摘要
针对燃料电池船舶复合供能系统中的燃料电池功率波动问题和储能单元电池荷电状态(State of Charge, SOC)极端分化问题,依据系统拓扑结构,提出基于负载功率频率分解与模糊逻辑控制法相结合的复合供能系统控制策略设计。采用实例仿真验证该设计的优势。结果表明,该设计可有效保持燃料电池输出功率平滑,对储能单元SOC具有良好的均衡控制效果。
In view of the problems of power fluctuation of fuel cell and extreme State of Charge(SOC)polarization of energy storage unit in composite energy supply system of fuel cell ship,according to the topological structure of the system,the design of control strategy for composite energy supply system is proposed based on the combination of load power frequency distribution and fuzzy logic control method.The advantages of the design are verified with an example simulation.The results show that the design can keep the output power of fuel cell smooth effectively and is of a good balance control effect on SOC of energy storage unit.
