摘要:
A rotor blade assembly having an access window and methods for assembling a rotor blade are disclosed. The rotor blade assembly may generally include a first shell component and a second shell component. The first shell component may be secured to the second shell component. Additionally, an access region may be defined in the first shell component and/or the second shell component. The access region may generally be configured such that an access window is defined in the rotor blade assembly. The access window may be configured to provide access to the interior of a portion of the rotor blade assembly.
摘要:
A wind turbine includes a plurality of wind turbine blades attached to a rotor positioned atop a tower affixed to a tower foundation. At least one blade pitch sensor is configured to measure blade pitch angles for one or more of the wind turbine blades. A rotor/generator speed sensor is configured to measure the rotational speed of the wind turbine rotor, a corresponding wind turbine generator, or both. A wind turbine nacelle yaw sensor is configured to measure the nacelle yaw, while at least two tower-base bending sensors are configured without use of adhesives, cements or bonding agents to provide large-area measurement of tower deflection. A controller is configured to adjust the pitch angle of one or more of the wind turbine blades in response to the measured one or more blade pitch angles, the measured rotational speed, the measured nacelle yaw and measured tower longitudinal deflection.
摘要:
A method of assembling a wind turbine blade comprises providing a first blade segment comprising at least two first spar cap segments; providing a second blade segment comprising at least two second spar cap segments; inserting the second blade segment into the first blade segment wherein a spar cap cavity is formed between each set of corresponding first and second spar cap segments; injecting an adhesive into the spar cap cavities to bond the blade segments together, wherein a scarf joint is formed between each set of corresponding first and second spar cap segments.
摘要:
A joint for connecting a first blade segment and a second blade segment of a wind turbine rotor blade is disclosed. The joint includes a body, the body including an outer surface and an inner surface. The outer surface has an aerodynamic contour that generally corresponds to an aerodynamic contour of the first blade segment and the second blade segment. The body includes a pressure side and a suction side extending between a leading edge and a trailing edge. In some embodiments, the joint further includes a channel defined in the outer surface of the body. The channel includes a generally continuous base wall extending between opposing sidewalls. The inner surface includes the base wall. In other embodiments, the joint further includes a channel defined in the body, and a shell extending from the body in a generally span-wise direction.
