Abstract:
A control system and a method for controlling operation of a wind turbine are disclosed. A first sensor and a second sensor are arranged for sampling or continuously measuring a first physical value and a second physical value being representative of a first physical impact and a second physical impact on components of the wind turbine in order to provide a first and a second control parameter for controlling operation of the wind turbine. The first and second control parameters are distinct. During active generation of energy the control system is adapted to selectively switch between controlling the operation of the wind turbine either on the basis of the first control parameter or on the basis of the second control parameter, i.e. to selectively switch between two different, distinct and independent control strategies. The two control strategies allow redundancy in control of the operation of the wind turbine. Both control strategies are based on measurements of actual physical impacts affecting the components of the wind turbine, thereby making it possible to control the wind turbine in a more optimal manner than when using prior art control systems and methods, regardless of which control strategy is selected.
Abstract:
The invention relates to a docking module for a test stand for testing of wind turbine components. The docking module has standardized electrical, mechanical and data communication connections so that the docking module comprising a wind turbine component to be tested may be connected to and disconnected from the test stand quickly. If two or more such docking modules are available, mounting of a wind turbine component to be tested inside a docking module may be performed while the test stand is operating in testing another wind turbine component. Hereby, the overall operating time of the test stand may be maximized in that the time for changing the wind turbine components to be tested is minimized.
Abstract:
A control system for controlling operation of a wind turbine, a wind turbine having such a control system and a method for controlling a wind turbine are disclosed. The control system comprise s a first sensor device and a second sensor device, each being arranged for measuring the same control parameter used for controlling operation of the wind turbine. The first sensor device has a first set of operating failure conditions, and the second sensor device has a second set of operating failure conditions. The first set of operating failure conditions comprises at least one operating failure condition which does not form part of the second set of operating failure conditions. The system further comprises a third sensor device for detecti ng an operating failure condition of the first sensor device and/or of the second sensor device. The control system is adapted to select between controlling operation of the wind turbine on the basis of control parameters measured by the first sensor device or on the basis of control parameters measured by the second sensor device, based on measurements performed by means of the third sensor device. Thereby a redundant system for measuring the control parameter is obtained, allowing reliable measurements of the control parameter, even under conditions where the first sensor device fails.
Abstract:
The present invention relates to an acoustic noise monitoring system for a wind turbine, comprising: a microphone for monitoring acoustic noise, the microphone adapted to be mounted to the exterior of a wind turbine nacelle; an input, the input adapted to receive operating conditions data from a wind turbine; a processor, the processor adapted to receive data from the microphone and the input; and storage memory, adapted to store the acoustic noise data and the operating conditions data. The processor is adapted to apply a transfer function to said acoustic noise data to correlate said data with a set of acoustic noise data measured at a remote location from the wind turbine. The system may comprise a controller adapted to generate a control signal, for outputting to a wind turbine controller, for adjusting the operating parameters of the wind turbine in dependence on said correlated data.
Abstract:
A new method is proposed for determining a Nacelle Transfer Function (NTF), in which an individual NTF is provided for each wind turbine compensating for both structural effects, those that arise from the shape and configuration of the wind turbine, and environmental effects, those that are a result of the terrain or geographical location. Based on the assumption that the turbine is running correctly and SCADA data is taken over a certain period, and based on a siting model to give data on Turbulence Intensity (TI), υpflow, shear and other atmospheric parameters (as a function of wind speed and wind direction as necessary) the NTF can be determined from a site specific power curve made generated using a computer model. The NTF is the function that gives the required site power curve over the period that data is available. Unlike, previous techniques, there is no requirement to use a met mast.

Abstract:
A method for real-time prediction of wind conditions across a wind farm (1) comprising a plurality of wind turbines (1), the wind farm (1) being arranged at a wind farm site, is disclosed. A first library (9) of site specific mean wind flow patterns related to the wind farm site, and a second library (10) of non-site specific turbulence patterns, are provided. Weather data is measured at a plurality of positions within the wind farm site, and based on the measured weather data, a mean wind flow pattern is selected based on the first library (9) and a turbulence pattern is selected based on the second library (10). A site specific wind flow field across the wind farm site is modelled, based on the selected mean wind flow pattern and the selected turbulence pattern, and wind conditions across the wind farm (1) are predicted, based on the site specific wind flow field.
