| 摘 要： | 数值模拟是固体氧化物燃料电池(SOFC)-燃气轮机(GT)混合发电技术发展的重要手段。基于自主开发的SOFC-GT混合发电系统多层次模型库,与西门子-西屋公司的示范系统额定工况试验数据对比,本模型的稳态精度优于高级能量系统分析工具(APSAT),并可用于温度、气体组分、电池极化等参数分布和动态特性分析,对于系统的稳态性能优化与负荷跟随策略具有重要意义。

| Abstract: | Numeric simulation is important for the development of solid oxide fuel cell(SOFC)-gas turbine(GT) hybrid generation technology.Based on our independently developed multi-level model library of SOFC-GT system,validated by the experimental data of Siemens-Westinghouse demonstration system in rated condition,the model in this paper predicts more accurately than the advanced energy analysis tool(APSAT) does.Furthermore,the model in this paper is also available for analysis of parameter distributions and transi... |
