Abstract: Controlling a wind turbine comprising a wind direction sensor, a yawing system, and a control system for turning the wind turbine rotor relative to the wind. Over one or more time intervals a data set comprising a direction of the wind relative to the wind turbine as measured by the wind direction sensor and a wind power parameter determined as one of a power, a torque, or a blade load of the wind turbine are obtained. The data sets are sorted into a number of bins of different intervals of wind power parameter. or each power bin, a statistical representation of the wind power parameter as a function of the relative wind direction is determined and then used in estimating a wind direction offset corresponding to the relative wind direction where the wind power parameter attains a peak value. The relative wind direction is then adjusted as a function of the set of wind direction offsets to yield more accurate wind direction data which can be used in controlling the turbine.

Abstract: A modular wind turbine blade is described. The modular wind turbine blade comprises first and second blade modules having spar caps embedded within their outer shells. The spar caps taper in thickness resulting in tapered recesses being defined in the outer shells. The tapered recesses in the first and second blade modules are aligned when the modules are placed end-to-end to form a continuous double-tapered channel. A connecting member having a double-tapered structure is bonded in the channel to connect the modules together. The invention also provides a mould for making the blade modules in which the mould surface includes a protruding elongate feature having a tapered portion configured to form the recesses in the outer shells. During layup and moulding of the outer shells, spar caps are supported on top of the tapered portion of the elongate feature.

Abstract: A tool chain (10) is provided for performing a method of removing internal components such as a bearing cassette (64) from the interior of a generator (12) and/or a gearbox (14) of a wind turbine. The tool chain (10) includes a tube (30) that extends through the interior of the generator (12), at least one clamp element (36) that concentrically fixes the tool chain (10) in position on at least one output shaft (60, 62) of the gearbox (14), and a sliding tool (50) that moves along the tube (30) into and out of the generator to couple with and pull out internal components to be repaired or replaced. For example, the tool chain (10) can remove the bearing cassette (64) located adjacent the junction of the gearbox (14) and the generator (12) without necessitating disassembly of the gearbox (14) from the generator (12).

Abstract: A set (200) of yaw claws (150) is provided comprising at least a first yaw (150a) claw and a second yaw claw (150b). The first yaw claw (150a) is to be used in a bearing ring (140) of a first yaw bearing (130) and the second yaw claw (150b) in a bearing ring (130) of a second yaw bearing (140). A circumference of the bearing ring (140) of the first yaw bearing (130) is substantially different from a circumference of the bearing ring (140) of the second yaw bearing (130). Each yaw claw (150) has a periphery, formed by a first side end (176), a second side end (178), an inner arc (172) and an outer arc (174), the inner arc (172) and the outer arc (174) being concentric with the respective bearing ring (140). At least two spring packs (166) are provided for pre-tensioning the yaw claw (150), respective spring pack centres (167) of the at least two spring packs (166) being arranged on a spring pack centreline (169) that is concentric with the inner arc (172) and the outer arc (174). A length of the spring pack centreline (169), measured from the first side end (176) to the second side end (178), of the first yaw claw (150a) is substantially equal to a length of the spring pack centreline (169) of the second yaw claw (150b).

Abstract: A modular wind turbine blade is described. The blade has at least a first blade module and a second blade module connected to end to end. An interface is defined between the respective modules. The blade further comprises at least one longitudinally extending spar structure that forms part of the outer shells of the first and second blade modules when the modules are connected. The or each spar structure is substantially continuous and extends across the interface between the first and second blade modules when the modules are connected. The or each spar structure is integrated with the first blade module and the spar structure is folded or coiled to facilitate transportation of the module. The second blade module includes channels defined in the outer shell for receiving the or each spar structure when the modules are connected. In this way the spar structures also form part of the outer shell of the second module. A method of assembling the modular blade and a method of installing a wind turbine having a modular blade are also described.

Abstract: Equipment for handling a wind turbine component includes a lifting cable and a mounting block having a block main body with a cable passage and a pair of bushings coupled to the mounting block. Each bushing has an aperture defined by an aperture wall and the lifting cable extends through the aperture of each of the bushings. At least an outer region of the aperture wall forms a closed loop about the lifting cable and is substantially circumferentially continuous. This allows the lifting cable extending the bushings to move in a circumferential direction along the aperture wall relative to the bushings during use. A method of assembling such handling equipment and a method of using such equipment for handling a wind turbine component is also disclosed.
