Abstract: A method and arrangement to produce a wind-turbine-blade are disclosed. A bottom layer is laid down into a forming tool. The bottom layer is used as a base of a pile. A predefined number of additional layers is stacked vertically on top of the basis to form the pile, while the pile is used as a separate module for the production of the blade. The bottom layer is made of a nearly airtight material, to prevent that surrounding air is allowed to flow vertically through the pile. An extraction of air is applied by a machine to a topmost layer of the pile in a way that the pile is sucked towards the machine. This allows to lift up the pile and to bring it into a mould for the further production of the blade.

Abstract: The present invention provides a power converter that can be used to interface a generator (4) that provides variable voltage at variable frequency to a supply network operating at nominally fixed voltage and nominally fixed frequency and including features that allow the power converter to remain connected to the supply network and retain control during supply network fault and transient conditions. The power converter includes a generator bridge (10) electrically connected to the stator of the generator (4) and a network bridge (14). A dc link (12) is connected between the generator bridge (10) and the network bridge (14). A filter (16) having network terminals is connected between the network bridge (14) and the supply network. A first controller (18) is provided for controlling the operation of the semiconductor power switching devices of the generator bridge (14). Similarly, a second controller (46) is provided for controlling the operation of the semiconductor power switching devices of the network bridge (14). The first controller (18) uses a dc link voltage demand signal (VDC_GEN*) indicative of a desired dc link voltage to control the semiconductor power switching devices of the network bridge (10) to achieve the desired level of dc link voltage that corresponds to the dc link voltage demand signal (VDC_GEN*). The second controller (46) uses a power demand signal (P*) indicative of the level of power to be transferred from the dc link to the supply network through the network bridge (14), and a voltage demand signal (VTURB*) indicative of the voltage to be achieved at the network terminals of the filter (16) to control the semiconductor power switching devices of the network bridge (14) to achieve the desired levels of power and voltage that correspond to the power and voltage demand signals (P* and VTURB*).

Abstract: A method and an arrangement for a forecast of wind-resources of a wind-farm are provided. The forecast is done by a numerical weather-prediction-tool, the weather-prediction-tool using a long-term data-set of meteorological data. The data are related to the location of the wind-farm. A wind-speed measurement is done by a wind-turbine of the wind-farm to do a parameterization of an atmospheric turbulence. The wind-speed measurement is used to generate a data-stream, which is combined with the data-set of the meteorological data to do the forecast.

Abstract: A method and a wind power plant are provided for smoothing alternating electric current from a number of power generators. Generators are electrically connected to an electric network. Each power generator includes a transformer with pulse width modulation for converting direct current to pulse width modulated alternating current for feeding to the network. The time for feeding the pulses of the pulse width modulated alternating current is different for each generator in order to achieve a more even alternating current as a sum of respective outputs of alternating current from the generators.
