Abstract

AES conducted a conceptual study of independent pitch control using inflow angle sensors. The control strategy combined input from turbine states (rotor speed, rotor azimuth, each blade pitch) with inflow angle measurements (each blade angle of attack at station 11 of 15) to derive blade pitch demand sugnals. The controller reduced loads suffficiently to allow a 10% rotor extension and reduce COEby 6.3%.
