That is, the rated power is 3MW and it can generate 3,000 kilowatt-hours of electricity per hour. Generally, to reach the rated power, a rated wind speed (about 15 meters/second) is required.
The fan operates between the cut-in wind speed and the cut-out wind speed, which is about 3.5m/s~25m/s: it cannot rotate when the wind is small, and it cannot operate if the wind is too high and dangerous (so It must be shut down when a typhoon comes).
The maximum power of a single wind power generation unit is 5MW. According to relevant public information, the world's largest wind turbine has an output power of 5MW. It has three rotors, each of which is 61.5m long. The diameter of the rotor area is 126m. The highest point is 183m above the ground. It will be installed on the Elbe River in Germany. estuary.
