船舶电力推进系统中异步电动机DTC系统的仿真

Simulation of Speed Control System for Asynchronous Motor Direct Torque Control in Marine Electric propulsion system

针对电力推进船舶中主推进电动机的调速控制环节,对目前最新的控制技术———直接转矩控制的基本组成和工作原理进行分析,在此基础上建立异步电机直接转矩控制系统的仿真模型,利用SABER软件对模型进行仿真试验,仿真结果验证了该模型的正确性和该控制系统的有效性。

This paper analyzes the newest control technology of asynchronous motor in marine electric propulsion-basic structure and the working principle of the direct torque control system of asynchronous motor. The SABER model of the DTC speed control system is established and the simulation results proves that the model is correct and the control system is effective.
