This depends on the power of the wind turbine. If the wattage is large, the power generation will be large; if the wattage is small, the power generation will be small. China's largest wind turbine is 2 megawatts, with a daily power generation equivalent to 11 tons of high-quality coal.
The generator rotates one or two thousand revolutions per minute, while the wind turbine only generates one thousand kilowatt hours of electricity per hour. This is directly related to the capacity of the unit.
For example, in a 1.5-megawatt wind turbine, the generator spins about 1,800 revolutions per minute, producing 1,500 kilowatt-hours per hour, and the impeller spins about 18 times per minute.
This is related to factors such as the type and capacity of the fan and the speed of the generator.
For example, for a 2MW direct-drive wind turbine, its permanent magnet generator reaches the rated speed, such as 17 revolutions per minute, and it takes 60/17=3.5 seconds to make one revolution. If a 2MW wind turbine generates electricity continuously for 1 hour at rated speed, the amount of electricity generated in 3.5 seconds is 3.5*2000/3600=1.94 kilowatt hours, which is how much electricity is generated in one revolution.
For doubly-fed fans, it is also related to the gearbox reduction ratio.
No, let me tell you roughly, the fan is 1500kw. If it's full, it will spin at 17 revolutions per minute. If you do the math, one rotation is 1.47 kilowatt-hours of electricity. This is just an approximation and is not accurate.
The power generation of a 750KW wind turbine is generally 300~500 degrees per hour (calculated based on wind power levels 3 to 4).
The rated power generation of the 750KW wind turbine is 750 degrees per hour, and the actual power generation depends on the actual wind power and wind volume. When the wind is level 3 to level 4 (the wind speed is about 5 to 8 meters per second), the output of the wind turbine is generally 40% to 60% of the designed output. When the wind is level 5 (the wind speed is about 9.5 meters per second), it can generally reach More than 90% output.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
Converting the kinetic energy of the wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy, this is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of approximately three meters per second (the degree of breeze).
Wind power is forming a craze in the world because wind power does not require the use of fuel and does not produce radiation or air pollution.
According to measurements, a 55-kilowatt wind turbine has an output power of 55 kilowatts when the wind speed is 9.5 meters per second; when the wind speed is 8 meters per second, the power is 38 kilowatts; the wind speed When the wind speed is 6 meters per second, it is only 16 kilowatts; when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the stronger the wind, the more economicalThe benefits are greater.
