摘　　要：压缩空气储能技术由于其规模大、效率高、环境友好等特点受到广泛关注,其中非补燃式压缩空气储能技术成熟,在运行过程中没有碳排放产生,国内已有多座非补燃式绝热压缩空气储能电站投运、在建和在规划中。然而,目前压缩空气储能系统的设计参数尚未形成统一的标准化体系,使得压缩空气储能在系统设计和性能优化面临诸多挑战。为此,对200 MW等级的压缩空气储能系统进行中温、高温储热系统方案设计,确定了关键设备参数与系统边界条件,并对中、高温储热系统方案进行了性能以及技术经济性分析对比。结果表明:高温储热系统在性能指标上优于中温储热系统,但在投资成本上高于中温储热系统。这表明在选择大容量压缩空气储能系统的储热技术路线时,需要根据具体应用场景和经济预算综合考虑。Compressed air energy storage(CAES)technologies have garnered widespread attention due to their large scale,high efficiency,and environmental friendliness.Among them,the non-combustion compressed air energy storage technology is mature,and produces no carbon emissions during operation.There are already several adiabatic non-combustion compressed air energy storage power stations in operation,under construction,and in planning in China.However,the design parameters of the CAES system lack a unified standardization system,which poses many challenges in system design and performance optimization of CAES.To solve this problem,the design of medium-temperature and high-temperature thermal energy storage system schemes for a 200 MW class CAES system is presented,the key equipment parameters and system boundary conditions are determined.Moreover,the performance and technical economy of the medium-and high-temperature thermal energy storage system schemes is compared.The results show that,the high-temperature thermal energy storage system is superior to the medium-temperature thermal energy storage system in performance indicators,but it has a higher investment cost,indicating that when choosing the thermal energy storage technology route for large-capacity CAES systems,it is necessary to consider comprehensively based on specific application scenarios and economic budgets.
