Abstract: An arrangement for determining a rotational-speed of a blade rotating around an axis is provided. A transmit-unit is located at the rotating blade, while a receive-unit is located at the rotating hub of the blade. The transmit-unit and the receive-unit are connected by a transmission-system, which is used to transmit a signal from the transmit-unit to the receive-unit. A detection-unit is located at the blade, which is used to detect a force acting on the blade due to the rotation of the blade. The detection-unit is built to interrupt the transmission of the signal when the detected force exceeds a predetermined value. The receive-unit comprises a control-unit, which detects a high rotational-speed of the blade by evaluating the interrupted transmission of the signal. The transmission-system is built as an optical-transmission system, which transmits an optical-signal from the transmit-unit to the receive-unit for evaluation.

Abstract: In one aspect, a method for the determination of a nacelle-inclination is provided. A first difference-signal is formed from the difference of a measured nacelle acceleration and an offset-value from a calibration. A second difference-signal is formed from a difference of the first difference-signal and a feedback signal. A first sum-signal is formed from adding an integrated second difference-signal with the product of the second difference signal and a factor. A second sum signal is formed from adding an integrated first sum-signal with the product of the first-sum-signal and the factor. A corrected signal is formed by a product of the second sum-signal and an equivalent tower height. A first nacelle-signal is formed by the arc-tangent of the corrected signal. A nacelle inclination is obtained from filtering the first nacelle-signal by a low-pass-filter. The feedback-signal is formed by multiplying the acceleration of gravity with the sine of the first nacelle-signal.

Abstract: A method for computer-assisted determination of usage of electrical energy produced by a power generation plant such as a renewable power generation plant is provided. The method uses a plurality of neural networks having a different structure or being learned differently for calculating future energy amounts produced by a power generation plant. To do so, the energy outputs of the power generation plant forecasted by the plurality of the neural networks are used to build histograms. Based on the histograms, energy amounts for different confidence levels describing the likelihood of the availability of the energy amount are determined, and different uses are assigned to different energy amounts. Energy amounts having a higher likelihood of availability in the future are sold at higher prices than other energy amounts.
