of MATLAB and the actual process on different steam flow, feed water flow, fuel flow and control method. The result proved that simulation models are in accordance with the actual process.This thesis also introduces the function of the steam simulation system and how to design its software by employing Visual Basic and MCGS. On the one hand, the steam simulation system can make up a DIS (distributed interactive system) with other sub systems to simulate the actual engine room performance and give trainees comprehensive training. On the other hand, the steam simulation system can be operated alone as a marine boiler training system.In the end of this paper, some preliminary research on the credibility of simulation was executed.
