The invention discloses a ship fuel cell power management method and management system, and the method comprises the steps: S1, determining a charging mode if a shore power supply is connected, and executing S5; otherwise, determining a navigation mode and executing S2; s2, analyzing the electric quantity of the storage battery unit and the electrical load of the ship; when the electric quantity of the storage battery unit is high, executing S5; s3 is executed when the electric quantity is medium; executing S4 when the electric quantity is low; s3, when the electrical load of the ship is in the N-gear load interval, controlling the output power of the fuel cell to be in the N-gear power interval of the same grade; wherein N is a natural number greater than or equal to three; s4, when the electrical load of the ship is in the N-gear load interval, controlling the output power of the fuel cell to be in the N + 1-gear power interval of the higher gear; and S5, stopping the operation of the fuel cell. The system is used for implementation of the method. Start-stop and power change times of the fuel cell can be effectively reduced, loss is reduced, and power generation efficiency is improved.
本发明公开了一种船舶燃料电池功率管理方法及管理系统,方法包括S1、若连接岸电电源、则判定为充电模式并执行S5;否则判定为航行模式并执行S2;S2、分析蓄电池单元的电量和船舶用电负荷;当蓄电池单元的电量处于高电量时执行S5;处于中电量时执行S3;处于低电量时执行S4;S3、船舶用电负荷处于N档负荷区间时,将燃料电池的输出功率控制在相同档次的N档功率区间内;其中N为≥三的自然数;S4、船舶用电负荷处于N档负荷区间内时,将燃料电池的输出功率控制在高一档次的N+1档功率区间内;S5、燃料电池停止运行。系统用于方法的实施。本发明可有效减少燃料电池起停和功率变化次数,降低损耗,提高发电效率。
