摘要
基于一艘超级电容为动力来源的全电力推进船舶,加入燃料电池后组成混合储能动力船舶,使得不同的储能元件发挥其优势,平衡复杂的负载功率波动,延长船舶续航里程,优化能量的使用效率。超级电容和燃料电池分别以双向半桥DC-DC变换器和Boost变换器作为媒介,与600V直流母线连接,通过双闭环控制策略对总线电压和各储能元件电流进行控制;同时,采用一种新型的能量管理方法,以超级电容荷电状态为基础,使得能量分配保持动态平衡。Matlab/Simulink仿真结果表明,该方法有效地利用了各储能元件的优势,发挥了超级电容平复负载波动的作用,超级电容作为储能元件的能量也得到充分利用。
This paper consider a full electric propulsion ship using pure supercapacitor as the powertrain,combined with fuel cell consisting of a hybrid source storage.The aim is to let each part of the storages make full use of its strengths,balance power fluctuation,extend mileage,and optimize the energy utilization rate.The supercapacitor and the fuel cell are connected to a 600 VDC bus with a half-bridge DC-DC converter and a boost converter respectively.The bus voltage and the current of each energy storage are controlled with a double closed-loop control strategy.Meanwhile,an energy management method,based on the state of charge(SOC)of supercapacitor,dynamic balance of energy distribution is maintained.Results of Matlab/Simulink simulation show that the method can make full advantage of each energy storage,keep the load fluctuation flat.The supercapacitor is also used as energy storage.
