摘要： A wind turbine (100) including a control system and at least one wind turbine blade (108) having a pressure measurement system (200) is disclosed. The pressure measurement system (200) includes a pressure probe (300) that provides a measurement of inflow angle to the control system. The control system adjusts the blade pitch angle of the at least one turbine blade (108) in response to the inflow angle measurement to improve energy capture. The pressure probe (300) is mounted by a probe support structure (302) at a predetermined position from the leading edge (201) of the at least one wind turbine blade (108).

摘要： A blade insert (106) for coupling a first blade (20) segment to a second blade (22) segment is disclosed. The blade insert (106) may include an aerodynamic body (126) extending between a first end configured to be coupled to the first blade segment (20) and a second end configured to be coupled to the second blade segment (22). The aerodynamic body (126) may include a pressure side and a suction side extending between a leading edge and a trailing edge. In addition, the aerodynamic body may define a chord, wherein the chord at the first end is substantially equal to the chord at the second end.

摘要： The present subject matter relates to methods and systems for operating a wind turbine 600 that, in some embodiments may include a gearbox. The wind turbine 600 is provided with a blade 622 having an adjustable pitch angle and the tip speed ratio (TSR) of the blade is monitored. In operation, the method and system is configured to increase the pitch angle of the blade 622 concurrently with an increase in TSR to maintain turbine operation within an identified high power coefficient (Cp) operational region for the blade. TSR may be monitored by monitoring one of the velocity of the tip of the blade 622, wind speed, the rotational speed of the blade 622, or the rotational speed of a component within the gearbox.

摘要： A lift generating apparatus (300) for a wind turbine rotor blade (112) including a first sidewall (202,304,326) and an opposing second sidewall (206,306,328) coupled together at a leading edge (210,314,332,402,502,602,702) and at a trailing edge (212,312,334,404,504,604,704). The lift generating apparatus includes at least one forward blade extension (301,400,500) coupled to the rotor blade to define a first airflow channel (320) between the forward blade extension and the rotor blade, and at least one aft blade extension (302,600,700) coupled to the rotor blade to define a second airflow channel (342) between the aft blade extension and the rotor blade.
