摘要
对电力推进船舶中异步推进电机的控制问题展开研究,在MATLAB中分别建立异步电机的矢量控制模型、直接转矩控制模型以及异步电机互馈系统模型,并采用异步电力测功机模拟船舶的螺旋桨负载特性给推进电机提供螺旋桨负载.在实验室条件下应用变频器、PLC、上位机WINCC搭建相应的实物系统,仿真与试验研究验证了该方法的有效性.
Aiming at the control problem of asynchronous pro-pulsion motor in electric propulsion ship , the simulation mod-els of asynchronous motor vector control , direct torque con-trol, and reciprocal power-fed motor platform were built with MATLAB.Moreover, the asynchronous electric dynamometer was used to simulate the ship propeller load characteristic , so as to provide the propulsion motor with propeller load .A physical system including frequency converter , PLC, PC WINCC was built under laboratory conditions .Simulation and experiment results verify the effectiveness of this approach .
