To Achieve Integrated Management Of The Boats Power Plant Modeling And Dynamic Simulation System

Along with the further implementation of reform and opening, and the further prosperity of society, there still exists seriousness of various smuggles, such as marine smuggling. In order to strike down smuggling and to defend our state and family, the technical skills of Marine Police must be enhanced, as well as the ship accidents must be minimized. So a campaign of training is being developed in Marine Police system. With the execution of STCW78/95 code, corresponding equipments for training have been added and developed to guarantee the quality of training, with which the technical skills of Marine Police will be improved. With the continuous development of computer and its widely application in ships, "Simulation trainer" centered by computer simulation is becoming the main technical methodology in Marine Police training, and Marine Police cadets could be certificated by "Certificated Simulator Training" so that they could not only efficiently defense our state, but also further improve their technical skills. Consequently, our university cooperating with Marine Police Academy has researched and developed the marine power plant simulator.Marine power plant is a complex mechanic and electric system. For vivifying implementation of marine power plant simulation and control, six parts, as follows should be done:1. Establishing the mathematical model of diesel generator set;2. Implementing the real-time data test simulation model and I/O interfaces in power plant;3. Investigating power plant integrated management system;4. Establishing human machine interface of each model;5. Devising modules of fault set, analysis, isolation and assessment;6. Suppressing disturbances from surrounding environment.This dissertation is divided into seven chapters, and each chapter's main contents are as follows:In Chapter 1, constitution and characteristic of marine power system, overview of marine power plant, modeling methods and final functions are introduced;In Chapter 2 and Chapter 3, with applying power system stability theory, the analysis and mathematical modeling of the three main components of diesel generator system (generator set, speed governing system and excitation system) are performed, as well as parallel operation condition and implementation of generator set are described;Chapter 4 presents the analysis, modeling and implementation of the loads of three-phase asynchronous motor;Chapter 5 establishes the integrated system and HMI;Chapter 6 covers the modules of fault set, analysis, isolation train and assessment;Chapter 7 summarizes all the tasks the dissertation concerns, presents the shortages in current simulation research and prospects the trend of its development in the future.
