Since the gear ratio is 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.
How many kilowatt hours of electricity can a large wind power fan generate in a circle?
1. Generate 10,760 kW.
2. 2.5Mw wind turbine assembly When the generator set is at full power, the generator can generate 2,500 kW per hour. At this time, the fan impeller speed is 13.94 rpm. times 60 minutes. Then use 2500/(13.94*60)=10760Kw.
A large wind fan can generate 0.1 kWh of electricity in onesingle turn.
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 slower and the power output will be reduced accordingly. When the wind speed is high, the speed of the wheel iswind turbine 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-emission carbon and digital. 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 the market competitiveness and 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.
