Recently, with the advance of technology, big capacity, high quality and automation are the developmental direction of the shipping electric power, and the watch-control system of shipping electric power are widely applied, this require many new and more high technology of the shipping electric power station's design, development and operation. Because the shipping electric power station's performance has very close relation with the operation performance of the original power machine of shipping electric power station and its speed-adjust system, so the simulation of the original power machine of shipping electric power station and it's speed-adjust system is very important. In the background of a prototype of shipping electric power station's original power machine, a mixed simulation system is designed. The main works are:The shipping electric power station's original power machine has been analyzed and researched, and I get the influences from each kind of working state. Through the analysis I have established its static state mathematic model and dynamic state mathematic model. Those models have set up the base of the follow article.On the base of operation characteristic of the shipping electric power station's original power machine its speed-adjust system, I decide the general scheme. Combined with the original static and dynamic state mathematic model, I have established the static and dynamic state mathematic model of the specialty simulation control system. Because the diesel engine and its speed-adjust system is a very complex system, and it's very precise mathematic model is difficult to get. This article has demonstrated the feasibility of model-reference adaptive control in the shipping electric power station's original power machine, and gets a calculation method. This method is right by testified.The author had finished the particular disposal of mixed simulation system,take the whole system as two parts: specialty simulation control system and physical simulation system. As the emphasis of simulation, the specialty simulation control system is composed of two parts: software and hardware. In order too keep the simulation system exactness and real time, the author think over the system integrally and design the system independently. The simulation results demonstrated that the design of the specialty simulation control system is right.Through the simulation's static and dynamic characteristic, the author has analyzed and researched the error in the simulation system. Thought analysis, the error came into being through two ways: the problem of physical simulation part; the cooperation of the numeral simulation system and the physical simulation system (include the interference).
