Squirrel-cage asynchronous machine is used to simulate marine propeller load characteristics.The mathematical model for squirrel-cage asynchronous machine is established in the rotating coordinate system,and the current is decoupled to the directions of torque and field.The torque vector control is used to realize the torque closed-loop control of the asynchronous machine for mechanical load simulation.The simulation model of the mechanical load simulation control system based torque vector control is established by the software MATLAB/Simulink.Considering the interrelationship between the ship and propeller,the starting process and reverse process of some marine propeller are simulated based the mechanical load simulation control system.With simulation results,the mechanical load simulation control system could well simulate the marine propeller＇s reverse characteristics,and the equipment could realize the mechanical load simulation in four quadrants,and it can be used in the mechanical load simulation of reversible system.
