How many kilowatt-hours of electricity can a wind turbine generate when its windmill rotates once? After reading this, I gained more knowledge
Speaking of electricity, nothing in our lives such as playing games or watching TV can be separated from electricity. In the past, people used to burn coal and other fuels to generate electricity, but the use of thermal power generation will have a huge impact on The environment caused great damage, so people began to use hydropower, wind energy, solar energy and other methods to generate electricity. Hydropower holds up half of the sky in our daily electricity consumption. For example, the annual power generation of the Three Gorges Hydropower Station is as high as 90 billion kilowatt hours.
When it comes to wind power generation, many people find it interesting. We all know that each wind energy generator is equipped with three fan blades. It looks like a large windmill and has a strange shape. These fan blades do not rotate very quickly, so some people think that it takes only one revolution. The amount of electricity generated is very small, so do you know how much electricity these big windmills can generate when they rotate once?
According to the different rotation axes of wind energy generators, wind energy generators are divided into horizontal axis wind turbines and vertical axis wind turbines. The principle of wind turbine power generation is actually very simple. The huge blades of the wind energy generator are blown to generate kinetic energy, which is then converted into electrical energy through the internal generator. During this conversion process, no harmful substances are produced, so the earth's environment can be well protected.
Among all wind energy generators, depending on the power of the wind energy generator, the electric energy generated by each rotation of the wind energy generator 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 it takes 3.5 seconds for the fan blades to rotate once. 60 minutes is 3,600 seconds, so the amount of electricity generated by the generator per second is 0.56 degrees, then the electricity generated by the wind turbine fan for each rotation is 0.56×3.5 seconds, which is 1.94 kilowatt-hours of electricity.
