小型纯电动船舶永磁同步电机控制系统的优化设计

The optimization design of the control system of permanent magnet synchronous motor on small electric ship

随着高能蓄电池和快速充电技术不断发展,现代电动船舶完全可以用在短途的岛际交通运输中,可以实现与电动汽车同样的性能。纯电动船舶的电力推进系统采用蓄电池取代柴油机提供动力,可以避免柴油机产生的废气和噪声对海洋环境造成的污染,极大提高推进系统效率。而影响电力推进系统效率的关键之一就是电机控制器的性能,由于永磁同步电机与其他推进电机相比,具有优越的整体性能,因此本文以永磁同步电机作为纯电动船舶的推进电机,对永磁同步电机控制系统的优化设计展开研究。

With the development high of energy battery rapid charged technology, modern electric ship can completely realize the same performance as the electric cars in short island international transportation. Electric ship electric propulsion system use battery replace the diesel engine as the power supply, can avoid marine waste gas and noise environment pollution caused by diesel engine ,and greatly improve the working efficiency. One of the key factor to the electric propulsion efficiency is motor controller. Because of the high performance of the permanent magnet synchronous motor compared with the other propulsion motor, this article take the permanent magnet synchronous motor as the propelling engine of the pure electric ship, studied on the optimization design of the permanent magnet synchronous motor system.
