100 square meters. The wind power transmission tower covers an area of 100 square meters. A 4.2 MW wind power plant occupies about 100 square meters. 100 square meters is equal to 0.15 acres of land. Wind power generation refers to converting the kinetic energy of the wind into electrical energy. Wind energy is a Clean and pollution-free renewable energy has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity.
Wind turbine blades can be up to 80 meters long.
The world’s largest wind turbine is located in Maade, Denmark. It is called V164 and was manufactured and installed by Mitsubishi Vestas Offshore Wind Company. This wind turbine is 220 meters high (including the length of the blades), with three giant blades installed on it. Each blade is 80 meters long, which is longer than a Boeing 747. In addition to being the largest, it is also the most powerful wind turbine in the world. Under normal circumstances, it can generate 260,000 kWh of electricity in 24 hours, which is enough to meet the electricity consumption of hundreds of households for one month.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Wind turbines generally consist of wind wheels, generators, diverters, towers, speed limit safety mechanisms, energy storage devices and other components. The working principle of wind turbines is relatively simple. The wind wheel rotates under the action of wind, and it rotates the wind turbine. The kinetic energy of the wind is converted into the mechanical energy of the wind rotor shaft, and the generator rotates under the driving of the wind rotor shaft to generate electricity.
Principle of wind turbine
It is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. Broadly speaking, it is a heat energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power generation uses natural energy, which is much better than diesel power generation. But if it is used for emergencies, it is still not as good as a diesel generator. Wind power is not considered a backup power source, but it can be used for the long term.
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 wind turbine technology, power generation can start at a breeze speed of about three meters per second (the level of breeze). Wind power is becoming a craze around the world because it has no fuel problems and does not produce radiation or air pollution.
