摘要
为了分析固体氧化物燃料电池与微型燃气轮机(SOFC-MGT)联合发电系统在不同循环方式下的性能优劣,提出了一种SOFC-MGT顶层-底层联合循环结构。运用Matlab/Simulink软件分析了不同燃料流量、不同电堆温度以及不同放电电流对SOFC-MGT顶层-底层循环系统功率、效率等性能的影响,研究结果表明:燃料流量的增大可以明显地提高系统的输出功率,但系统的效率会随着燃料流量的增大而减小;电堆温度的升高有利于提高系统的输出功率;随着放电电流的增大,电堆的输出功率逐渐增大,涡轮的输出功率逐渐减小。
In order to analyze the performance of the solid oxide fuel cell and micro gas turbine(SOFC-MGT)combined power generation system under different cycle modes,the SOFC-MGT top-bottom combined cycle structure was proposed.Using Matlab/Simulink software,we analyzed the effects of different fuel flow rates,different stack temperatures,and different discharge currents on the power and efficiency of the SOFC-MGT top-bottom cycle system.The research results show that output power of the system would increase with the fuel flow rate increasing,but the efficiency of the system will decrease with the increase of the fuel flow;the output power of the system increases with the increase of the stack temperature;the output power of the stack gradually increases with the increase of the discharge current,and the output power of the turbine gradually decreases with the increase of the current.
