摘要
在船舶综合液压推进系统的理论研究层面上,提出主机的恒功率控制.为证明此观点,建立了系统动态数学模型,并基于AMEsim对该系统的主机恒功率控制过程进行仿真分析.结果表明:在船舶综合液压推进系统主机定速运行过程中,当船舶负载发生变化时,通过控制系统对主泵排量的调节,主机的实际功率基本保持设定功率值.因此,船舶综合液压推进系统主机的恒功率控制是合理的.
A constant power control for a main engine is presented based on the results from theoretical study on its integrated hydraulic propulsion system. Verification of the control method was carried out by de- veloping a dynami shows that, even c mathematic model, which was further used to simulate by employing software AMEsim. It though the load of ship has been changed , by adjusting the displacement of the main pump, the actual output power of a main engine running at a constant speed can basically keep the set value where a hydraulic propulsion system has been integrated. It is therefore reasonable that a main engine integra- ting a hydraulic propulsion system emploies a constant power control.
