Photovoltaic power station automatic inspection system based on unmanned aerial vehicle

Abstract

The invention relates to a photovoltaic power station automatic inspection system based on an unmanned aerial vehicle. The system is used for monitoring real-time operation condition of a photovoltaicpower station and detecting whether problems such as contamination and hot spots exist in a photovoltaic cell panel or not. The system comprises the unmanned aerial vehicle, a route design module, anonboard module, an image processing module, a communication module, a fault reconfirmation module and a ground workstation. The route design module is used for planning an inspection route of the unmanned aerial vehicle. The onboard module is composed of a camera and an infrared thermal imager and is used for collecting real-time images, pictures and thermal images of a photovoltaic module. The communication module is used for transmitting real-time data back to the ground workstation and receiving control instructions. The image processing module is used for processing image data and judgeswhether a fault exists in the photovoltaic cell panel or not. The fault reconfirmation module is used for carrying out fault reconfirmation on a suspected fault module, thereby preventing misjudgment.According to the system, the photovoltaic power station is automatically inspected, inspection efficiency is effectively improved, cost investment is reduced, and a fault point is discovered rapidly.

Description

technical field [0001] The invention relates to the field of inspection and operation and maintenance of photovoltaic power plants, in particular to an automatic inspection system and an implementation method based on a drone. Background technique [0002] According to the Medium and Long-Term Development Plan for Renewable Energy, China will strive to increase the installed capacity of solar power to 1.8GW by 2020 and 600GW by 2050. It is estimated that by 2050, China's renewable energy installed capacity will account for 25% of the country's installed capacity, of which photovoltaic power generation will account for 5%. It is estimated that before 2030, the compound growth rate of China's solar installed capacity will be as high as 25%. With the continuous development of solar technology and the layout of the national energy strategy, more and more photovoltaic power plants have been put into use. [0003] During the use of the solar panel, it will work abnormally due to...

Problems solved by technology

[0004] Photovoltaic power stations are mostly distributed in places with harsh environments such as deserts, Gobi, and grasslands, and they cover a large area and have a large number of equipment. If they rely on traditional methods for operation and maintenance, it will cause great cost waste for enterprises.
