中文摘要 |
固体氧化物燃料电池(Solid Oxide Fuel Cell, SOFC)系统的建模方式较多,而基于机理模型的故障诊断是能够通过系统的动态趋势辨别故障的有效手段之一,但该方法对机理模型的准确性有要求。此外,不同的燃料供给系统采用的系统结构也是有差异的,进而导致在相同故障下SOFC系统的动态响应也是不同的。因此,本文基于两种燃料供应方式,提出了分别以纯氢气和天然气作为燃料的SOFC 系统结构,并基于原有机理知识进行Matlab/Simulink 系统建模。经与真实SOFC系统实验对比,搭建的系统模型能够有效模拟系统在无故障状态下的动态变化;另外,在无故障模型的基础上,分别加入两类常见故障,其一为风机故障,其二为燃料供应管路泄露。最后通过仿真分析,明确了所搭建模型的合理性,且发现了两种燃料供应对SOFC系统热响应特性是不同的,对SOFC系统故障的检测和设备选型具有重要意义。 |
英文摘要 |
There are many modeling methods for Solid Oxide Fuel Cell (SOFC) systems. One of the fault diagnosis methods is based on accurate system modeling. In addition, different fuel supply systems adopt different system structures, which lead to different dynamic response of SOFC system under the same fault condition. Therefore, based on two kinds of fuel supply modes, this paper proposes the SOFC system structure using pure hydrogen and natural gas as fuel, respectively. Based on the original knowledge, the system model is built by MATLAB/Simulink. Compared with the real SOFC system experiment, the system model can simulate effectively the system dynamic under the fault-free condition. Moreover, fuel supply manifold leakage fault and blower fault are added to fault-free model respectively. Finally, through simulation analysis, the rationality of the model is clarified. It is found that the thermal response characteristics of two kinds of fuel supplied SOFC system are different, which has important significance for fault detection and type selection of SOFC system. |
