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 force, the greater the economic benefits.
The amount of electricity generated is equal to the amount of solar radiation received by the inclined surface.
After querying the State Grid, power generation = solar radiation × total panel area × component conversion efficiency × 0.28 × system efficiency.
The annual theoretical power generation is the estimated total electric energy produced by a wind turbine within a year using the power curve and hub height to represent the annual wind speed frequency distribution.
