| 摘要:以柴油机推进的内河巡逻船为研究对象，将其改造为甲醇-电动机混合动力推进系统（醇电混合动力推进系统）。基于CHG234V8MPI甲醇机的台架试验数据，在Simulink中搭建混合动力推进系统模型，并设计基于确定规则的能量管理控制策略。闭环仿真试验结果表明：在典型航行工况下，与传统柴油机推进系统相比，甲醇机推进系统具有一定的节能效果和明显的减排优势，而结合了电动机的醇电混合动力推进系统则可以显著降低燃料消耗和污染物的排放；船舶能耗降低74.07%，比油耗（brake specific fuel consumption，BSFC）降低84.73%，HC降低91.13%，CO降低91.37%，NOx降低93.79%。该研究为基于低碳燃料发动机的混合动力系统在内河船舶的绿色化改造方面提供了可行的技术方案。 |

| Abstract:A diesel-powered inland patrol vessel was selected as the research subject and converted to a methanol-electric hybrid propulsion system.Based on the bench test data of the CHG234V8MPI methanol engine，a hybrid propulsion system model was established in Simulink，and an energy management control strategy based on deterministic rules was designed.Closed-loop simulation experiments results indicate that：under typical navigation conditions，compared to traditional diesel engine propulsion systems，methanol engine propulsion systems exhibit certain energy-saving effects and significant emission reduction advantages；the methanol-electric hybrid propulsion system，which integrates an electric motor，can significantly reduce fuel consumption and pollutant emissions；it realizes 74.07% reduction in vessel energy consumption，brake specific fuel consumption（BSFC）reduction of 84.73%，HC reduction of 91.13%，CO reduction of 91.37%，and NOx reduction of 93.79%. The study provides a feasible technical solution for the green retrofit of inland waterway vessels using hybrid systems based on low-carbon fuel engines. |
