【摘要】：固体氧化物燃料电池(Solid Oxide Fuel Cell,SOFC)与微型燃气轮机(Micro Gas Turbine,MGT)相结合的混合动力系统是近年来开发的一种很有发展前景的船舶动力系统,可实现高效(效率高达80%)和低排(污染废气排放几乎为零)的目标,但其作为一种船舶动力系统,控制关键是保持SOFC化学反应所产生动力与MGT旋转所产生动力的平衡。在建立系统模型的基础上,提出混合动力系统的控制方案。为获得最大的效率,对SOFC的堆栈温度、燃料流量、燃料利用率和对应功率等关键参数进行研究。同时,提出SOFC与MGT两种动力系统之间动力分配的控制方法。结果表明:该控制系统能有效控制该混合动力系统,使其独立承担适当的负荷和适应负荷的变动。
[Abstract]:The hybrid power system based on solid oxide fuel cell (solid oxide fuel cell) and micro gas turbine (Micro Gas Turbineine MGT) is a promising marine power system in recent years. It can achieve the goals of high efficiency (efficiency up to 80%) and low emission (pollution emission is almost zero), but as a ship power system, the key to control is to keep the balance between the power generated by SOFC chemical reaction and the power produced by MGT rotation. Based on the system model, the control scheme of hybrid power system is proposed. In order to obtain the maximum efficiency, the key parameters such as stack temperature, fuel flow rate, fuel utilization ratio and corresponding power of SOFC are studied. At the same time, the control method of dynamic distribution between SOFC and MGT is proposed. The results show that the control system can effectively control the hybrid power system and make it bear the appropriate load and adaptive load independently.
