摘要
光伏电池是光伏发电技术的关键设备,承担着光电转换任务,需要工作在最大功率点才能获得最佳工作状态。而现有机器人会随着光伏组件的老化,影响最大功率点的跟踪效果,无法充分应用太阳能,故提出光伏发电系统的最大功率点跟踪智能机器人设计研究。最大功率点跟踪智能机器人硬件设计为传感器选取单元、最大功率点跟踪单元及其运动控制单元;软件模块为跟踪智能机器人模型构建模块、最大功率点跟踪模块及其机器人滑模轨迹跟踪控制模块。通过上述硬件单元与软件模块的设计,实现了光伏发电系统的最大功率点跟踪智能机器人的运行。实验数据显示:应用智能机器人后,最大功率点跟踪匹配因数更大,跟踪轨迹与最大功率点固定变化轨迹差距更小,充分证实了智能机器人最大功率点跟踪效果较佳。
Photovoltaic cell is the key equipment of photovoltaic power generation technology,which undertakes the task of photoelectric conversion.It needs to work at the maximum power point to obtain the best working state.The existing robots will affect the tracking effect of maximum power point with the aging of photovoltaic modules,and can not make full use of solar energy.Therefore,the design and research of intelligent robot for maximum power point tracking of photovoltaic power generation system is proposed.The hardware design of maximum power point tracking intelligent robot is sensor selection unit,maximum power point tracking unit and its motion control unit.The software modules are the model building module of tracking intelligent robot,the maximum power point tracking module and its robot sliding mode trajectory tracking control module.Through the design of the above hardware units and software modules,the operation of the maximum power point tracking intelligent robot of the photovoltaic power generation system is realized.The experimental data show that after the application of intelligent robot,the maximum power point tracking matching factor is larger,and the gap between the tracking track and the fixed change track of maximum power point is smaller,which fully proves that the maximum power point tracking effect of intelligent robot is better.
