Approximately 200,000.
According to the 2023 market electricity pricing standard information, a wind turbine of more than 3 MW can produce 2.9 kilowatt hours of electricity. The price of one kilowatt hour of electricity is 0.5 yuan. power generation The machine can earn 1.45 yuan per revolution, 12 revolutions per minute and more than six hours of operation per day, so the monthly economic profit can reach about 200,000 yuan.
Wind power refers to the ability to convert kinetic energy into electrical energy. It is a clean, non-polluting renewable energy source with a relatively simple operating principle.
How many kilowatt hours of electricity can a large wind turbine generate when it spins once?
How many kilowatt hours of electricity can a wind turbine generate when its wind turbine spins once ? After reading this I gained more knowledge
Speaking of electricity, nothing in our lives, like playing games or watching TV, can be separated from electricity. In the past, people burned coal and other fuels to generate electricity, but the. The use of thermal power generation will have a huge impact on the environment and has caused serious damage. So people started using hydroelectric power, wind power, solar power and other methods to produce electricity. Hydroelectricity accounts for half of our daily electricity consumption. For example, the annual electricity production of the Three Gorges hydroelectric power station reaches 90 billion kilowatt hours.
When it comes to wind power generation, many people find it interesting. We all know that every wind power generator is equipped with three fan blades. It looks like a big windmillent and has a strange shape. These fan blades don't spin very quickly, so some people think it only takes one turn. the electricity produced is very small, so do you know how much electricity these large wind turbines can produce when they rotate once?
According to the different rotation axes of wind power generators, wind power generators are divided into horizontal axis wind turbines and vertical axis wind turbines. The principle of wind power generation is actually very simple. The enormous blades of. the wind power generator is blown to generate kinetic energy, which is then converted into electrical energy via the internal generator. During this conversion process, no harmful substances are produced, so the earth's environment can be well protected.
Among all wind power generators, depending on the power of the wind generatorwind power generator, the electrical energy generated by each rotation of the wind power generator is also different. For example, the most common 2 MW direct drive wind power. power generator, when the wind power is sufficient and stable, the wind motor can generate 2000 degrees of electricity every 60 minutes, and it takes 3.5 seconds for the fan blades to rotate once for 60 minutes , or 3,600 seconds, therefore the quantity of electricity generated. by the generator per second is 0.56 degrees, then the electricity generated by the wind turbine fan for each rotation is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity.
For a 1.5 MW wind turbine, the generator spins about 1,800 times per minute, generates 1,500 kilowatt hours of electricity per hour, and the turbine spins about 18 times per minute. minute. This is directly related to the capacity of the unit.
Generally speaking, winds de level 3 are valuable. However, from an economic and reasonable point of view, the wind speed is greater than 4 meters per second. Suitable for generating electricity.
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 the economic benefits.
Detailed information
A wind turbine is an electrical device that converts wind energy into mechanical work. Mechanical work causes the rotor to rotate and ultimately produces reciprocating output. current. Wind turbines consist oftypically consists 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 heat fluid. work.
For many centuries, wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy intended to replace human energyne and animal. 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. As a renewable and non-polluting natural energy source, wind energy has once again attracted attention.
