One rotation of the wind turbine can generate 1.96 kilowatt hours of electricity.
Different motors have different power ratings. When wind power is relatively stable, it can generally generate 2,000 degrees of electricity in 60 minutes, on average, it can generate 0.56 degrees of electricity per second. and a turn The amount of electricity that can be generated is 1.96 kWh. Of course, this data is not completely accurate and will be affected by the influence of wind and the stresses of the generator itself. Solar energy technology is not sufficiently mature and has not been used on a large scale due to its relatively high level. cost.
But many people are still engaged in research in this energy field, and this energy will also bring great changes to people's lives in the future. In the future, those with low conversion rates will. nefaste for the environment. There will also be negative effects on how electricity production will be gradually changed.
The principle of wind power generation
The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then increase the rotation speed using a speed multiplier to cause the generator to produce electricity. The blades are used to receive wind energy and convert it into electrical energy through the nose. The tail allows the blades to always face the direction of the incoming wind to obtain maximum wind energy. The pivot allows the nose to rotate flexibly to realize wind power. Tail direction adjustment function. The nose rotor is permanent magnet, the stator windings cut the magnetic lines of force to generate electrical energy.
As the wind volume is unstable, the wind turbine produces 13-25V alternating current, which needs to be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the The wind turbine is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.
There is a wind turbine, the wind receiving area of the wind blade is s, assuming that the efficiency of converting the kinetic energy of the wind into electrical energy through the wind receiving area s is eta, the air density is ρ, when the wind h3>
40 meters to 90 meters. According to the CCTV website, the length of wind blades ranges from 40 meters to 90 meters. Wind turbines convert wind energy into mechanical work. Mechanical work causes the rotation of the rotor and the production of alternating currenttif. It includes wind turbines and generators. devices), steering (tail), tower, speed limit safety mechanism and energy storage device and other components.
How many meters are the leaves of wind power generation
When wind power is converted into electrical energy, according to the law of conservation of energy, there is:
Among them: m=ρV=ρ?vtS The simultaneous solution is: P= < table style="display:inline-table;vertical -align:middle" cellpadding="-1" cellpacing="-1"> | ||

| 2 |
When the wind speed becomes 2 times, the power becomes twice < p>The answeris therefore:

The leaves of wind power plants grow between 34 meters and 88 meters. The length of a wind turbine's blades varies depending on the size and model of the wind turbine. Small wind turbines have blade lengths of several meters, while large commercial wind turbines can have blade lengths of several tens of meters. MW) For generators, the blade length is between 34 and 45 meters, and the corresponding tower height (hub height) is 65 to 100 meters. For a 2 MW wind turbine, the length of the blades is between 48 and 59 meters, and the corresponding height. the height of the hub is between 48 and 59 meters. The height of a 3 MW wind turbine is between 80 and 100 metersand the length of the blades is between 44 and 59 meters. The corresponding hub height is between 80 and 110 meters. The world's largest known wind turbine reached 88 meters, manufactured in a factory in Denmark. Wind power is the process of using wind energy to operate wind turbines and then converting the wind energy into electricity. This clean energy technology is widely used around the world as it helps reduce dependence on fossil fuels and reduces greenhouse gas emissions.
