南昌市某公交站台的光伏智能化改造设计

Photovoltaic Intelligent Transformation Design of a Bus Station in Nanchang City

为方便市民出行、提升城市形象,对南昌市某传统公交站台进行光伏智能化的改造设计,通过增加电子显示屏和手机充电系统,满足不同人群的需求。首先介绍了系统的结构、工作原理,选取了所需的光伏组件、逆变器、防雷接地设备;然后对系统的改造成本、经济收益、环境效益等进行分析计算;最后,对光伏智能化改造的发展提出展望。经改造设计,选用5块400 W的单晶硅组件串联安装在车站顶棚,通过3 kW的并网逆变器、双向电度表与公共电网连接,采用“自发自用、余电上网”模式,在满足自身用电的同时,每年还有718 kW·h电结余,首年可获得1207元的收益。初步探讨了光伏智能化改造的可行性,为“双碳”目标的实现提供支持。

In order to facilitate citizens'travel and improve the image of the city,the photovoltaic intelligent transformation design of a traditional bus station in Nanchang city was carried out,and the electronic display screen and mobile phone charging system were added to meet the needs of different people.Firstly,the structure and working principle of the system were introduced,and the required photovoltaic modules,inverters and lightning protection grounding equipment were selected.Then the cost,economic benefits and environmental benefits of the system were analyzed and calculated.Finally,the development prospect of photovoltaic intelligent transformation was put forward.Through the transformation design,five pieces of 400 W monocrystal silicon components were installed in series on the roof of the station,connected to the public power grid through a 3 kW grid connected inverter and two-way electricity meter,and the mode of"self-use and surplus electricity online"was adopted.In addition to meeting their own electricity consumption,there was a power balance of 718 kW·h every year,and the first year could obtain a profit of 1207 yuan.The feasibility of intelligent transformation of photovoltaic was preliminarily discussed to provide support for the realization of the"double carbon"goal.
