Photovoltaic power station operation and maintenance inspection
I. Introduction. Photovoltaic power stations are devices that use solar energy to convert light energy into electrical energy, and as a clean and renewable energy source, its importance is becoming increasingly prominent.
However, with the expansion of the scale of solar power plants and the increase of installed capacity, operation and maintenance inspection is particularly important.
This article will focus on the operation and maintenance inspection of photovoltaic power plants, its importance, content and methods.
2. Importance.
The operation and maintenance inspection of photovoltaic power plants is an important part of ensuring the normal operation and power generation efficiency of photovoltaic power plants.
Through regular inspection, equipment failures, system abnormalities and other problems can be found and solved in time, and the stable power generation of photovoltaic power stations can improve power generation efficiency and extend the life of equipment.
At the same time, the inspection can also help the power station management personnel understand the operation and maintenance status of the power station, adjust the operation and maintenance strategy in time, and improve the management level.
Third, the content of the inspection.
The inspection of photovoltaic power plants includes three aspects: equipment inspection, system inspection and environmental inspection.
1.Equipment checks.
Equipment inspection mainly includes the appearance and internal inspection of photovoltaic modules, inverters, junction boxes, distribution cabinets and other equipment.
The visual inspection mainly includes checking whether the equipment is damaged, polluted, falling off and other phenomena;The internal inspection mainly includes checking whether the wiring of the equipment is firm and whether the connection is good.
In addition, it is also necessary to check the temperature, humidity, voltage, current and other parameters of the equipment, as well as check the operating status of the equipment.
2.System checks.
The system inspection mainly includes the monitoring system, communication system and data acquisition system of the photovoltaic power station.
The monitoring system needs to check whether it is operating normally and whether it can collect equipment operation data in timeThe communication system needs to check whether the communication between the devices is normal and whether the data transmission is stableThe data acquisition system needs to check the operating status of the data acquisition equipment and the accuracy of data acquisition.
3.Environmental inspections.
Environmental inspection mainly includes checking whether the surrounding environment of the photovoltaic power station affects the power generation efficiency.
For example, check whether there are trees blocking the sunlight of the photovoltaic modules, whether there is any weed accumulation that affects the heat dissipation of the device, etc.
Fourth, the inspection method.
The inspection of photovoltaic power plants can be combined with manual inspection and drone inspection.
1.Manual inspection.
Manual inspection is mainly carried out by operation and maintenance personnel, who visually inspect the appearance and internal condition of the equipment, and at the same time detect the operating parameters of the equipment with the help of instruments and equipment.
Manual inspection needs to be carried out in strict accordance with the inspection process and requirements to ensure the comprehensiveness and accuracy of the inspection.
At the same time, the inspection personnel need to have certain knowledge and skills, be able to operate the equipment proficiently, and judge the operation status of the equipment.
2.Drone inspection.
Unmanned aerial vehicle (UAV) inspection is the use of UAV technology to inspect photovoltaic power stations.
Equipped with a variety of sensors and cameras, drones can inspect photovoltaic modules, inverters and other equipment, the appearance and interior of the equipment, as well as the operation data and image information of the equipment.
