| 摘要:基于某船排放问题提出4种电动化改造方案，即全电、混合动力（两种方式，即电池满足4个或3个航次能量需求）以及电容方案。结合改造要求，分析各改造方案优劣后可知混合动力方案（3个航次）可行性最高，并讨论其系统电网结构与充电系统的可行方案。通过与传统动力系统方案对比，对其经济性与节能减排优势进行分析，得出节能减排优势较大，但经济性较低，提出平均分摊法电池租赁模式提高其经济性。 |

| Abstract:Based on the emission problem of a ship，four electrification transformation schemes are proposed，which are all electric，hybrid（two modes，namely，the battery can meet the energy demand of four or three voyages）and capacitor schemes.According to the transformation requirements，after analyzing the advantages and disadvantages of each transformation scheme，it can be seen that the hybrid power scheme（3 voyages）has the highest feasibility，and the feasible scheme of its system grid structure and charging system is discussed.By comparing with the traditional power system scheme，its economy and capability of energy conservation and emission reduction are analyzed.It shows that the new system has obvious advantages in energy conservation and emission reduction，but has poor economy.The average sharing battery leasing mode is proposed to improve its economy. |
