The specified operating wind speed range for wind turbines is generally

3 ~ 25 m/s. Because it is necessary to protect the safety of wind turbines and provide appropriate customs, the specified operating speed range of wind turbines is generally 3-25m/s. The general start-up wind speed of wind turbines is 3 to 4 m/s, and the cut-off wind speed, that is, the wind speed when stopping in strong winds, is 19 to 25 m/s. The so-called standard time refers to the total wind generated by the wind turbine, which is generally 11 to 15 m/s. If it can reach 2,000 standard hours per year, it is an area with rich wind resources.

Four major risks of wind power generation

Wind power generation will destroy the environment, harm the climate and cause noise pollution, as follows :

1 .Wind energy production will harm the local ecological environment, for example by destroying vegetation, changing topography, proreferring to soil erosion and land desertification.

2. Wind energy affects the local climate. Wind energy uses wind energy present 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, wind turbines The process of generating electricity is inevitable.

3. The environment around the wind farm is good, so it will become a paradise for many birds, but a large number of birds will be injured by the wind turbines.

The four main risks associated with wind energy production are: noise risk, landscape damage, interference with wildlife and impact on local climate .

1. Noise Risk: In fact, wind turbines will indeed cause many unavoidable risks during their operation. However, for the use and developmentnt of any type of energy, there can be many. will cause damage to nature.

2. Landscape Damage: Because wind turbines are usually large and must be built in open areas, they often destroy beautiful mountains, beaches, and farmland. This will not only affect the living environment of local residents, but will also have a negative impact on the tourism industry. Many attractions have become difficult to enjoy due to the construction of wind turbines, and this is an issue that deserves attention.

3. Interference with wildlife: Low-frequency noise and electromagnetic radiation from generators can disrupt the living and migration patterns of sensitive animals. Some studies suggest that the operation of wind turbines can cause nearby wildlife to decline or migrate elsewhere in search of safe habitat.

4. Impact on local climateal: Wind energy uses wind energy present 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.

The working principle of wind power generation

Convert the kinetic energy of wind into mechanical kinetic energy, and then convert the mechanical energy in electrical kinetic energy This is the production of wind energy. The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then the rotation speed is increased through a speed multiplier.esse to encourage the generator to produce electricity. Depending on wind turbine technology, electricity production can begin at a breeze speed (the degree of breeze) of around three meters per second.

The devices needed to produce wind energy are called wind turbines. This type of wind turbine can be roughly divided into three parts: the wind wheel (including the tail rudder), the generator, and the tower. Large-scale wind power plants generally do not have a tail rudder, and usually only small wind power plants (including domestic types) do.

The wind wheel is an important element that converts the kinetic energy of the wind into mechanical energy. It is made up of several blades. When the wind blows toward the blades, an aerodynamic force is generated on the blades to rotate the wind wheel. The blade material requires high strength and light weight and ist often made of fiberglass or other composite materials (such as carbon fiber).
