The length of the blades should be judged according tothe installed capacityof the wind turbine, such as V80, V52 and S70. The blade lengths of the three above. the models measure 39 meters and 25 meters, 34 meters respectively. The installed capacities are 1500, 850 and 1500 respectively. Therefore, the length of the blade should be judged according to the actual situation.
A wind turbine is an electrical device that converts wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device.
The operating principle of a wind turbine is relatively simple. The wind wheel rotates under the influence of the wind. Sheconverts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. driving the wind wheel shaft to produce electricity. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. work.
For many centuries, wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy to replace human and animal energy. The widespread application of electromechanical power in modern times and the discovery of oil deposits in the Middle East in the 1950s slowed the development of wind turbines.
In the early 1970s, due to the “oil crisis”, energy shortages appeared. People became awareence of the instability and limits of conventional fossil energy supply, so that the search for clean and renewable energy has become a key issue in the modern economy. world. an important subject. As a renewable and non-polluting natural energy source, wind energy has once again attracted attention.
How many meters is a large wind turbine blade?
The longest wind turbine blade is 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 cant 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 that converts wind energy into mechanical energy and mechanical energy into electrical energyque.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 around three meters per second (the breeze level). Wind energy is becoming a craze inthe whole world because it poses no fuel problems and does not produce radiation or atmospheric pollution.
40 meters to 90 meters. According to the CCTV website, the length of wind blades ranges from 40 meters to 90 meters. Wind turbines convert wind energy into mechanical work. Mechanical work causes the rotor to rotate and produce alternating current. It includes wind turbines and generators. devices), steering (tail), tower, speed limit safety mechanism and energy storage device and other components.
