How many kilowatt hours of electricity can be generated by wind power in one turn?

How many kilowatt hours of electricity can be generated by wind power in one turn?

It depends on the power of the wind turbine. If the power is large, the electricity production will be significant; if the power is small, the electricity production will be low. China's largest wind turbine is 2 MW, with daily electricity production equivalent to 11 tons of high-quality coal.

The generator turns 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 unit's capacity.

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 turbine spins about 18 times per minute.

This is related to factors such as fan type and capacity and generator speed.

For example, for a 2 MW direct drive wind turbine, its permanent magnet generator reaches the rated speed, for example 17 revolutions perminute, and it takes 60/17 = 3.5 seconds to complete one lap. If a 2 MW 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, or the amount of electricity generated in one revolution.

For dual-feed fans, this is also related to the gearbox reduction ratio.

No, let me tell you basically, the fan is 1500 kW. If it is full, it will spin at 17 revolutions per minute. If you do the math, one rotation equals 1.47 kilowatt hours of electricity. This is only an approximation and is not exact.

How much investment is required for 1 GW of offshore wind power? How much electricity can we produce on average each year? How much economic profit can it generate each year?

The process of converting installed wind energy capacity into wind generation capacityelectricity is as follows:

Electricity production capacity = installed wind energy capacity × wind turbine operating hours

Example: < /p>

A power plant wind turbine with an installed capacity of 200 MW has a total working hours of 2,000 hours per year, its electricity production capacity is therefore: 200 MW*2,000=400,000 MW. That is to say, the wind power plant can produce 400 million kWh of electricity per year.

The investment amount, power generation and economic benefits of offshore wind power projects will be affected by many factors, such as water depth of the location, speed wind, equipment selection, construction period, policy subsidies, etc. . Therefore, it is impossible to give a precise answer. The following provides only an approximate reference:

1. Investment amount: the investment amount for 1 GW of electricityOffshore wind energy typically exceeds billions of dollars. The specific investment amount depends on the project location, equipment selection, construction period and other factors.

2. Energy production: Offshore wind energy production is related to water depth, wind speed, wind energy density and other location factors. Usually, a 1 MW offshore wind turbine can generate around 25. -35 million kilowatt hours per year. Therefore, a 1 GW offshore wind power project can generate on average around 25 to 35 billion kilowatt hours per year.

3. Economic Benefits: The economic benefits of offshore wind power include energy revenues, policy subsidies, reduced carbon emissions and other factors. Generally speaking, the return on investment cycle takes several years to more than dix years, depending on the amount of project investment, political support, Factors such as electricity market prices.

It should be noted that the above data is for reference only, and the specific data should be evaluated according to the actual project conditions.
