光伏电站的运维需要一整套工具来保障运行安全与效率，按功能可分为以下几类。
Daily inspections are divided into two methods: remote monitoring and on-site inspections. Remote monitoring monitors the real-time operation status of equipment through the operation and maintenance cloud platform. When the power generation suddenly drops by more than 15% or the string current dispersion rate exceeds 5%, the system automatically alarms and pushes it to the operation and maintenance personnel. On site inspections focus on checking the cleanliness of component surfaces, the tightening of bracket bolts, and the operating status of inverters.
Component maintenance: The cleaning frequency is determined according to the type of environment. It is recommended to clean twice a year in industrial areas, and natural flushing can be used in rainy season areas, but the blockage of drainage channels needs to be checked. Soft rubber shoes and protective gloves should be equipped during cleaning. It is strictly prohibited to step on components and frames, and cleaning tools should not be placed on components.
Check the operation of the cooling fan, screen alarm codes (with a focus on PID and ISO faults), and AC side voltage fluctuation range (± 10% of rated voltage). Inverter cooling channel cleaning.
Check the sealing of the box, the status of the components, and the flexibility of the switch operation to ensure that the grounding resistance is not greater than 4 Ω. The surge protector should be in an effective state.
Check the tightening torque of the bolts. If the area of anti-corrosion coating detachment exceeds 5cm², repainting is required. Check whether the brackets and bridge frames are corroded or deformed, and there should be no water accumulation inside the bridge frames.
Drone inspection has become an important means of operation and maintenance for large power plants. Through the technology of "unmanned aerial vehicle+infrared/visible light+AI intelligent analysis", precise management from comprehensive investigation to hidden danger closed-loop can be achieved. The AI system can accurately identify hidden dangers such as hot spots, dirt, and occlusion, with a positioning accuracy of centimeter level.
By timely cleaning and dust removal, eliminating heat spot hazards, and optimizing inverter operating parameters, the power generation efficiency of the power station can be improved by 8% -10%.
Intelligent operation and maintenance methods can significantly reduce labor costs.
Regularly inspecting the deformation of component frames, glass damage, EVA delamination, back panel scratches, and other issues to promptly detect and address defects can effectively extend the service life of the equipment. Reduce equipment failure rate through preventive maintenance and ensure long-term stable operation of the power station.
Standardized operation and maintenance processes can effectively reduce operational risks. Standardize high-voltage operations by implementing the process of "power outage → electricity inspection → discharge → grounding → tagging"; Ensure that there is a dedicated person to supervise high-voltage operations through a two person homework system; Reduce the risk of electric shock and falling by using insulated tools and safety protective equipment.
