The spring breeze blows the earth, and everything recovers, however, with the footsteps of spring comes the potential threat of five major natural disasters. Recently, according to @Ministry of Emergency Management, the Office of the National Disaster Prevention, Mitigation and Relief Committee and the Ministry of Emergency Management, together with the Ministry of Natural Resources, the Ministry of Water Resources, the Ministry of Agriculture and Rural Affairs, the China Meteorological Administration, the National Forestry and Grassland Administration and other departments and units, held a meeting to discuss and judge the national natural disaster risk situation in March 2024. According to the comprehensive analysis, with the increase of temperature, the national natural disaster risk situation in March is more complicated, the strong convective weather in some areas of East China and Central China increases, the risk of floods, hail disasters increases, and the Inner Mongolia section of the Yellow River will be opened in mid-March. The risk of low-temperature rain, snow and freezing disasters is higher in some areas such as Northeast China, Inner Mongolia and **; The risk of local geological disasters in East China, Central South, Southwest China, and Northwest China is high. Most provinces in the country have entered the spring fire prevention period, and some areas such as southwest and southern China have high forest fire danger levels; There may be 4-5 dust processes in the northern region.
March is a critical moment for PV power plants to be vigilant against five major natural disasters – sand, dust, forest fires, geological disasters, low temperatures, rain, snow and ice, and floods, wind and hail disasters. These disasters not only threaten the safe operation of photovoltaic power plants, but also directly affect the stability and economic benefits of energy. Therefore, strengthening protection and increasing vigilance have become the top priorities of the photovoltaic industry at present. 1. The "killer" role of sandstorms
Dust storms occur frequently in spring, and fine dust particles will not only reduce the power generation efficiency of photovoltaic modules, but also may erode the surface of the equipment, causing a series of failures. The plant staff needs to clean the components on a regular basis, using special cleaning tools to ensure that the sand and dust are completely removed. In addition, strengthen the tightness inspection of the equipment to prevent sand and dust from invading the inside of the equipment and causing greater damage.
2. The "fire crisis" of forest fires
In the spring, the weather is dry and dry, and the risk of forest fires increases dramatically. Photovoltaic power plants should be located in areas far away from flammable vegetation, and a wide isolation zone should be set around the power station to remove combustibles and reduce the risk of fire spread. At the same time, all open flames should be strictly prohibited inside the power station and fire source control should be strengthened. In addition, an intelligent fire early warning system is installed to monitor the surrounding environment in real time, and once a fire is discovered, an emergency response mechanism is immediately activated to ensure the safety of the power station.
3. The "clutches" of geological disasters
Geological disasters such as landslides and debris flows can have a serious impact on the infrastructure of photovoltaic power plants. In the design and construction stage of the power station, the geological conditions should be fully considered, and reinforcement measures such as pile foundation and underground diaphragm wall should be adopted to ensure a stable foundation. At the same time, slope monitoring should be strengthened to discover and deal with potential safety hazards in a timely manner. For areas with complex geological conditions, advanced technologies such as geological radar can be used for exploration to ensure the accuracy and reliability of the foundation design.
Fourth, the "cold test" of low temperature, rain, snow and ice
Although the temperature gradually warms up in spring, there is still a possibility that low temperatures, rain, snow and ice will hit suddenly. Photovoltaic power stations need to do a good job of insulation of equipment, install insulation materials, and prevent equipment from being damaged due to low temperature. At the same time, snow melting agent or snow removal equipment is equipped to clear the snow in time to prevent ice from affecting the equipment. In addition, heating devices can be installed under the PV modules to cope with extreme cold weather and ensure the normal operation of the equipment.
5. "Flood storms" caused by floods, winds and hailstorms
Spring is also a time when floods and hailstorms are common, which can lead to problems such as water ingress of equipment and collapse of supports. The photovoltaic power station should establish a sound drainage system to ensure that the rainwater is discharged in time; At the same time, the brackets and electrical equipment are strengthened to improve their wind and hail resistance. For areas prone to hailstorms, brackets and shields can be made of high-strength materials to enhance the resilience of the equipment.
In addition to the above-mentioned specific protective measures, photovoltaic power plants should also strengthen safety education and training for employees to improve their ability to respond to disasters and safety awareness. At the same time, a sound emergency plan and rescue system should be established to ensure that it can respond quickly and effectively when disasters occur.
