摘　　要：新型储能是推动能源转型和构建新型“源网荷储”电力系统的重要基础装备,已成为我国战略性新兴产业。近年来,在国家政策和技术研发创新的双轮驱动下,我国新型储能规模化发展趋势逐渐呈现。重力储能因其高效、环境友好、稳定性高、具有大规模储能能力而作为一种新型储能技术受到无数专家和学者的关注。与此同时,地下资源的枯竭使部分矿井面临废弃。本文回顾了国内外竖井式重力储能系统的发展状况,说明了废弃矿井在重力储能技术的发展中可以作为一种再利用资源为人们所用,构建了基于直线电机的竖井式重力储能系统的数学模型,着重介绍了直线电机在废弃矿井这一特殊应用场景中的应用价值,使用滑轨代替了旋转电机运行过程中的缆绳,有助于提高竖井式重力储能系统的稳定性,分析了竖井式重力储能系统可能存在的几种构型,对比了不同直线电机结构方面的优缺点,阐述了直线电机不同运行状况下的控制技术以及控制目标,概括了现有的多电机控制技术,展望了未来直线电机在竖井式重力储能系统中的应用。Innovative energy storage promotes energy transformation and establishes a new"source network storage"power system,serving as an essential infrastructure and emerging as a key strategic industry in China.In recent years,driven by national policy,technological research,and innovative development,the trend of new energy storage scale development in China has gradually emerged.Gravity energy storage is recognized as a novel strategy for its high efficiency,environmental sustainability,exceptional stability,and large-scale energy storage capacity,as confirmed by countless experts and researchers.Simultaneously,the depletion of underground resources leads to the abandonment of certain mines.This paper reviews the development of shaft-type gravity energy storage systems,explains the potential of reusing abandoned mines as a resource in the development of gravity energy storage technology,constructs a mathematical model of shaft-type gravity energy storage system based on linear motors,and emphasizes the value of the linear motors in the special application scenario of abandoned mines,where slide rails replace cables in the operation of rotating motors,effectively addressing the challenges posed by abandoned mines.The use of slide rails instead of cables during rotating motors enhances the stability of the shaft-type gravity energy storage system,analyses the possible configurations of the system,compares the advantages and disadvantages of the different linear motors,elucidates the control technology and the objectives of the linear motors under diverse operating conditions,summarizes the existing multi-motor control technology,and anticipates future applications of linear motors in the shaft-type gravity energy storage system.
