船舶柴电混合动力系统轴带电机不同起动方式的仿真研究

Simulation study on performance of diesel-electric hybrid propulsion system in booster mode

柴电混合动力推进系统的电力推进(PTH)模式是将轴带电机作为电动机运行并单独驱动螺旋桨推进,作为紧急推进的一种有效方式,能加强船舶运行的可靠性。在切换至PTH模式时,轴带电机不能自启动,必须借助其他方式。应用AMESim软件,对船舶柴电混合动力系统进行建模并稳态校核,仿真计算PTH模式下轴带电机不同起动方式对系统性能的影响,研究轴带电机稳定起动的控制策略。仿真结果可为船舶柴电混合动力系统的设计提供参考和指导。

PTH Mode means that shaft generator independently drives propeller in Diesel-Electric Hybrid Propulsion System, which can be used in case of emergency and enhance ship reliability. As shaft generator cannot start by itself, it must rely on other device. This study, based on a verified model in AMESim, simulates the system performance by different starting methods in PTH mode. Moreover, it designs strategies about steady starting of shaft generator. Results of this study can be used as design reference of Diesel-Electric Hybrid Propulsion System.
