摘　　要：燃料电池船混合动力系统采用燃料电池作为主电源,蓄电池作为能量储存单元。为了最小化燃料电池的氢气消耗,针对燃料电池混合动力船提出了一种燃料消耗优化能量管理策略,为保证蓄电池工作在优化范围内,引入蓄电池的充电保持策略。基于MATLAB/SIMULINK仿真环境建立燃料电池混合动力系统的仿真模型。根据典型的船舶行驶工况对所给出的优化能量管理策略进行了仿真验证,并与功率跟踪能量管理策略进行对比。仿真结果表明,所提出的优化理论能提高燃料经济性,同时使蓄电池SOC保持在合理范围内。In this study, the hybrid power system of the fuel cell ship combining fuel cell, as the main power source, and battery, as the energy storage unit is developed. A fuel consumption optimal energy management strategy was proposed for the fuel cell hybrid ship, aiming to minimize the hydrogen consumption of the fuel cell stack. For ensuring the battery working at the optimum region, a charge-sustaining strategy for the battery was introduced. The simulation model of the fuel cell hybrid power system was established in the MATLAB/SIMULINK simulation environment. The optimal energy management strategy was verified by simulation according to the typical drive cycle of ship compared to power following energy management strategy. The simulation results show that the proposed optimization can improve fuel economy while the state of charge （SOC） of the battery is maintained at reasonable range.
