2、esearch of the integrated power system in domestic is still at the start stage, and there are many problems in the practical application process, therefore, develop the modeling and simulation of the marine integrated po

3、wer system, not only is an innovative work, but also can be used for reference to the development of the marine electric propulsion. The subject is the research of simulated marine Integrated Power System with simulation

4、 software. At the first, this paper analyses structure of marine integrated power system, and bring forward modular thinking. The integrated power system can be divided into three parts: power supply system, electricity

5、distribution systems, and propulsion systems. In Power Supply System, the paper mainly discusses marine diesel engine generating, which analysis the principle of original power machine and generator excitation control sy

6、stem in detail. According to the principle, the mathematical models can be established, and the corresponding simulation module can be set up with the simulation tool. In the propulsion system, first of all, the permanen

7、t magnet synchronous machine (PMSM) mathematical model was analyzed; the SVPWM simulation module was constructed and applied to the vector control simulation. A kind of PI control algorithm was proposed. Appling this alg

8、orithm to the PMSM vector control simulation system can improve the system’s static and dynamic performance to some extent. Second, the computation of ship resistance, the propeller thrust characteristic and the propelle

9、r torque characteristic were studied, and the propeller model was established. According to the structure of the marine integrated power system, setting up two marine integrated power systems simulation model based on th

10、e sub-system simulation model and simulating, analyzing the system. The results show that the simulation system can be used to simulate other marine integrated power systems by changing the parameters of the generator sy

11、stem model, the propeller model and the PMSM vector model. Although some sub-system simulation model is deal with simply when they are set up, but result of simulation and analyses indicate the whole marine integrated po

12、wer system simulation model has good precision, it can well simulated the actual system working conduction in some ways, the result can be look on as prophase exploration. Key words：Marine Integrated Power System, Electr
