【摘要】 建立准确的能效仿真模型是提升和评估船舶能效水平的基础。以1艘内河690客位电力推进游轮为研究对象,在分析了船舶能量传递过程的基础上,结合船舶原理和动力推进装置相关知识,基于MATLAB/Simulink建模仿真软件,建立了对象船舶整体能效仿真模型,并利用船模自航实验数据对模型准确度进行了验证。在此基础上,研究了对水航速、非推进用电、机组模式及通航环境对电力推进游轮能效的影响。研究结果表明:模型仿真结果和船模自航实验数据相比,航速平均误差为0.958%,误差均控制在2%以内;在推进用电一定时,可通过调节非推进用电,使船舶总功率在一个百公里油耗较低的区域,实现船舶能效水平提升。更多还原

【Abstract】 Establishing accurate energy efficiency simulation model is the basis of improving and evaluating ship energy efficiency level.Taking a inland river 690 passenger electric propulsion cruise ship as the research object,based on the analysis of the ship energy transfer process,combined with the ship principle and power propulsion equipment related knowledge,based on the MATLAB/Simulink modeling and simulation software,the overall energy efficiency simulation model of the target ship is established,and the accuracy of the model is verified by the ship model self-navigation experimental data.On this basis,the influence of water speed,nonpropulsion power consumption,unit mode and navigation environment on energy efficiency of electric propulsion cruise ship is studied.The results show that:compared with the experimental data,the average error of ship speed is 0.958%,and the errors are all controlled within 2%;when the propulsion power consumption is constant,the total power of the ship can be reduced to a 100 km area with low fuel consumption by adjusting the non-propulsion power consumption.更多还原
