摘要
在定燃料输入流量和定燃料利用率两种典型控制方式下,建立了固体氧化物燃料电池(SOFC)发电系统模型。研究了两种控制方式下的固体氧化物燃料电池堆的稳态特性,采用定燃料流量控制方式时考虑了燃料流量对SOFC稳态特性的影响。针对出现负荷改变和故障的情况,分别在两种典型控制模式下对SOFC发电系统进行了仿真,通过对仿真结果的比较,给出了两种控制方式的适用范围。
The Solid Oxide Fuel Cell generation system model is established ,which operated in constant fuel flow and constant fuel utilization. The steady-state （V-I and P-I） characteristics of the SOFC stack model has been studied, and the effect of fuel flow on the characteristics of SOFC steady-state in constant fuel flow mode has been obtained. Then SOFC stack operated in two different typical modes are applied in the simulation of SOFC-bascd distributed generation system aiming at changing load and fault condition. By comparing the simulation results, the applicable application sphere of two operation mode are given.
