一、概述 光伏预制舱是一种集成式光伏发电设备，其核心功能是将光伏电站中的关键电气设备（如逆变器、汇流 箱、变压器、储能变流器PCS、电池簇等）、辅助系统（通风、散热、消防、监控等）及内部布线，在 工厂内完成集成、调试与检测，再运输至项目现场进行简单拼接和接线，即可快速投入运行的标准化设 备单元，其具有占地面积小、施工周期短、环境适应性好、耐冲击、耐腐蚀、耐高/低温等优势。 按核心集成设备不同，光伏预制舱可以分为光伏逆变器预制舱、光储一体化预制舱、升压预制舱、汇流 预制舱、综合控制预制舱等类型，其中，光伏逆变器预制舱主要应用于大型地面光伏电站（集中式逆变 器舱）、工商业分布式电站（组串式逆变器舱）等场景；光储一体化预制舱主要应用于需峰谷套利、备 用电源的光伏电站（如工商业光储、微电网项目）等场景；升压预制舱主要应用于大型地面光伏电站 （需远距离输送电能）、并网电压等级较高的项目等场景；汇流预制舱主要应用于组件布局分散、汇流 需求高的大型电站等场景；综合控制预制舱主要应用于大型电站的中央控制中心或需集中管理的分布式 电站集群等场景。 光伏预制舱分类 内容概要：在光伏电站向"标准化、模块化、快速化"建设转型的背景下 ...
