Photovoltaic array anomaly judgment method based on power generation prediction, medium and equipment

Abstract

The invention provides a photovoltaic array abnormity judgment method based on power generation prediction, a medium and equipment, and the method comprises the steps: carrying out the collection of photovoltaic power generation basic data, carrying out the large region division, setting a photovoltaic array, predicting the power generation amount of each large region in a preset time period, and obtaining the actual power generation power of the photovoltaic array. If the large-area power generation in the photovoltaic array is abnormal, judging an abnormal position until the power generation of the photovoltaic single board is abnormal; the implementation method is applied to a computer readable storage medium and computer equipment. According to the invention, the judgment of the abnormal power generation of the photovoltaic array is more accurate, the photovoltaic single board is easier to position, the damaged photovoltaic single board can be processed in time, and greater loss is avoided; human experience level requirements for material purchasing quantity judgment and related data statistics time are reduced, the purchasing quantity is more accurate, and stock overstock is reduced; manpower and material resource investment of regular inspection is reduced, abnormal conditions can be found more timely and accurately, and photovoltaic power generation safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical digital data processing, in particular to a method, medium and equipment for judging abnormality of photovoltaic arrays based on power generation prediction under ultra-short-term photovoltaic conditions. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It connects solar cells (photovoltaic veneers) in series and encapsulates them for protection, which can form large-area solar cell modules (photovoltaic arrays), Then cooperate with components such as power controller to form a photovoltaic power generation device. [0003] In addition to other unstable factors of photovoltaic power generation, if there are obstacles on the photovoltaic panel during the photovoltaic power generation process, it is easy to cause a fire due to uneven heating, espec...

Problems solved by technology

[0003] In addition to other unstable factors of photovoltaic power generation, if there is a shelter in the photovoltaic panel during the photovoltaic power generation process, it is easy to cause a fire due to uneven heating, especially in the scene of photovoltaic arrays, the consequences are more serious, which will lead to Damage of large photovoltaic panels one by one

[0004] In the existing technology, the traditional way to deal with this situation is to find out through artificial regular inspections or inspections by drones, which requires continuous investment of a large amount of manpower and material resources for inspections, which is costly and In fact, the investigation is very difficult, and it is difficult to find the single board with the problem in the first place; in addition, some technical solutions propose to compare the power generation differences of different photovoltaic panels to find abnormal solutions. However, due to the external factors of different photovoltaic panels Different, the power generation efficiency itself is different, this method cannot accurately find the problem of the photovoltaic array to a large extent
