摘要
推进系统是舰船的动力来源,随着大功率交流电机和变频调速技术的出现,船舶动力装置中电力驱动技术逐渐兴起,并因其功率稳定性、无污染等优点获得了一定的市场份额。永磁同步电机是舰船电力推进系统的核心,而无速度传感器、矢量控制器等是电力推进系统的关键组成部分。本文首先建立了船舶动力系统的函数模型,在此基础上研究了无速度传感器DTC在舰船推进系统的应用,并进行了电机转矩的仿真分析。
Propulsion system is the power source of ships.With the emergence of high-power AC motor and variable frequency speed regulation technology,the power driven technology of ship power plant is gradually rising,and has gained a certain market share because of its power stability and pollution-free.Permanent magnet synchronous motor(PMSM) is the core of the ship electric propulsion system,and the speed sensor and vector controller are the key components of the electric propulsion system.In this paper,a function model of ship power system is built.Based on that,the application of speed sensorless DTC in ship propulsion system is studied,and the simulation analysis of motor torque is carried out.
