The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, and then use a speed multiplier to increase the rotation speed to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can start at a wind speed of around three meters per second.
Principle
The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then to use a speed multiplier to increase the rotation speed to produce electricity. The engine produces electricity; it consists of a nose, rotor, tail and blades. The functions of each part are as follows: The blades are used to receive wind energy and convert it into electrical energy through the motor. the nose; the tail holds the bladesfacing the direction of the incoming wind to obtain maximum wind energy; the rotor allows the nose to rotate flexibly to adjust the direction of the tail is a permanent magnet and the stator winding; cuts magnetic lines of force to generate electrical energy.
Due to the unstable air volume, the wind turbine produces 13-25V alternating current, which must be rectified by the charger and then the battery is charged, so that the electrical energy generated by the wind turbine becomes 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.
Advantages and DisadvantagesAdvantages
1. Wind energy is a clean energy source.
2. Wind power installations are improving day by day and mass production is reducing costs. In app locationsHowever, the cost of wind power generation is lower than that of other generators.
3. Wind turbine installations are mostly non-three-dimensional installations that can protect the earth and ecology.
4. Wind energy is a renewable energy source, very environmentally friendly and very clean.
5. Wind power is energy efficient and environmentally friendly.
Disadvantages
1. The ecological problem with wind power is that it can disturb birds. For example, grouse in Kansas, United States, have gradually disappeared. . The current solution consists of producing electricity at sea, which is more expensive but also more efficient.
2. In some regions, the profitability of wind energy production is insufficient: In many regions, wind energy is intermittent. What's worse is that in placeslike Taiwan, in summer and during the day, when energy demand is needed. is high, wind energy is less time consuming; we must wait for energy storage technologies such as compressed air to develop.

3. Wind energy production requires a large amount of land to build wind farms to produce relatively large amounts of energy.
4. When wind power is generated, the wind turbine will make a huge noise, so it is necessary to find open places to build.
5. Current wind power generation is not yet mature and there is still considerable room for development.
6. Wind speed and the amount of energy generated are unstable.
7. The use of wind energy is seriously limited by geographic location.
The difference is huge! Look at this I said it! Basically, wind turbinesThey obtain wind energy and the thermal units are powered by the combustion of coal. Wind turbines are easy to cut. Thermal units are large and have a lot of complex support equipment. The basic performance of the fan depends on the unstable face of God. The power of the thermal units is stable. Wind turbines are located at high altitude and thermal power plants are underground. Wind turbines are not complicated. The squirrel cage is asynchronous and doubly powered. Both DC permanent magnets are available. This problem is too big. The advantage of wind energy is that it is clean energy and does not consume resources. No broadcast is produced. However, production is unstable, which impacts the stable operation of the power grid. Fire and electricity are the opposite!
