Abstract

Wind turbines have very specific characteristics and challenging operation conditions. Since they are designed and optimized to provide maximum power production for changing wind speeds and directions, they are expected to adapt to the rapidly varying physical conditions and other extreme environmental factors. Depending on their types and sizes, wind turbines are usually intended to be operational for wind speeds between 5 and 25 m/sec. In order reach this goal, most of the turbines utilize active pitch control mechanisms where the angle of the blade (pitch angle) is changed as a function of wind speed. Similarly, the whole rotor is rotated towards the effective wind direction by using the yaw mechanism.
