How do you understand the phrase “a 3 MW wind turbine”?

That is, the rated power is 3 MW and it can generate 3,000 kWh of electricity per hour. Generally, to achieve the rated power, a rated wind speed (approximately 15 meters/second) is required.

The fan works between the input wind speed and the cut-off wind speed, which is about 3.5m/s ~ 25m/s: it cannot rotate when the wind is weak and it cannot work. if the wind is too strong and dangerous (so it must be stopped when a typhoon arrives).
