Abstract:By taking researching into current hybrid power system, a new hybrid system powered by gas turbine and asyn.chronous motor was proposed. Mathematical models of the different parts of the gas turbine and motor power system wereresearched in this paper. Module method was taken to build the simulation model of different parts, including gas turbine,asynchronous motor, synchronous-self-shifting clutch, parallel gear box, parallel controller and propeller, and obtain thewhole system. The simulation model of gas turbine was built by external characteristic; asynchronous motor in method ofcurrent hysteresis band PWM control, and realized flux-weaking control; the S.S.S. clutch model was taken advantage ofwhen paralleling. A strategy to switch between two patterns of shipping was designed, thus leading to the hybrid power sys.tem, a paralleling controller was applied to help paralleling. Researches were taken about the strategy of controlling of twopower and shock when paralleling. It was proved in this paper that the whole hybrid system worked well, the parallel con.troller worked well to reduce the shock and the strategy of paralleling was efficient.
