The electricity generated by a 70 meter blade rotating once is about 1 to 2 degrees.
When the wind power is sufficient and stable, the wind engine can generate 2,000 kilowatt hours of electricity every 60 minutes, and it takes 3.5 seconds for the fan blades to run once in 60 minutes. is 3,600 seconds, the electricity generated per second is 0.56 kilowatt hours, and the electricity generated per rotation is 0.56 x 3.5 seconds = 1.94 kilowatt hours.
Wind power generation refers to the conversion of kinetic energy from wind into electrical energy. Wind power is a clean, non-polluting renewable energy that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity.
The 120 meter wind turbinee topgenerates approximately 2.5 kilowatt hours of electricity in a single turnAlthough the blade. the speed is not high, but the gearbox inside the generator can increase the speed of the high-speed shaft to 50 times that of the low-speed shaft. Based on a wind turbine's power output of about 1,500 kilowatt hours per hour, the wind turbine can generate 2.5 kilowatt hours of electricity when it spins once and then converts the energy wind turbine into electrical energy. converts it into usable electrical energy by inversion. The available electrical energy can then be used to operate electronic devices.
The principle of wind energy
A normal-sized wind turbine can generate an average of 1,200 kilowatt hours of electricity per hour in conversion. a large windmill spins once, it can generate about 1 kilowatt hour of electricity. The windmillt is limited by the material structure and is designed to have a maximum speed that will damage the windmill itself, or even destroy it completely.
The conversion of wind energy into electrical energy is also a complex process. In traditional wind turbines, after the blades rotate, the rotation speed is increased through several sets of gears such as speed multipliers to drive the generator to produce electricity. However, this method consumes a lot of energy, so another technology has been developed, direct drive permanent magnet technology.
