How many kilowatt hours of electricity can a wind turbine produce per hour?

A one-megawatt wind turbine can produce about 1 kilowatt of electricity in one revolution.

A wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of blades, generators, mechanical components and electrical components. According to the different axes of rotation, wind turbines are mainly divided into two categories: horizontal axis wind turbines and vertical axis wind turbines. Currently, horizontal axis wind turbines occupy the dominant position in the market.

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 begin at a breeze speed of around three meters per second (the breeze level).

Detailed information:

< p> The small wind power generation system is very efficient, but it is not only composed of a generator head, but a small system with certain technological content: wind turbine + charger + digital inverter. The wind turbine consists of a nose, a rotor, a tail and blades. Each part is important, and the functions of each part are as follows: the blades are used to receive wind energy and convert it into electrical energy through the nose; the tail allows the blades to always face the direction of the wind to obtain maximum wind energy; the rotor allows the nose to rotate flexibly to reach the tail has the function of adjusting the direction; the nose rotor is a permanent magnet and the stator winding cuts the magnetic lines of force to generate electrical power.

For a windienne of 1.5 MW, the generator rotates approximately 1,800 times per minute, generates 1,500 kilowatt hours of electricity per hour and the turbine rotates approximately 18 times per minute. This is directly related to the size of the unit. Generally speaking, level 3 winds are useful 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; wind speed When the wind speed is 6 meters per second, it is only 16 kilowatts; when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the stronger the wind force, the greater the economic benefits.

There is no special meaning in Feng Shui to install a wind turbine on the roof of the building. The wind turbine installed on the roof is used to exhaust wind, dust and regulate the air during ventilation, it can prevent rain, snow, insects, noise and sand from the roof fan from entering the roof. piece. From a scientific perspective, having a wind turbine on the roof of a building has many benefits, but it has no connotations.
