摘要： The invention relates to a method to regulate the output power production of a wind turbine with respect to the market price of the electricity and with respect to the life time of components of the wind turbine. According to the method invented the output power production of a wind turbine is regulated. A wind speed is estimated for the wind turbine based on local meteorological data, which are allocated to the wind turbine site. A load, which acts on at least one component of the wind turbine, is estimated based on the estimated wind speed. A lifetime consumption of the component is estimated based on the estimated load. The output power of the wind turbine is estimated based on the estimated wind speed. A reference value is calculated, which takes into account the market price of the estimated output power and the estimated lifetime consumption. Settings of the wind turbine are adjusted to increase or to decrease the output power production of the wind turbine based on the reference value.

摘要： The present invention relates to a method for monitoring blade frequencies of a wind turbine and a monitoring system for performing the method. By the invention an accelerometer or G-sensor is placed into the nacelle of a wind turbine and thereby measuring the vibrations of the nacelle. To extract the vibration signals originating from each blade, the vibration signals are combined with the measuring signals from the azimuth angle sensor (rotating angle), which is normally used for pitch control. To further extract each blade frequency a Fast Fourier Transformation (FFT) is used on the modulated G-sensor signals. To further monitor a severe and alarming change in each blade frequency each blade frequency is compared to the other blade frequencies and an alarm is set if a given level is reached.

摘要： The invention relates to a method for computer-assisted determination of the usage of electrical energy produced by a power generation plant, particularly a renewable power generation plant. The method uses a plurality of neural networks (NN1, NN2) 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 (NN1, NN2) are used to build histograms. Based on those 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. Particularly, energy amounts having a higher likelihood of availability in the future are sold at higher prices than other energy amounts. The method of the invention is preferably used for renewable power generation plants for which the energy output is fluctuating according to environmental conditions. E.g., the invention may be used for a wind power generation plant or a solar power generation plant.
