摘要： According to an embodiment, the method is for operating a wind turbine having a rotor with at least one rotor blade and a setting system which is configured to change the operation of the wind turbine. The method includes a step in which first trigger information is provided, wherein the first trigger information is representative of whether the torsional movement of at least one rotor blade exceeds a threshold. If this is the case, a first output signal is generated which is configured to cause the setting system to change the operation of the wind turbine in order to reduce the torsional movement of the at least one rotor blade.

摘要： This disclosure is directed to a method for operating a wind turbine which includes a speed-variable drive system. The system includes an electrical machine and a pulsewidth modulation-controlled converter. The speed-variable drive system is connected to an electrical grid. In the event of a transient grid fault, a frequency of the pulsewidth modulation is determined in response to a current in an electrical circuit connected to the converter.

摘要： A method is for controlling the quality of a wind turbine rotor blade. The method includes: manufacturing of a wind turbine rotor blade at a manufacturing site, placing the wind turbine rotor blade on a support at the manufacturing site, applying a dynamic load to the wind turbine rotor blade while the wind turbine rotor blade is placed on the support in order to excite a vibration of the wind turbine rotor blade, detecting the vibration of the wind turbine rotor blade, determining an eigenfrequency of the wind turbine rotor blade based on the detected vibration, comparing the determined eigenfrequency with an expected eigenfrequency of the wind turbine rotor blade and evaluating the quality of the wind turbine rotor blade based on the results of the comparison.

摘要： A wind turbine rotor blade having a first rotor blade segment with a first connection end and a second rotor blade segment with a second connection end assigned to the first end. The first segment has first mounting sleeves at the first end. The first mounting sleeves each have a first internal thread. The second rotor blade segment has second mounting sleeves at the second connection end. Each of the second sleeves define a longitudinal axis and has a second internal thread arranged therein. Each of the second internal threads is displaceable axially with respect to the corresponding longitudinal axes. The rotor blade further has a plurality of connecting bolts threadably engaging a pair of first and second sleeves via corresponding internal threads such that the first segment and the second segment are mechanically interconnected at the first end and the second end.

摘要： A rotor bearing housing for a wind turbine has: a bearing body for receiving a rotor shaft of the wind turbine, a support body arranged under the bearing body and configured to be coupled at a first end to a base element in order to transmit a force flow between the bearing body and the base element. The base element is arrangeable under the support body for the purposes of rotatable fastening to a first end of a tower of the wind turbine, the bearing body and the support body together forming a single-piece body, and the bearing body and the support body being configured such that, if a geometrical central point of the first receptacle for a rotor bearing is projected onto a cross-sectional plane of the first end of the tower, the geometrical central point is arranged outside a diameter of the tower at the first end.
