The largest is 5 MW in Denmark and one in China. Generally, 2 MW, 1.5 MW or less 0.8 MW are used in China.
The common models currently used in wind farms are all 1.5 MW units, that is, the full power of the wind turbine is 1,500 kW. This 1500 is the power output. It is not necessary to calculate the power factor. But now wind turbines all have some breeder generation capabilities, and some models can even generate up to 1,700 KW. However, given the particularity of wind farms;
The power changes quickly depending on the changes in the wind, therefore. full power is not often the case. Current wind farm planning generally calculates that a phase does not exceed 50 MW, so a single 1.5 MW wind turbine with 33 units has a total power of 49.5 MW.

In a pure resistance circuit, according to Ohm's law U=IR and substituted by P=UI, we can also obtain: P=I2R =(U2)/ R
In dynamics: power calculation formula: 1.P=W/t (average power) 2. P=FV P=Fvcosα (instantaneous power)
Because W =F (force F) × S (displacement s) (the definition of work), the power formula can also be derived under the form P=F v:
P=W /t=F* S/t= F*V (this formula is suitable for objects moving in a straight line at a uniform speed)P in the formula represents power, the unit is "Watt", called "Watt", and the symbol is W.
W represents work. The unit is "joule", called "joule", and the symbol is J.
t represents time, the unit is "second" and the symbol is "s".

Normally this is around 690 volts.
Small wind turbines frefer to wind turbines with a generator capacity of 0.1 to 1 kW.
Mid-sized wind turbines refer to wind turbines with a generator capacity of 1 to 100 kW.
Large wind turbines refer to wind turbines with a generator capacity of 100 to 1,000 kW.

Development prospects
Usually, people think, the wind power generation power is entirely determined by the power of the wind turbine. I always want to buy a bigger wind turbine, but that's incorrect.
The current wind turbine only charges the battery, and the battery stores electrical energy. The amount of electrical energy people ultimately use is most closely related to the size of the battery. The size of the power mainly depends on the size of the air volume, not just the machine head. The amount of power. On the contiHowever, small wind turbines are more suitable than larger ones.
Because they are more easily driven by small winds to produce electricity, small continuous winds can provide more energy than temporary strong winds. When there is no wind, people can still use the electricity brought by the wind normally. In other words, a 200W wind turbine can also be used with a large battery and an inverter to achieve 500W or even 1000W or more power. .
