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

Introduction How many kilowatt hours of electricity can a wind turbine generate in one hour? A megawatt wind turbine can produce about 1 kilowatt of electricity in one revolution. Wind turbine is a device that converts wind energy into electrical energy.

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

A megawatt-class wind turbine can produce about 1 kilowatt of electricity when it rotates once.

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. Depending on the axis 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 mainstream position on the market.

The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of about three meters per second (the level of breeze).

Extended information:

Small wind power systems are very efficient, but they are not just It consists 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. Every part is important, and the functions of each part are: the blades are used to receive wind power 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 achieve The tail has the function of adjusting the direction; the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic lines of force to generate electrical energy.

For a 1.5MW wind turbine, the generator rotates about 1,800 times a minute, generates 1,500 kilowatt-hours of electricity per hour, and the impeller rotates about 18 times a minute. This is directly related to the size of the unit. Generally speaking, level 3 winds are valuable for utilization. However, from an economic and reasonable perspective, wind speeds greater than 4 meters per second are suitable for power 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; the 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.
