How many kilowatt-hours of electricity does a wind turbine fan blade rotate once?

Introduction How many kilowatt-hours of electricity does a wind turbine fan blade rotate once? The wind turbine blades used for wind power generation do not rotate very quickly, so some people think that the electric energy generated by one rotation is very little. Th

How many kilowatt-hours of electricity does a wind turbine fan blade rotate once?

The blades of windmills used for wind power generation do not rotate very quickly, so some people think that the electric energy generated by one revolution is very little. Do you know that these large windmills rotate once? How much electricity can a circle generate? Let’s find out together.

Power of wind turbine

Among all wind energy generators, depending on the power of the wind energy generator, the amount of energy produced by the wind energy generator each time it rotates Electric energy is also different. For example, the most common 2MW direct-drive wind energy generator. When the wind energy is sufficient and stable, the wind motor can generate 2,000 degrees of electricity every 60 minutes, and each rotation of the fan blade takes 3.5 seconds. time, 60 minutes is 3600 seconds, so the electricity generated by the generator per second is 0.56 kilowatt-hours, then the electricity generated by the fan of the wind energy generator for each rotation is 0.56?3.5 seconds, which is 1.94 kilowatt-hours of electricity.

Classification and principles of wind turbines

According to the different rotation axes of wind energy generators, wind energy generators are divided into There are two types of horizontal axis wind turbines and vertical axis wind turbines. The principle of wind turbine power generation is actually very simple. The wind blows the huge blades of the wind energy generator to generate kinetic energy, which is then converted into energy through the internal generator. electrical energy.

Generally speaking, wind turbines are divided into horizontal axis wind turbines and vertical axis wind turbines according to the different rotation axes. The most common 2MW direct-drive wind energy generator can generate 1.94 kilowatt-hours of electricity per revolution under the condition of recombination of wind energy.
