舰船电力推进用发电机/电机驱动器集成优化

基于多级脉宽调制技术的电机驱动器有着高质量的功率输出,加之永磁电动机和先进感应电动机技术使舰船全电力推进得以实现。系统的输入电源通常会选择常规的工频三相交流同步发电机组,然而事实上突破该限制会给推进系统带来更多的好处。发电机和电机驱动器之间的最优化设计会使电力推进系统受益匪浅。本文对使用高频率、高转速、多相和集成整流器的发电机性能和布置优势进行了描述,各种发电机的优化设计使得电力推进系统在尺寸、重量和效率上都得到了重大的改进。

Integrated Optimization of Generators/Electric Motor Drives Used for Marine Electric Propulsion

As motor drive with multi-level Pulse Width Modulated (PWM) architectures has high quality power output, it makes marine full electric propulsion achieved when combined with permanent magnet motor and advanced induction motor technology. The input power selected for these systems is AC synchronous generator, however, it is better for the propulsion system to break through this limit. The electric propulsion system will benefit from the optimal design between generator and electric motor drive. This paper gives the performance and arrangement advantages of generator with high frequency, high rotational speed, multi-phase and integrated rectifier, and the optimal design for generator makes the electric propulsion system a great improvement on dimension, weight and efficiency.
