What is a Pitch System?

A pitch system monitors and adjusts the angle of the wind turbine blades and thus controls the rotation speed of the rotor. At lower wind speeds, the ideal angle accelerates the rotor rotation speed, while at higher speeds, the blade pitch control reduces the wind load on the blades and structure of the wind turbine. Over a certain wind speed the pitch system starts to rotate the blades out of the wind, thereby slowing and stopping the rotor to avoid damage.
