The US Windpower 56--100 is a three-bladed, free yaw wind turbine, using full span blade pitch control for power regulation. It is theoretically possible to increase the energy capture of the 56--100 by adjusting the blade angle to the optimum pitch angle on a continuing basis at below rated speeds. This concept was field tested on the 56--100, but it was found that the optimum pitch control logic opens a pathway for the 56--100 to fall into stall operation when the winds are above the rated wind speed. The 56--100 then operates as a stall-regulated wind turbine with an overall reduction of energy capture and an increase in system loads.
