Study on energy saving of hybrid power ships based on BDS

提出一种基于北斗卫星导航系统(BDS)的油电混合动力推进系统,柴油机和电动机采取PTH驱动方式,采用燃油和电能混合提供推进动力,可以依据BDS导航的航行区域以及航行速度选择不同动力源输出.经过燃油经济性和效益分析,与传统推进系统相比,应用基于BDS的混合动力推进系统,公务船运营成本降低26%,增加的初始建造投资成本3年内可以收回;金枪鱼延绳钓船综合节油15%~20%,通过节油方式可在4年内收回初始建造投资成本.基于BDS的混合动力系统可以增加推进冗余度,提高船舶安全性,具有良好的节能减排和节约运营成本的效果.

This paper proposes a hybrid electric propulsion system based on BDS.The two main power sources of the diesel engine and the electric motor adopt PTH driving mode.The fuel and electric energy are used to provide propulsion power.Different navigation areas and speed can be selected according to BDS Power source output.After fuel economy and benefit analysis,compared with the traditional propulsion system,the application of BDS-based hybrid propulsion system reduces the operating cost of official ships by 26%,and the increased initial construction investment cost of tana business ship can be recovered within 3 years;Comprehensive fuel saving of 15%to 20%,the initial construction investment cost can be recovered within 4 years through the fuel saving method.The hybrid system based on BDS can increase propulsion redundancy,improve ship safety,and has good effects of energy saving and emission reduction and saving operating costs.
