摘要:
针对废弃洞穴再利用、压缩空气储能系统储气空间成本高等问题，该文提出了一种以废弃洞穴为储气空间复合压缩空气储能系统，通过建立系统的热力学模型，研究了典型工况下系统关键参数和热力学性能的演化规律，揭示了不同运行特征下系统的储能密度和效率变化趋势。研究结果表明：随着双罐的循环次数的增加，系统中空气质量流量和单次循环水泵耗功都增大；储气洞穴热力参数在储能时存在8次波动，波动的次数由双罐的循环次数决定；在释能阶段，储气洞穴的温度变化存在两个阶段：温度骤降阶段和骤降变缓阶段，形成是由于空气膨胀和空气与洞穴壁换热的双重作用；储能密度在多变压缩机压比为3.6时达到最大值为2.47 kW?h/m3，而系统效率在压比为3.5时达到最佳值为76.4%；储气洞穴容积随压缩机压比一直增大，这会导致储能系统经济性降低；应综合考虑储能密度、系统效率和储气洞穴容积来设置系统设备参数，多变压缩机压比参数选取应在3.5~3.6之间。
Abstract:
To address the problems of reuse of abandoned caves and high cost of compressed air storage space in compressed air energy storage system, this paper proposes a composite compressed air energy storage system with abandoned caves as the storage space. By establishing the thermodynamic model of the system, the evolution law of key parameters and thermodynamic performance of the system under typical working conditions is studied, and the trends of energy storage density and system efficiency changes of the system under different operating characteristics are revealed. The research results show that: with the increase of the cycle number of double tanks, the air mass flow rate and the work consumption of single cycle pump in the system increase. There are 8 fluctuations of air flow rate in the storage chamber, and the number of fluctuations is determined by the cycle number of double tanks. In the energy release stage, there are two stages of temperature change in the storage cavern: the temperature plunge stage and the plunge slow stage, which are formed due to the dual action of air expansion and heat exchange between air and cavern wall. The energy storage density reaches the maximum value of 2.47 kW?h/m3 when the pressure ratio of multivariable compressor is 3.6, and the system efficiency reaches the best value of 76.4% when the pressure ratio is 3.5. The volume of gas storage cavern increases with the pressure ratio of compressor, which leads to the reduction of the economy of energy storage system. The system equipment parameters should be set by considering the energy storage density, system efficiency and gas storage cavern volume, and the multivariable. The compressor pressure ratio parameter should be selected between 3.5~3.6.
