【摘要】：外界大气环境中存在的广泛灰尘,对光伏组件发电系统在实际运行过程有很大影响。沉积在光伏组件玻璃表面上的灰尘会降低透光率,导致光伏组件接受阳光辐照度低于清洁时候接受阳光辐照度。随着沉积浓度越大透过率就会越低,光伏组件接受阳光收辐照度越低,从而严重的降低了光伏组件发电效率。减少或者清除光伏组件玻璃表面上沉积的灰尘,保持光伏组件表面清洁是很有必要的工作。本文以重庆理工大学光伏新能源应用技术与设备研究所前期研究结果为基础,对原有的单块光伏组件除尘装置样机优化和改进,设计、制造及验证了一款针对于有两块光伏组件组成光伏阵列的自动除尘装置。首先,对光伏组件玻璃表面灰尘来源,吸附的原因进行研究分析,确定了清除灰尘的方式。根据光伏组件安装方式及除尘目的要求,确定设计总体方案。在原有除尘装置样机基础上,通过SolidWorksmotion模拟仿真,设计了一款通过螺旋滚刷清除光伏组件玻璃表面灰尘的机械装置。通过实验方法确定除尘装置滚刷刷毛与光伏组件玻璃表面合适的接触量,通过研究分析了滚刷结构、滚刷类型、机构参数及刷毛材料。根据除尘动作及控制要求,设计了自动控制部分、检测部分、远程控制部分,通过比较分析,最终选择了单片机作为自动控制器,同时对单片机、传感器等电气元件进行了选型。最后通过试验来验证除尘装置除尘效果,数据分析结果表明此样机清理灰尘效果显著,运行稳定,具有较好的实用价值。
[Abstract]:The extensive dust in the outside atmospheric environment has a great influence on the actual operation of photovoltaic module power generation system. The dust deposited on the photovoltaic module glass surface will reduce the transmittance. The higher the deposition concentration, the lower the transmittance, and the lower the photovoltaic module is. This seriously reduces the efficiency of photovoltaic module power generation. Reduce or remove dust deposited on the surface of photovoltaic module glass. It is necessary to keep the photovoltaic module surface clean. This paper is based on the previous research results of the Institute of photovoltaic New Energy Application Technology and equipment of Chongqing University of Technology. For the original single photovoltaic module dust removal device prototype optimization and improvement, design, manufacture and verification of a photovoltaic module for the photovoltaic array for the automatic dust removal device. First of all. The source of dust on the glass surface of photovoltaic module and the reason of adsorption were studied and analyzed, and the way of dust removal was determined, according to the installation mode of photovoltaic module and the requirements of dust removal purpose. The overall design scheme is determined. Based on the prototype of the original dedusting device, the simulation is carried out by SolidWorksmotion. A mechanical device was designed to remove the dust on the glass surface of photovoltaic module by spiral roller brush, and the proper contact amount between the brush hair and the glass surface of photovoltaic module was determined by the experimental method. According to the dust removal action and control requirements, the automatic control part, the detection part and the remote control part are designed. Finally, the singlechip is chosen as the automatic controller, and the electrical components such as single chip microcomputer and sensor are selected. Finally, the dust removal effect of the dust removal device is verified by experiments. The result of data analysis shows that the dust cleaning effect of this prototype is remarkable, the operation is stable, and it has good practical value.
