Technical Specifications of Wind Turbines
Some Technical Specifications of Wind Turbines: 
Rated power is the maximum power that can be safely produced at the given range of wind speed by a wind turbine. For example, the rated power of 4000 kW at the range of 13-23 m/s wind speed. 
The number of blades - horizontal axis three-bladed wind turbines are the most common. 
Horizontal-axis rotors are upwind or downwind. For example, an upwind rotor with a clockwise rotation. 
Wind turbine generators are synchronous or asynchronous. Synchronous generators are best suited with direct drive gearless systems and asynchronous generators with gears. 
The Yaw system is a mechanism that allows turning a rotor in the upwind direction. 
The power curve of a wind turbine is a curve that demonstrates power production and power coefficients at a specific range of wind speed.
