摘要
以光伏系统功率提升为目标,设计了一种基于双模式切换的光伏追光双轴控制方法。利用机器视觉技术,在光照条件较为理想时根据测量装置所获取的阴影信息进行光伏面板的俯仰轴与方位轴调节;在光照条件不佳时则切换为视日运动轨迹跟踪模式,确保日照条件下太阳光始终以垂直方式入射至光伏面板。实验结果表明,采用双模式切换的追光控制策略能够获得更佳的太阳光入射角度与辐照强度,显著提升光伏系统的发电效率。
With the objective of enhancing the power output of photovoltaic systems,a dual-axis photovoltaic tracking control method based on dual-mode switching is designed.By utilizing machine vision technology,adjustments to the pitch and azimuth axes of the photovoltaic panels are made according to the shadow information obtained from measuring devices when lighting conditions are favorable.Under unfavorable lighting conditions,the system switches to the solar trajectory tracking mode to ensure that sunlight always impinges perpendicularly on the photovoltaic panels under sunlit conditions.Experimental results indicate that the tracking control strategy employing dual-mode switching achieves a more optimal angle of solar incidence and irradiance intensity,thereby significantly improving the power generation efficiency of the photovoltaic system.
