Ship Electrical Propulsion And Matching Character Of Ship, Engine And Propeller

The history of ship electrical propulsion was almost 100 years, But because of the limitation of technology, It had not been widely used . In the last 20 years , with the development of power electronic technology of ship, electrical propulsion was accepted by many ship owners and shipyard.First of all, the paper has an analysis of ship electrical propulsion technology . Different part of ship electrical propulsion systerm were introduced and researched .The paper has a detail research of Podding and point out that the Podding is certain to be the best choice of our country 's electrical ship power system .The electrical propulsion system was described according to the ship, the propeller, the motor, the engine. The next step is the matching character of ship, engine, drive system, propeller and the principal particulars of electrical propulsion system.The Visual Basic was used as a tool to illustrate the station character of the electrical propulsion system . when the certain parameters of ship, propeller and motor are taken in, the programme will give drawing of the matching of ship, propeller and motor. At the same time , some parmeters will be shown.Mat lab/Simu link lead a superior advantage in the field of simulation , The paper build some modes of electric ship power system including the models of motor and generator derived from Simulink .After the process of model simulation , the dynamic curve of electrical ship were drawn out.After having a summarize of paper , it point out that the next step is to integrate the electrical propulsion system and develop the technology of podding system.
