【摘要】 先进绝热压缩空气储能（advanced adiabatic compressed air energy storage system,AA-CAES）仿真建模及分析是其工程实践的基础。然而，目前模型一般基于理想工况建立，分析结果与实际工况相偏差较大，无法指导工程应用。为此，在传统热力学模型基础上，考虑了空气流动阻力损失和能量转换设备损耗等因素，建立了面向工程应用的AA-CAES模型并以200MW盐穴AA-CAES系统为例进行了分析。同时，对系统效率分析方法进行改进并对其进行了先进(火用)分析。结果表明，空气管道(火用)损失占总(火用)损失比例接近7%，能量转换设备损耗导致电-电效率比轴功效率低5%，二者对系统性能影响较大，在进行工程设计时不可以忽略。系统各部件可避免(火用)损失占比均较大，表明系统具有较大的性能提升潜力。各部件(火用)损失为其内部(火用)损失，与其他部件是否工作在最佳状态关系不大。更多还原

【Abstract】 The simulation modeling and analysis of the advanced adiabatic compressed air energy storage system(AACAES) is the foundation of its practice engineering. However,current models are generally based on ideal conditions, leading to a significant deviation from the practice engineering, which cannot guide the engineering applications. Therefore, based on the traditional thermodynamic models and considering the air flow and energy conversion losses, an AA-CAES model for engineering applications was established and taking the 200 MW salt cavern AA-CAES system as an example. Meanwhile, the system efficiency analysis method was improved and advanced exergy analysis was conducted on it. The results show that the exergy destruction of air pipes accounts for nearly 7% of the total exergy destruction, and the loss of energy conversion equipment leads to a 5% decrease in energy storage efficiency compared to shaft power efficiency. Both have significant impact on system performance and cannot be ignored in engineering design. The proportion of avoidable exergy destruction in each component of the system is relatively high,indicating that the system has great potential for performance improvement. The exergy destruction of each component is mainly endogenous, which is not closely related to whether other components are working in their optimal state.更多还原
