82m, 77m, 90m.
The length of wind turbine blades is generally: 1. Different fan models are different, with diameters of 82, 77 and 90. In meters, 1.5 MW fan turbines will from 65 m to 88 m, including IECI category: 65 m, 70 mIECII category: 77 m, 82 mIECIII category: 82 m, 86 m, 88 m2MW 2. The total diameter of the turbine is now generally between 80 meters and 105 meters or ; yes, but the length of the blade is 40 or 50 meters.
Wind turbine blades can measure up to 80 meters long.
The largest wind turbine in the world 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 (blade length included), 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 produce 260,000 kWh of electricity in 24 hours, enough to meet the electricity consumption of hundreds of homes for a month.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, generator, steering, tower, speed limiting safety mechanism and energy storage device. The operating principle of a wind turbine is relatively simple. Wind action. The kinetic energy of the wind is converted into the mechanical energy of the wind rotor shaft, and the generator rotates under the drive of the wind rotor shaft to produce electricity.
Principle of the wind turbine
It is an electrical device thati converts wind energy into mechanical energy and mechanical energy into electrical energy. Generally speaking, it is a thermal energy engine that uses the sun as the heat source and the atmosphere as the working fluid. Wind power generation uses natural energy, which is much better than diesel power generation. But if used in an emergency, it is still not as efficient as a diesel generator. Wind power is not considered a backup energy source, but it can be used long term.
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 start at a breeze speed of approx.n three meters per second (the breeze level). Wind energy is becoming a craze around the world because it poses no fuel problems and does not produce radiation or air pollution.
