“科学号”科学考察船吊舱式电力推进系统关键技术

The Key Technologies of the Pod Electric Propulsion System in a Scientific Research Ship

通过对"科学号"海洋科学综合考察船上的吊舱式电力推进系统进行全面的设计和建造方面的分析探讨,剖析交流永磁同步推进电机、直接转矩变频控制策略的结构和特点,分析多相整流谐波抑制技术方案。通过实船验证ABB Compact Azipod吊舱式电力推进系统关键技术在科考船上的成功应用。

The pod electric propulsion system in a marine scientific and comprehensive research ship is discussed about from the views of design and shipbuilding. The structure and characteristic of the permanent magnet synchronous motor（ PMSM） and the direct torque control（ DTC） strategy of PMSM are analyzed,as well as the harmonic suppression methods. The operation of the real vessel proves that the application of the ABB Compact Azipod pod electric propulsion system in the scientific research ship is successful.
