Wind power affects local climate Wind power is the use of wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of energy must produce or consume another type of energy. Therefore, the energy production process of wind turbines must consume part of the wind energy present in the atmosphere. As an important factor in climate change, changes in wind energy will inevitably lead to climate change.
When some offshore wind farms and inland wind farms are operating, if the humidity is relatively high, a huge tail of water vapor will condense behind the wind turbine, which may affect the local microclimate, such as humidity, sand and dust have an impact.
Accidents are likely to occur when wind turbine blades are damaged. When the blades of thewind turbine are subject to strong winds greater than 25 m/s (wind speed cut), although the wind turbine is stopped. In severe cases, the entire blade may fly away.
Causes casualties and damage to buildings on the road (although wind turbines are mainly located in coastal areas with sparsely populated areas). In addition to extreme winds, blade surface corrosion, lightning strikes, ice cover, cracks, etc. can occur. can easily cause blades to break, causing accidents and affecting public safety.
Detailed information
Due to the unstable air volume, the wind turbine produces alternating power which varies from 13 to 25 V, which must be rectified by the charger. then charging the storage battery converts the electrical energy generated by the wind turbine into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the bBattery powered by AC 220 V mains power to ensure stable use.
Usually people think that the power of wind power is entirely determined by the power of the wind turbine, and they always want to buy a bigger wind turbine, but this is incorrect. The current wind turbine only charges the battery, and the battery stores electrical energy. The amount of electrical energy ultimately used is most closely related to the size of the battery.
The power mainly depends on the air volume, not just the power of the machine head. On the continent, small wind turbines are more suitable than larger ones. Because they are more easily driven by small winds to produce electricity, small continuous winds can provide more energy than temporary strong winds.
When there is no wind, people can still use the electricity brought by the wind normally. AutIn other words, a 200 W wind turbine can also be used with a large battery and an inverter to get 500 W, or even 1000 W. or even more.
Baidu Encyclopedia - Wind Power
The amount of wind power a wind turbine can handle has little to do with the W number of the wind turbine itself . say, a 300 W wind turbine can be as different as a 20 kW wind turbine. The wind resistance of wind turbines is the same, but large wind turbines are larger and more reliable, which has a greater relationship with the performance of the wind turbine itself. /p>
The wind resistance of general wind turbines is dynamically 25 M/S. Left and right statics are approximately 50 M/S
