This depends on several factors
1. Configuration of the windmill
2. Wind conditions
For example, if the diameter is 60 meters, the wind speed is above 38 kilometers per hour. , the power generation capacity can also reach 2000 kilowatts
Generally speaking, level 3 wind is valuable for utilization. However, from an economic and reasonable perspective, wind speeds greater than 4 meters per second are suitable for power generation. 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; when the wind speed is 6 meters per second, Only 16 kilowatts; and 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.
As mentioned in the answer, only when the wind speed is greater than 4 meters/second can it have the value of generating electricity
The name of wind power is equivalent to the wind speed and wave height at 10 meters on the open flat ground. Onshore physics Symptoms
