It's just a theoretical thing. Assume: Under ideal conditions, solar energy is used to generate electricity during the day and wind energy is used to generate electricity at night. Electricity is available 24 hours a day. You think that in many places there is almost no wind at night, how is it possible to produce enough wind power? It is therefore a totally unreliable imaginary ideal state.
How much power does a 5 MW wind turbine generate per hour?
The power generated by a 750 KW wind turbine per hour is typically 300 to 500 degrees (calculated based on wind energy levels 3 to 4).
The rated power output of the 750 kW wind turbine is 750 degrees per hour, and the actual power output depends on the actual wind power and wind volume. When the wind is from level 3 to level 4 (the wind speed is approx.ron 5 to 8 meters per second), the power of the wind turbine is generally 40 to 60% of the designed power. When the wind is level 5 (the wind). speed is about 9.5 meters per second), it can generally achieve more than 90% output.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. 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 heat fluid. work.
Converting the kinetic energy of wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy, is wind power generation. The principle of wind power generation is to use wind energy to rotate the blades ofthe wind turbine, then using a speed multiplier to increase the rotation speed to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can begin at a breeze speed of around three meters per second (the degree of breeze).
Wind energy is gaining popularity around the world because it 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; 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 theThe economic benefits are significant.
The generator can generate approximately 5,000 kilowatt hours of electricity per hour.
A 5 megawatt wind turbine can produce approximately 5,000 kilowatt hours of electricity per hour. This is a theoretical quantity of electricity production. The actual amount of electricity production is slightly lower than this value.
The number of rotations of a 5 megawatt wind turbine in one hour is about 500, which can generate about 5,000 kilowatt hours of electricity, and the speed is between 12 and 20 revolutions per minute. At this speed, a 5 megawatt wind turbine can produce about 5 megawatt hours of electricity in one hour, which is equivalent to about 50,000 kilowatt hours of electricity.
