It's very technical. First of all, it is necessary to calculate the size of the blades to be used, what is the transmission ratio of the gears, etc., and the electricity generated must be transformed and rectified.
It depends on the wind strength where you are. Generally, blades with a diameter greater than one meter are required. The manufacturing requirements for blades are relatively high. You need to find a variable speed gear and. a battery to store electricity. This is very inconvenient and relatively expensive considering that China has the largest SL5000 wind turbine in the world. I'm very proud of it. I would like to ask how long one of its fan blades is. It spins once during operation.
To make a wind turbine from a car generator, the speed of 120 rpm is far away. enough. It must be at least 800 to 1000. It can only produce electricity when it is rotating. If youdo not modify the generator and want to use it as a wind turbine, you need to increase the transmission ratio of the transmission gear. The higher it is, the better. , because you are the car's charging system and the system will automatically adjust. Yes, there will be no problem. You want the car engine to be running at least several thousand rpm at high speed and the generator will have no problems. The only thing you care about is whether the pneumatic system, bracket and transmission assembly you made can withstand the test under strong winds, haha.
The height of the fan generally depends on the blade. length and customer choice Likewise, generally the diameter of 5000 kW wind turbine blades is 100 meters or more, and the height is more than 80 meters.
A wind turbine is an electrical device that converts wind energy into workmechanical. 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. It converts 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 working fluid.
For many centuries, wind turbines, like hydraulic machines, oplayed 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 have become aware of the instability and limitations of conventional fossil energy supplies, so the search for clean and renewable energy has become a key issue in the modern economy. world. an important subject.
Wind power, as a renewable and non-polluting natural energy source, has once again attracted people's attention.
