Introduction Red Hulu wind power generation, level 3 wind power, the number of watts is between 3,000 and 5,000 kilowatts. According to the query on Aigou.com, since the wind speed range of category 3 winds is relatively narrow, the wind speed of category 3 winds is

Red Hulu wind power generation, level 3 wind, how many watts

Between 3,000 and 5 kilowatts. According to the query on Aigou.com, since the Category 3 wind speed range is relatively narrow, Category 3 wind turbines also have certain power restrictions. Generally speaking, for Category 3 winds, the power carried by wind turbines must be less than 5 kilowatts, generally between 3 and 5 kilowatts. Of course, this number is not absolute and the specific power limit must be calculated based on factors such as the different characteristics, design and technical level of the wind turbines.

Wind levels are divided into several levels

Level 8

Wind force refers to the force of the wind blowing on objects . Generally, the wind force is divided into 18 levels according to the different phenomena caused by the wind blowing on objects on the ground or water surface, the minimum being level 0 and the maximum being level 17.

In terms of meteorology, wind is generally divided into twelve levels according to its strength:

1 Level 0 wind is also called calm wind.

2. Level 2 wind is called light breeze, the leaves make a slight sound, and the face is windy.

Level 3 and 4 winds are called gentle breezes. Tree branches shake, which can blow dust and paper onto the ground.

Level 4 and 6 winds are strong, large branches sway, power lines whir, and it is difficult to walk with an umbrella.

Winds of levels 5 and 8 are called strong winds. Tree twigs may be broken, and the resistance to walking in the wind is very great.

6. Level 10 winds are called squall winds and are rare on land. They can uproot trees and cause serious damage to buildings.

7. Winds above level 12 are called typhoonsor hurricanes, which are extremely destructive and rarely seen on land.

Principles of wind power generation

Convert the kinetic energy of wind into mechanical kinetic energy, and then convert the mechanical energy into kinetic energy electric. 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 use a speed multiplier to increase the rotation speed to induce the generator to produce electricity. According to current wind turbine technology, electricity production can begin at a breeze speed of around three meters per second (the degree of breeze). Wind energy is becoming a craze worldwide because it does not require the use of fuel and does not produce radiation or air pollution.

The devices necessary for productionwind 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 iron tower. (Large-scale wind power plants basically do not have tail rudders. Generally, only small power plants (including domestic types) have tail rudders.)

The wind wheel is a component important which converts the kinetic energy of the wind. in mechanical energy. It consists of two (or more) propeller-shaped wheels. 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. Currently, it is mainly made of fiberglass or other composite materials (such as carbon fiber). (There are also vertical wind turbines, S-shaped rotating blades, etc., which have thesame function as conventional propeller-type blades)

Since the speed of the wind turbine is relatively low and the magnitude and direction of the wind force often changes, making the unstable speed;Before driving the generator, a gearbox should be fixed to increase the speed to the rated speed of the generator, and a speed regulating mechanism should be added to keep the speed stable, and then connected to the generator. In order to keep the wind rotor always aligned with the wind direction to achieve maximum power, a tail rudder similar to a weather vane must be installed behind the wind rotor.

The iron tower is the structure that supports the wind wheel, rudder and generator. It is usually built relatively high in order to obtain a greater and more uniform wind force and to have sufficient force. The height of the tower depends on the impact ofs obstacles on the ground on the wind speed and the diameter of the wind wheel. It is generally between 6 and 20 meters.

The function of the generator is to transfer the constant rotation speed obtained from the wind wheel to the power generation mechanism through increased speed for uniform operation, thereby converting mechanical energy into electrical energy .

The wind level is divided into 18 levels.

The wind scale (wind scale), called wind level, is a method of expressing wind intensity. Wind force refers to the force exerted by wind blowing on an object. Generally, wind force is divided into 13 levels according to different phenomena caused by wind blowing over objects on the ground or water surface. The minimum is level 0 and the maximum is level 12. Winds at level 12 are particularly dangerous.

According to standardsNational data released by China in June 2012, based on the wind speed at a height of 10 meters at the standard weather observation site, the wind power level is divided into 18 levels. The commonly used units for expressing wind speed are nautical miles per hour, meters per second and kilometers per hour, respectively. The commonly used units for typhoon forecasting in China are meters per second. Wind is an important resource.

Advantages of wind energy

1. Environmental protection: Wind energy is a renewable and clean energy that does not produce pollutants or emit greenhouse gases. and has a low impact on the environment. Compared to traditional fossil fuel-based electricity generation, wind energy is more environmentally friendly.

2. Energy diversity: wind energy is a source ofAbundant energy that is not limited by geography or resources and can be widely used around the world. Wind energy can provide a diversified energy supply, reduce dependence on fossil fuels and improve energy security.

3. Economic Benefits: Wind power is an economically feasible source of energy. With the advancement of technology and the realization of economies of scale, the cost of wind energy has gradually decreased, becoming a competitive energy source. At the same time, wind energy can also generate jobs and tax revenue for the local economy.

4. Promote the development of renewable energy: Wind energy is an important part of the development of renewable energy. By promoting wind energy, we can promote the research, development and application of renewable energy technologies.uvelable and promote the transformation and modernization of the energy structure.
