| Abstract:To solve the problem of high fuel consumption and serious environmental pollution in traditional mechanical propulsion system at low speed maneuvering stage, a four-quadrant ship-diesel-propellers model, and a dynamic simulation model of diesel engine and motor power system were established respectively by using the MATLAB/Simulink and by integrating the advantages of diesel engine drive and motor drive. The comparative analysis was made of the navigating speed response and fuel consumption of pure diesel engine drive and the navigating speed response and power consumption of pure motor drive at low load propulsion. The results of the study show that the power take in(PTI) mode has the advantages of fuel economy, energy saving, environmental protection and high power at low speed maneuvering navigation. The study method can provide a theoretical support and guidance for the research of marine hybrid system. |
