Abstract

The invention provides a photovoltaic array state monitoring method, device and system adopting 5G, and relates to the technical field of photovoltaic power generation. The method is applied to a control center in communication connection with an unmanned aerial vehicle based on a 5G network, and comprises the steps that photovoltaic strings to be detected in a photovoltaic array serve as target photovoltaic strings in sequence, infrared images, sent by the unmanned aerial vehicle, of the target photovoltaic strings are received, and the target photovoltaic strings comprise a plurality of photovoltaic panels connected in series; the infrared image is analyzed, hot spot information of each photovoltaic panel in the target photovoltaic string is obtained, and the hot spot information comprises the highest hot spot temperature; and the hot spot danger level of the target photovoltaic string is obtained according to the hot spot information of each photovoltaic panel in the target photovoltaic string. Thus, the state of the photovoltaic array is monitored, so that corresponding measures can be taken in time when the photovoltaic string in the photovoltaic array is abnormal, manual fixed patrol is not needed, and the manual operation and maintenance cost can be saved.

Description

technical field [0001] This application relates to the technical field of photovoltaic power generation, in particular, to a method, device and system for monitoring the state of a photovoltaic array using 5G. Background technique [0002] Photovoltaic power generation technology is a technology that uses photovoltaic panels to convert solar energy into clean electrical energy, and has been widely used in recent years. Photovoltaic power plants require a large number of photovoltaic panels (ie, photovoltaic panels), but due to foreign objects during use and defects in the manufacturing process, serious local temperature rises are prone to occur on photovoltaic panels, that is, hot spots. The emergence of hot spots will affect the power generation efficiency of photovoltaic power plants, reduce the actual service life of photovoltaic panels, and may cause fires and failure of photovoltaic arrays in severe cases, which is a problem that needs to be paid close attention to. Th...
