The value of photovoltaic power station operation and maintenance: Operation and maintenance work is directly related to whether the power station can operate normally and stably for a long time, and is related to the operation and maintenance cost, investment value and final income of the photovoltaic power station.
⚫Safety management, effectively prevent and reduce safety problems caused by the aging of photovoltaic power stations in the later period, and ensure the safety of personnel and equipment;
⚫Use management methods and technical means to improve operation and maintenance levels, eliminate power station equipment defects, reduce failure rates, reduce power losses, and ensure normal and efficient operation of equipment;
⚫Guarantee revenue (power generation, PR value), achieve maximum revenue at minimum cost;
⚫Use optimization methods to increase power generation and increase asset value;
⚫Feedback on operation and maintenance experience to improve the optimal design of the power station;
Difficulties in operation and maintenance of distributed photovoltaic power stations
Although operation and maintenance is important, distributed power station operation and maintenance still encounters challenges.
The installed capacity of a single roof is small, the power stations are scattered, and the operation and maintenance workload is heavy;
Blindly pursuing installed capacity, no operation and maintenance channels are reserved between square arrays, which brings challenges to later string inspection and replacement;
Most of the colored steel tile roofs are laid flat along the roof. Some roofs only have ladders, which are difficult to clean;
The shadow range of roof obstructions was not fully considered, resulting in serious shadow blocking;
The on-site survey did not fully consider the impact of the enterprise and the surrounding environment, resulting in dust or chemical pollution;
Some distributed power stations use inventory components, which suffer from serious attenuation and large mismatch losses; the system PR does not meet expectations.
During construction and installation, the colored steel tile roof was stepped on, causing the roof to leak;
Due to the decline in the company's own production and operation capabilities, for the spontaneous self-use model, the company's load is reduced
Low, indirectly causing the power factor to fail to meet the standard, and the company faces fines.
The frequency of equipment failures is high, after-sales maintenance is not timely, and spare parts are not kept up;
Problems with untimely payment of subsidies and settlement of electricity bills;
Involving the interests of all parties, it is difficult to intervene in operation and maintenance from the development and construction stages;
Common faults of photovoltaic power stations
Photovoltaic power stations have an operating period of more than 25 years. Material aging and equipment failure often occur. In addition, there may be congenital design and construction defects, which have a serious impact on the power generation capacity of the power station, thereby affecting the income. Scientific and standardized operation and maintenance are required. to troubleshoot and reduce losses.
Photovoltaic power station safety hazards
The safety of photovoltaic power stations is related to people and property. It is necessary to eliminate safety hazards through operation and maintenance, avoid safety accidents, and take precautions before they happen.
