Design of water cycle photovoltaic power generation system based on NB-IoT

针对光伏电池工作时温度升高导致发电效率下降,提出一种基于窄带物联网(NB-IoT)云平台的水循环光伏发电系统。将采集的太阳能电池板环境数据通过NB-IoT专用网络上传到云平台,云端控制系统根据得到的数据对光伏电池组进行水循环降温,使光伏电池组始终处于最佳工作状态;同时,系统产生的“垃圾电”可存储于蓄电池组,在用电高峰期补充主电网供电不足或用于热水加热。实验结果表明:使用NB-IoT水循环发电系统的太阳能电池板温度下降约19.3℃,发电效率提升8.2%左右。

A water cycle photovoltaic power generation system based on narrow band Internet of Things(NB-IoT)cloud platform is proposed to solve the problem that the temperature of photovoltaic cells increases and the power generation efficiency decreases.The system uploads the collected environmental data to the cloud platform through the NB-IoT special network, and the cloud control system conducts water circulation cooling for the photovoltaic battery group according to the obtained data, so that the photovoltaic battery group is always in the best working state.The“garbage electricity”generated by the system can be stored in the battery group, which can supplement the insufficient power supply of the main grid or be used for hot water heating during the peak power consumption.The experimental results show that the solar panel temperature of the NB-IoT water cycle power generation system decreases by about 19.3 ℃,and the power generation efficiency increases by about 8.2 %.
