| 目的 降低船舶污染排放，延长电池使用寿命，改善变工况条件下储能系统的动力性。方法 电池系统采用基于经验模态分解及模糊控制的双层管理策略，以磷酸铁锂电池组为主动力源来承担平缓功率，超级电容组为辅动力源来承担高频功率，引入样本熵对功率信号进行评估。结果 以某船舶工况进行仿真，相较于单一经验模态策略，引入模糊修正策略后的磷酸铁锂电池组放电深度由6.55%~94.35%变为14.56%~57.15%；超级电容组的放电深度由14.83%~52.11%变为12.7%~79.38%；磷酸铁锂电池组功率信号样本熵值由0.0182降为0.0177。结论 变工况条件下，上述控制策略可降低单工况下柴油机平均燃油消耗，减少储能端电池受到暂态功率的冲击，延缓电池老化速度，加长电池使用寿命，提升船舶储能系统的可靠性及环保性。 |

| This paper aims to reduce pollution emissions from ships, extend battery life, and improve the dynamics of energy storage systems under variable operating conditions. The battery system adopts a two-layer management strategy based on empirical mode decomposition and fuzzy control. The lithium iron phosphate battery pack is used as the main power source to bear the smooth power, and the super capacitor pack is used as the auxiliary power source to take the high frequency power. The sample entropy is introduced to the power signal to evaluate. Compared with a single empirical mode strategy, the discharge depth of the lithium iron phosphate battery pack after the fuzzy correction strategy is changed from 6.55% ~ 94.35% to 14.56% ~ 57.15%; the super capacitor pack discharge depth from 14.83% ~ 52.11% to 12.7% ~ 79.38%; the entropy value of the power signal sample of the lithium iron phosphate battery pack decreases from 0.0182 to 0.0177.Under variable operating conditions, the above control strategy can reduce the average fuel consumption of the diesel engine under single operating conditions, reduce the impact of transient power on the storage battery, delay the aging rate of the battery, extend the battery life, and improve the reliability of the marine energy storage system and environmental protection. |
