摘要

为定量评估空气湿度和环境温度对大容量压缩空气储能系统运行特性的影响,对空气物性进行高精建模,搭建大容量压缩空气储能工程的全工艺流程仿真系统。研究表明,将空气视为理想气体可导致系统设计容量偏小、热功供给不足,且这种缺陷在高温高压区间越发明显。空气湿度和环境温度对压缩系统的运行特性影响较大,当空气湿度增加、环境温度升高时,压缩系统的注气能力降低,为保证储气室压力,压缩系统须开大变频且增加注气时长,导致功耗等关键参数的改变。无论对于中温和高温压缩策略,水分析出量最大均发生在首级和第2级压缩流程,且随湿度的增大和环境温度的升高,各级水分析出量均增加且位置前移,运行中应格外关注。

Abstract

This study aimed to investigate how the atmospheric humidity and environment temperature of air affect the performance of a 300 MW compressed air energy storage power plant. A comprehensive mathematical model accounting for high-precision air physical properties was developed. The results show that assuming air behave as an ideal gas results in a smaller design capacity than in reality, leading to insufficient heat and power supply, particularly at high pressure and temperature. Additionally, the influence of the atmospheric humidity and environment temperature on the operational characteristics of compressors were studied. An increase in atmospheric humidity and environment temperature reduces the output of the compression system, requiring a larger opening of the frequency converter and a longer charging time to maintain the design pressure of the air reservoir. Finally, water condensation is most intense at Stages 1 and 2 for both intermediate and high-temperature scenarios. As the atmospheric humidity and temperature increase, more water condenses for every stage and the position where condensation happens moves ahead. Operators must address this issue by monitoring the position of condensation and taking appropriate measures.
