In the case of rainy weather, the irradiance is not high, and the power generation of the photovoltaic power station will be very low. This kind of continuous rainy weather has made many friends who have installed photovoltaics start to worry. How can we ensure stable power generation and minimize the impact of rainy days?
As the world's leading new energy asset management service provider, Youde Operation and Maintenance is committed to providing standardized, safe and efficient power station operation and maintenance services to global customers. Based on years of professional operation and maintenance experience, Youde operation and maintenance has put forward scientific power station operation and maintenance suggestions on how to minimize the loss of power generation in bad weather.
1. The preliminary design and construction of the power station should not be ignored
When the power station is designed in the early stage, the selection of the appropriate site is very important for the power generation of the power station in the later stage. If the power station is built on flat ground, geographical and geological factors should be taken into consideration, such as the orientation of the terrain, the degree of slope fluctuation, hidden dangers of geological disasters, the depth of water accumulation, flood water level, drainage conditions, etc. Insufficient consideration of flood control in design, floods inundate the station during the flood season, resulting in heavy losses! Reasonable site selection can minimize the losses caused by objective factors.
Youde operation and maintenance recommends that a drainage system should be added scientifically. When designing a power station, it is necessary to fully consider the depth of water accumulation, drainage conditions and installation orientation. Many fishery and light complementary projects submerged equipment due to rising water levels, largely due to incomplete design considerations and poor drainage capacity, which led to tragedies. Therefore, when selecting a site, not only the cost, but also the safety of subsequent operations must be considered.
2. Equipment selection should not be sloppy
Dehumidification and moisture-proofing of electrical equipment at the station is a particularly severe task during prolonged rainy days. High humidity environment has a great impact on power equipment. If it is not handled properly, it may cause obstacles to equipment operation and even affect system security. For example, the inside of the inverter is easy to form wet dust with the dust in the air, which corrodes the electronic components inside the equipment and causes the equipment to be abnormal.
Generally speaking, a temperature and humidity meter should be installed in the high-voltage power distribution room to detect the indoor temperature and humidity in real time, and equipped with a dehumidifier to prevent such weather from bringing security risks to the equipment; mainstream photovoltaic equipment basically uses IP65 protection level, with waterproof Performance components, inverters, combiner boxes, etc.
In addition to comprehensively considering the high temperature and low temperature resistance of the equipment, you should also consider the waterproof and moisture-proof performance of the equipment and facilities, the convenience of equipment maintenance and operation, and do a good job of preventing moisture and dehumidification in advance, so as to improve the safe operation of the power station. .
3. Early prevention + timely response is indispensable
With the support of UniCare® operation and maintenance system independently developed by Youde Operation and Maintenance, the functions of basic information management and fault work order management of power stations can be realized. 80% of operation and asset management work are planned, such as planned inspections, Equipment maintenance, component cleaning, tool calibration, etc., the remaining 20% of emergencies can also be evaluated and analyzed at the first time and finally resolved.
Excellent operation and maintenance can make operation and asset management work standard, transparent, controlled, and assessable. 80% of the planned work can be effectively executed, greatly improving the efficiency of operation and maintenance, and greatly shortening the time from fault discovery to fault handling. Response time. Power generation failures caused by extreme weather or human factors, through 24-hour power station monitoring and cross-regional expert support, to ensure safe and stable operation of the power station and optimal power generation efficiency, power station operation and maintenance personnel can also respond quickly to prevent the situation from expanding. The loss of power generation is large, and the safety of assets and personnel is threatened.
Relying on high-quality operation and maintenance services, youde operation and maintenance is favored by customers. Up to now, Youde O&M has provided O&M services for more than 100 urban power stations in 28 provinces and cities across the country. The project types cover various power stations such as mountain, water, rooftop, agricultural light, and plateau, with a total operation and maintenance scale of 2GW.
