Research of Integrated Power Propulsion System Simulation Based on PSCAD

Abstract:

Modeling and simulation of generator, frequency converter, motor, propeller of integrated power system in PSCAD environment respectively, finally form a complete system, which contains the diesel engine and speed regulation system, generator and excitation system, motor and vector control system. Establish the propeller model as motor load by Fortran language. The motor load constantly changing, traditional PI controller parameters are not easily adjusted in real time, SNAPID controller based on the error changes in the changing, complete SNAPID controller in MATLAB environment and call MATLAB continually, the control effect of speed is improved in the process of marine propulsion. Finally simulate typical working condition of system, the simulation results show that propeller shaft torque is smaller when grading operating, the influence of electric propulsion system is smaller and conducive to maintaining the stability of the system.
