It is not clear how many kilowatt hours of electricity A 120-meter blade generates, it depends on the specific power generation situation. Generally speaking, assuming the blade speed is 60 rpm, the electricity generated by a 120 meter blade is about 20 kWh. The wind turbine converts wind energy into electrical energy, and then converts it into usable electrical energy by inversion. The usable electrical energy can then be used to operate electronic equipment.
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. Simply put, wind power generation is the process of converting energyie wind turbine into mechanical energy, then conversion of mechanical energy into electrical energy. The blade is composed of many special-shaped interfaces of different sizes and shapes from the bottom to the tip. As fluid passes through the blade, it generates lift, which produces the most basic rotation.
A wind turbine consists of a nose, a rotor, a tail and blades. The functions of each part are as follows: the blades are used to receive wind energy and convert it into electrical energy through the nose; the tail keeps the blades facing the direction of the incoming wind. Thus, the maximum wind energy is obtained; the rotor allows the nose to rotate flexibly to realize the function of adjusting the direction of the tail. The nose rotor is a permanent magnet; , and the stator winding cuts the magnetic lines of force to generate electrical energy.
What is the torque at the blades of a10 KW wind turbine?
A large wind turbine fan can generate 0.1 kWh of electricity in a single revolution.
A 100 kW wind turbine generates 0.1 kWh of electricity per revolution at rated speed. Usually, 50W to 300W wind turbines are all 12V, and 300W to 800W wind turbines are all 24V. Above 800W, all wind turbines are above 36V.
Wind turbine speed is related to wind speed, size of the wind turbine, number and design of blades and other factors. According to statistics, the speed of wind turbines currently on the market is generally between 10 and 20 rpm, and the speed of large wind turbines is around 15 rpm.
Wind power generation is mainly affected by wind speed and rotational speed of the wind wheel. Generally speaking, when the wind speed is low, the rotation speed of the wind wheel will be slowerand energy production will be reduced accordingly. When the wind speed is high, the speed of the wind wheel will also increase and the power will be reduced. generation will also increase accordingly.
Wind power development trends
In the future, wind power development will be more intelligent, efficient, low-carbon , digital, etc.development direction. In terms of technology, the future will strengthen the reliability, safety and stability of wind turbines, improve the efficiency of wind power conversion, and make full use of digital technology and Internet of Things technology to achieve intelligent management and exploitation of wind energy production.
In terms of policies, support and policy guidance for clean energy will be strengthened in the future to improve market competitiveness and development.sustainable development of wind energy. In practical applications, wind power generation will be affected by many factors, such as topography, climatic environment, equipment maintenance, etc. Therefore, actual wind power generation may exhibit some fluctuations.
The speed ratio being 75, the blade speed is 20 rpm. The relationship between torque and power is T≈9.55P/n. (Note that the units are: Newton * meter, watt, revolution per minute) I'm not going to push it here. If you are interested, you can search for it on Baidu. According to the above formula, the torque T=9.55*10000/20=4775Nm can be calculated. This is simply a theoretical calculation, ignoring friction, iron loss and copper loss.
