摘　　要：可再生能源的间歇性和波动性等特性给电网调度带来了挑战。液态空气储能系统不仅规模大、储能时间长,而且具有储能密度高、不受地理环境限制等特性,是解决这一问题的有效技术措施之一。首先,介绍了5种经典的空气液化循环技术的原理,分析了不同液化技术在空气液化方面的特点。然后,分析了2种空气液化循环的改进技术,比较了不同的空气液化技术在液化能力、经济性等方面的优势与不足。综述认为,如果综合考虑液化率、经济成本和安全性,应尽量采用Linde-Hampson循环和Claude循环。最后,分析了现有的空气液化技术在液化率、冷量缺口等方面存在的问题,探讨了液态空气储能系统空气液化技术的未来发展趋势。Characteristics such as intermittency and volatility of renewable energy pose challenges to grid scheduling.Liquid air energy storage system is one of the effective technical measures to solve this problem,not only in terms of large scale and long storage time,but also in terms of high energy storage density and not limited by geographical environment.Firstly,the principles of five classical air liquefaction cycle technologies were introduced,and the characteristics of different systems in terms of air liquefaction were analyzed.Secondly,the improved technologies of two air liquefaction cycles were analyzed,and comparisons were conducted on the advantages and shortcomings of different air liquefaction technologies in terms of liquefaction capacity and economy.It is concluded that Linde-Hampson cycle and Claude cycle should be adopted based on the comprehensive consideration of liquefaction rate,economic cost and safety.Finally,the problems of existing air liquefaction technologies in terms of liquefaction rate and cooling capacity gap have been analyzed,and the future development trend of air liquefaction technologies for liquid air energy storage systems has been discussed.
