为提升储能式有轨电车项目的运用管理水平，优化后续新建项目设计，降低项目全寿命周期成本，本文以广州海珠试验段、广州黄埔1号线及三亚有轨电车项目车辆储能系统为研究对象，结合各自线路供电系统的设计特点，对三种不同系统所采用的关键技术原理、能量存储及消耗参数、运营维护重难点、使用寿命及成本等方面进行了对比分析。其中超级电容和电池电容储能系统在设备运用可靠性方面具有一定的优势；从可维护性方面，三种系统制式均存在维护难点；电池电容储能系统的衰减程度较大。综合来看，在提升单一制式储能系统的续航能力和混合供电系统运用可靠性的基础上，适当简化供电系统，开展集约型的设计将是今后储能式有轨电车工程的发展方向。

In order to improve the operation and management level of the energy storage tram projects, optimize the design of subsequent new projects and reduce the life cycle cost, this paper takes the vehicle energy storage system of Guangzhou Haizhu test section, Guangzhou Huangpu line 1 and Sanya tram project as the research object, combines with the design characteristics of their power supply system, analyzes the key technical principles, energy storage and consumption parameters, operation and maintenance difficulties, service life and costs. Among them, super capacitor system and battery capacitor system have certain advantages in equipment reliability; in terms of maintainability, all three systems have maintenance difficulties; battery capacitor systems have a higher degree of attenuation. Overall, improving the capacity of single energy storage system and the reliability of hybrid power supply system, simplifying the power supply system and carrying out intensive design will be the development direction of energy storage tram project in the future.
