摘要:
为了评估有轨电车车载光伏系统接入24 V直流母线方案的可行性及其经济性，以世界首列氢燃料电池混合动力100%低地板有轨电车为研究对象，设计了车载光伏发电系统，描述了该系统在有轨电车上的安装位置及安装尺寸。采用标准小时数法对有轨电车寿命周期内安装了透光组件后车载光伏发电系统的发电量进行了预测。详细介绍了有轨电车车载光伏发电系统接入24 V直流母线方案。研制了车载光伏样车，其电气系统由车载光伏发电系统、数据采集系统及辅助供电及储能装置等组成，并给出了车载光伏发电系统样车的电气拓扑图。构建了有轨电车车载光伏发电系统接入24 V直流母线方案的经济性模型，基于理论计算与样车测试开展了经济性分析。结果表明：3节编组有轨电车车顶铺设的铜铟镓硒薄膜电池发电量为19.11 kWh/d，3~4年即可收回成本。有轨电车车载光伏发电系统具有良好的经济性能。
Abstracts:
To evaluate the feasibility and economy of tram on board PV (photovoltaic) system accessing 24 V DC bus scheme, taking the world first hydrogen fuel cell hybrid power 100% low floor tram as research object, on board PV power generation system (hereafter OPVGS for short) is designed and the installation position and dimensions of the system on trams are described. The power generation amount of the on board PV system after installing translucent modules within tram lifespan is predicted by standard hours method. The scheme of tram OPVGS accessing 24 V DC bus is introduced in detail. The prototype vehicle with on board PV is developed, the electric system of which is composed of OPVGS, data acquisition system and auxiliary power supply and storage equipment, and the electrical topology diagram of the prototype vehicle with OPVGS is given. An economy analysis model of the tram OPVGS accessing 24 V DC bus scheme is constructed, and economy analysis is carried out based on theoretical calculation and prototype vehicle test. Results show that power generation of copper indium gallium selenium thin film cell laid on the roof of 3 car formation tram is 19.11 kWh/d, and the cost can be recovered in 3 to 4 years. The tram OPVGS proves to have good economic feasibility.
