摘要
综合电力推进系统广泛应用于豪华邮轮,但其能效不高,需要进一步开展高效推进系统研究以提升综合能效。同时,为应对日益严格的船舶废气排放法规,有必要制定相应的排放控制策略,以满足排放控制要求。以一艘五万吨级中型邮轮为研究对象,对其原柴油电力推进方案和液化天然气(Liquefied Natural Gas,LNG)电力推进替代方案进行仿真计算,分析其经济性、排放性、燃油消耗以及船能效设计指数(Energy Efficiency Design Index,EEDI)和船舶能效运营指数(Energy Efficiency Operation Index,EEOI)等指标,并通过九标度法对各方案进行综合评估,为选择高效的动力系统方案提供参考。
Integrated electric propulsion system is widely applied in cruise ships. However,further research on efficient propulsion systems is needed to improve the overall energy efficiency. At the same time,to cope with the increasingly stringent ship exhaust emission regulations,it is necessary to formulate the corresponding emission control strategies to meet the emission control requirements. In this paper,the original diesel-electric propulsion scheme and LNG electric propulsion alternative scheme of cruise ship are simulated and calculated to analyze their economy,emissions,fuel consumption,EEDI and EEOI and other indicators,and the comprehensive evaluation of each scheme is carried out through nine-scale method,which provides reference for the selection of efficient power system scheme.
