How tall are wind turbine poles?

Approximately 80 meters to 120 meters.

The height of the wind power pole is to use the strong wind at high altitude to generate more wind power to drive the generator to produce electricity. The height of wind turbine poles varies from 80 meters to 120 meters. This range aims to maximize the capture of wind energy at high altitudes, where wind speeds are relatively high. The height of wind poles is also considered by factors such as land use, environmental impact and economic costs.

Size of a wind turbine for wind power generation

One wind power generation cycle is equivalent to approximately 1.4 kWh.

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 speed of poiThe speed of the blades at this time can reach more than 280 kilometers per hour, comparable to the speed of a high-speed train) and can generate about 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 secwave, it is only 9.5 kilowatts.

The principle of wind energy production :

The principle is to convert the kinetic energy of the wind into mechanical kinetic energy, then convert mechanical energy to For electrical kinetic energy, it 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 necessary for the production ofwind 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.

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 ofthe wind wheel. It is generally between 6 and 20 meters.

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

How tall is the wind turbine in meters?

< strong>The dimensions of this type of wind turbine are as follows:< /strong>

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 metersres and 70 meters.

How tall is the windmill in a wind power plant?

Common wind turbines with circular towers are usually between 120 and 140 meters high, but they are prone to resonance. The current tallest is the 160m pre-stressed steel tube wind turbine tower, which improves the safety and service life of the tower. The four corners of the frame-type wind turbine tower have stronger bearing capacity through the lower tower body, which can effectively avoid resonance. In the future, it can continue to rise to 180 m or even 200 m, which will better obtain wind resources and improve the efficiency of power generation. Additional information: A wind turbine is an electrical device that converts wind energy into mechanical work, drives the rotation of the rotor, and ultimately produces alternating current. Wind turbines are generallyconsisting of a wind turbine, a generator (including devices), a direction regulator (tail), a tower, a speed limiting safety mechanism and a data storage device 'energy. The operating principle of wind turbines is relatively simple. The wind wheel rotates under the influence of the wind, and the wind converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to produce electricity. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. work.

This value has no fixed value and is mainly linked to two factors:

1. The power output of the wind turbine. The higher the output power, the higher its height.lifted. The hub height of 1500 kW wind turbines is 70 m, which is the most common.

2. It is linked to the parameters of the local wind resource. Generally speaking, the higher the altitude, the better the wind resource parameters. The specific height will only be determined after economic demonstration.
