固体氧化物燃料电池与微型燃气轮机联合发电建模仿真研究

摘要

A solid oxide fuel cell and micro gas turbine combined power generation system was designed and considered the working performance through modeling and simulation.The model is established by modularization modelling method based on Matlab/Simulink.Then all submodulars are connected by topological structure and make up the SOFCMGT combined power generation system.After simulation,the result shows that the model can meet the requirements of the simulation precision and the system can operate with high efficiency.At off-design condition,especially when the high back pressure exists,the system can't be stably operating.In order to ensure it running well,water-processing must be loaded.%设计一种固体氧化物燃料电池与微型燃气轮机的联合发电系统,并对其进行建模仿真及性能研究.基于Matlab/Simulink仿真软件,采用模块化建模方法,再以拓扑结构连接各个子系统模型,搭建SOFC-MGT联合发电系统模型.仿真结果表明:模型满足仿真要求,系统具有较高的发电效率.在变工况,尤其是高背压条件下,该系统不能稳定工作,必须附加水处理系统才能保证该系统良好运行.
