摘要： A method and system of configuring wind turbines is provided. The method and system includes generation of a plurality of configuration profiles. Thereafter, one of the configuration profiles is set as the active configuration profile and the rest of them are stored as shadow configuration profiles. Further, the performance of the active configuration profile and the shadow configuration profiles are monitored. Based on the performance of the configuration profiles, a candidate configuration profile is chosen. Further, a delta configuration profile is generated by eliminating the duplicate parameters from the candidate configuration profile and the active configuration profile. Further, the active configuration profile is updated with the delta configuration profile.

摘要： Systems and methods for controlling a wind turbine based on sensor readings are provided. A signal path between a sensor and a turbine controller can be modified and a secondary controller can be inserted between the turbine controller and the sensor. The secondary controller can receive a signal from the sensor and adjust the signal to an adjusted signal. The adjusted signal can be communicated to the turbine controller which can control operation of the wind turbine based at least in part on the adjusted signal. In this way, the operation of the wind turbine based on various sensor readings can be adjusted to provide for increased energy production without requiring access to computer-readable instructions, such as source code, implemented by the wind turbine controller.

摘要： A method is disclosed for calibrating a wind turbine sensor placed on a component of a wind turbine and where the wind turbine is of the type having a rotor with at least one pitchable wind turbine blade. The method comprises pitching one or more of the blades according to a predetermined pitch movement and detecting the response signal from the wind turbine sensor at least partly caused by the pitch movement. From this is then determined a characteristic sensor response value which upon comparison to a predetermined sensor calibration parameter forms the basis for a calibration of the wind turbine sensor if needed. The characteristic sensor response value may be determined from the pitch movement having been performed a number of times over a longer period of time.The invention further relates to a control system and a wind turbine configured for performing the method.

摘要： A wind of the type having a tower and a nacelle with a rotor rotatably connected to the nacelle for rotating about a rotor axis and having a plurality of equally spaced blades has the rotor balanced by firstly taking a measurement of torsional vibration and then by using photographic techniques to analyze dynamic imbalance caused by differences in the angle of attack of the blades. The torsional vibration is detected using two sensors at positions mirrored exactly in distance to the left and right of the rotor axis and detecting vibration in the axial direction. The angle of attack is measured by analyzing images of the tip of the blade where, during the analysis, distortion in angles at different locations in the image are corrected, in dependence upon a prior analysis of an image taken by the camera relative to a known image.
