The wind is different every day, so wind energy does not need to produce electricity every day to evaluate the energy production of a wind farm or wind turbine. Generally, statistical methods are used to estimate the average number of full load hours per kilowatt of installed capacity per year (including four seasons). In other words, if a 1,500 kW wind turbine generates 3 million kWh of electricity per year, then 3,000,000/1,500 = 2,000 hours, then the full load hours of this wind turbine at this location are 2,000 hours. A 50,000 kW wind farm generates 110 million kilowatt hours of electricity per year, or 110,000,000/50,000 = 2,200. The full load hours of this wind farm are 2,200 hours. Generally speaking, the annual full load hours of relatively good wind farms can reach 2,400 to 2,500 hours (corresponding to an annual average wind speed of more than 7 m/s), and the ergeneral res can reach 2,200 hours (corresponding to the average annual wind speed). speed of 6.8-7 m/s). Under normal circumstances, wind speeds below 2,000 hours will not develop at this time (corresponding to an annual average wind speed below 6.4). The longer the blades of the wind turbine, the greater the wind energy absorbed, but the lower the wind resistance capacity, so the length of the blades of the wind turbine should be selected according to different wind conditions. local wind. Let's just say this to start. The detailed study of wind energy production is increasingly rich in content.
The voltage generated by current wind turbines is generally 690V. Transformed into 10kV or 35kV, transmitted to the substation then boosted to 110kV (or 220kV, rarely).
How much energy can a small 100W wind turbine generate per day with a speed ofwind of two meters per second?
People who answered 2.4 million degrees did not read the question carefully.
What is the concept of a 100 KW wind turbine that generates 2.4 million kilowatt hours per day? I have to spend all my money to build such a 100KW wind turbine if I connect at 0.5 yuan per unit. , I can earn 1.2 million per day.
Not to mention that it is impossible for a wind turbine to operate at rated wind speed only for 24 hours a day. Even if it is 24 hours a day, the electricity that can be generated that day is only 100 kW. *24h=2400kwh, 2400 degrees.
Generally, a day's electricity production can only be estimated based on the average rated wind speed for 7 hours, i.e. 100 kW x 7 h = 700 kWh.
If your wind turbine is windy all day and operates at full speed 24 hours a day, the maximum energy production per dayis 2.4 kWh. Since the amount of electricity produced by wind turbines is affected by factors such as wind speed and strength, the amount of electricity produced is not fixed. When the wind is strong, more electricity will be produced, and when the wind is light, the amount of electricity produced is affected by factors such as wind speed and strength. electricity will be less.
