摘要
绿色化和智能化是地铁能源系统的重要发展方向,但当前地铁供电系统无法满足该发展的要求。能源互联网具有开放性、互联性和灵活性的特点,能够补足地铁能源系统的短板,而作为能源互联网核心设备的能源路由器将是现有地铁能源系统改造和性能提升的关键装备之一。文章基于对当前各种能源路由器应用特点的分析,提出了一种适合于地铁应用的能源路由器方案,其能实现分布式能源在地铁中的即插即用并使地铁能源系统能精确控制能源流动;介绍分析了该能源路由器的应用方式、拓扑结构和控制策略,并对其进行了样机实验。实验结果表明,该能源路由器控制灵活、响应速度快,其所在地铁能源系统的整体效率高于传统地铁能源系统的整体效率。
Green and intelligence are important development directions of subway energy system, but current subway power supply system cannot meet the requirements. Energy internet can complement the short board of subway energy system with its openness, interconnectedness and flexibility, and energy router will be one of the key equipments for subway energy system transition and performance improvement. By analyzing the characteristics of different energy routers, it proposed a design of subway energy router which could realize plug-and-play of distributed energy resources in subway and precision control of energy flow in the subway energy system. In addition, it introduced and analyzed its application scenario, topology and control strategy. Prototype test results show the flexibility and fast response of the subway energy router, and the higher overall efficiency of the subway energy system with energy routers than that of the conventional subway energy system.
