Advanced Control System for Wind Turbine

Variable speed drives in modern wind turbines are used to maximize wind turbine efficiency when the turbine is running below rated power and to reduce loading on the drive-train. In addition, there is something called a pitch control of the blades which is usually used to limit the energy captured when the turbine is operation above rated wind speed. The benefits of a more complex variable-speed drive, variable-pitch control of wind turbines is offset by control flexibility. That is, higher efficiency, better power quality, in addition to a longer useful life of the wind turbine.
