Photovoltaic power station in-station inspection
First, the importance of inspection.
Photovoltaic power stations are facilities that convert solar energy into electrical energy, and are widely used in the energy field because of their clean and renewable characteristics.
However, after the long-term operation of the photovoltaic power station, the equipment may appear wear and age, which will seriously affect the power generation efficiency and safety of the power station.
Therefore, it is very important to carry out regular in-station inspections of photovoltaic power plants.
Second, the content of the inspection.
1.Cleaning and inspection.
The photovoltaic panels of the photovoltaic power station are the key components, which directly receive solar energy and convert it into electricity.
However, prolonged open-air operation can lead to the accumulation of pollutants such as dust and sand on the surface of photovoltaic panels.
The accumulation of these pollutants will reduce the light transmission of photovoltaic panels, affecting the absorption efficiency of solar energy.
Therefore, cleaning inspection is an indispensable link.
2.Equipment checks.
In addition to the cleaning of photovoltaic panels, there are many other equipment in photovoltaic power plants, such as inverters, battery packs, cables, etc.
After a long period of operation, these equipment may have problems such as wear, aging, and failure.
Therefore, inspectors need to carry out detailed inspections of these devices to ensure that they are operating properly.
3.Security checks.
In photovoltaic power plants, safety issues such as formaldehyde, temperature, and fire require special attention.
Inspectors need to check whether the safety facilities of the photovoltaic power station are in good condition, such as firewalls, fire extinguishers, etc.
In addition, it is also necessary to pay attention to whether the equipment has potential safety hazards such as short circuit and leakage.
Third, the frequency of inspection.
The frequency of in-station inspections of photovoltaic power plants should be determined according to factors such as the scale, operating time and environmental conditions of the power station.
Generally speaking, it is more appropriate for PV power plants to be inspected once a month, and small PV power plants can be extended to once a quarter.
Of course, if a serious problem is found with the device, it should be repaired and replaced immediately.
Fourth, the inspection process.
1.Formulation of inspection plan.
Before the inspection, it is necessary to formulate an inspection plan and clarify the content, frequency and responsible person of the inspection.
The inspection plan should be formulated according to the characteristics of the power station to ensure the comprehensiveness and pertinence of the inspection.
2.Training of inspection personnel.
Inspectors need to be trained to be familiar with the equipment and inspection process of photovoltaic power plants.
They need to understand the characteristics and common problems of photovoltaic power plants in order to accurately judge the status of the equipment.
3.Inspection operations.
Inspectors need to inspect each part and equipment of the photovoltaic power station in turn according to the inspection plan.
During the inspection process, they need to carefully observe, record, and identify problems in time.
4.Inspection report.
After the inspection, the inspector needs to sort out the inspection report and record the problems found in the inspection process and the treatment methods in detail.
The inspection report can provide a reference for subsequent maintenance and improvement.
