The dimensions of this windmill are as follows:
The 1500 KW wind wheel has a diameter of 77 m and a tower height of 65 m. The 2,500 kW and 3,000 kW wind rotors have a diameter of 90 m and a tower height of 100 m. Since August 18, 2023, 1,500 kW wind turbines have been the common model in China. Most wind turbine diameters are around 77 meters, but there are also 70 meters, 82 meters and 87 meters. The height of the tower is 65 meters and 70 meters.
How do wind turbines produce electricity?
Wind power generates about 1.4 kilowatt hours of electricity per cycle.
Take the example of a 1,500 kilowatt wind turbine. The unit's blades are approximately 35 meters long (approximately 12 stories high). Each rotation of the wind turbine takes about 4-5 seconds (but the peak speed of the blades at this time can reach more than 280 kilometers per hour, comparable at the speed of a high-speed train) and can generate approximately 1.4 kilowatt hours of electricity. . Under normal full power conditions, one day's electricity generation can be used by 15 families for a year.
Generally speaking, Category 3 winds are valuable for use. However, from an economic and reasonable point of view, wind speeds above 4 meters per second are suitable for electricity generation. According to measurements, a 55 kilowatt wind turbine has an output power of 55 kilowatts when the wind speed is 9.5 meters per second; when the wind speed is 8 meters per second, the power is 38 kilowatts when the wind speed is 6 meters; per second, the output power of the unit is only 55 kilowatts, which is 16 kilowatts and when the wind speed is 5 meters per second, it is only 9.5 kilowatts.
The principle of productionwind energy:
The principle is to convert the kinetic energy of wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy, this is 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 wind turbine technology, electricity production can start 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 needed to produce wind energy are called wind turbines. This type of wind turbine can be roughement divided into three parts: the wind wheel (including the tail rudder), the generator and the tower.
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 is often made of fiberglass or other composite materials (such as carbon fiber).
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 of ground obstacles on wind speed and the diameter of the wind wheel. It is generally between 6 and 20 meters.
The function of the generator is to convert the constant energy obtained from the wind wheel into The rotation speed is transmitted to the power generation mechanism for uniform operation by increasing the speed, thereby converting the mechanical energy into electrical energy.

How many meters is the longest fan blade of a wind turbine?
< p>Power generation principle
p>Convert wind kinetic energy into mechanical kinetic energy, and then convert mechanical energy into electrical kinetic energy. This is wind energy production. 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 technologylt of wind turbines, 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.
Due to the unstable air volume, 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 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.
Detailed information:
1. Horizontal axis wind turbine, the rotation axis of the wind wheel is parallel to the directionn of the wind;
2. Vertical axis wind turbine, the rotation of the wind turbine The axis is perpendicular to the ground or the direction of air flow.

1. Clean environmental benefits;
2. Renewable and never exhausted
3. is short and can be built on land or at sea;
4. The installed capacity is flexible and the operation and maintenance costs are low.

The longest wind turbine blade is 80 meters.
The largest wind turbine in the world is located in Maade, Denmark. It is called V164 and was manufactured and installed by Mitsubishi Vestas Offshore Wind Company. This wind turbine is 220 meters high (blade length included), with three giant blades installed on it. Each blade is 80 meters long, which is longer than a Boeing 747. In addition to being the largest, it is also the most powerful wind turbine in the world, in circon normal instances, it can produce 260,000 kWh of electricity in 24 hours, enough to meet the electricity consumption of hundreds of homes for a month.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, generator, steering, tower, speed limiting safety mechanism and energy storage device. The operating principle of a wind turbine is relatively simple. action of the wind. The kinetic energy of the wind is converted into the mechanical energy of the wind wheel shaft and the generator is used in the wind wheel. The shaft rotates to produce electricity.
Principle of the wind turbine
It is an electrical device that converts wind energy into mechanical energy and mechanical energyanic in electrical energy. Generally speaking, it is a thermal energy engine that uses the sun as the heat source and the atmosphere as the working fluid. Wind power generation uses natural energy, which is much better than diesel power generation. But if used in an emergency, it is still not as efficient as a diesel generator. Wind power is not considered a backup energy source, but it can be used long term.
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 breeze speed of around three meters per second (the breeze level). Wind energyis becoming a craze throughout the world because it poses no fuel problems and does not produce radiation or air pollution.
