Wind power generation is lower carbon and environmentally friendly. Wind is a product of nature. It exists whether it is used or not. As long as you set up wind power generation equipment, you can generate electricity. Moreover, wind power generation equipment is simple and easy to install, and there is no need to specially develop the environment. , keeping the environment completely intact.
Hydroelectric power generation requires the construction of dams and changes to the natural environment, which changes the surrounding ecological balance and may have a certain impact on the local ecosystem.
So, wind power is lower carbon and environmentally friendly.
The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of approximately three meters per second.
Principle
The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to generate electricity. The engine generates electricity; it consists of a nose, a rotor, a tail, and blades. The functions of each part are: the blades are used to receive wind power and convert it into electrical energy through the nose; the tail keeps the blades facing 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; the rotor of the nose 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 outputs alternating current of 13 to 25V, 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 power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.
Advantages and DisadvantagesAdvantages
1. Wind energy is a clean energy source.
2. Wind energy facilities are improving day by day, and mass production reduces costs. In appropriate locations, the cost of wind power generation is lower than that of other generators.
3. Wind energy facilities are mostly non-three-dimensional facilities that can protect the land and ecology.
4. Wind power is a renewable energy source, very environmentally friendly and very clean.
5. Wind power is energy-saving and environmentally friendly.
Disadvantages
1. The ecological problem of wind power is that it may disturb birds. For example, the grouse in Kansas, USA, have gradually disappear. The current solution is offshore power generation, which is more expensive but also more efficient.
2. In some areas, the economics of wind power generation are insufficient: wind power in many areas is intermittent. What is worse is that in places such as Taiwan, in summer and during the day when power demand is high, wind power is Less time; must wait for energy storage technologies such as compressed air to develop.

3. Wind power generation requiresA large amount of land is needed to build wind farms to produce relatively large amounts of energy.
4. When wind power is generated, the wind turbine will make huge noise, so it is necessary to find some open places to build.
5. Current wind power generation is not yet mature and there is still considerable room for development.
6. The wind speed is unstable and the amount of energy generated is unstable;
7. The utilization of wind energy is seriously restricted by geographical location.
