Abstract: A method is provided for operating an electric energy production facility during a fault in a utility grid to which energy is to be delivered. The energy production facility includes at least one wind turbine. The method includes disconnecting the utility grid from the wind turbine. The method further includes connecting an external generator via a cable to an auxiliary equipment of the wind turbine, to deliver active power to the auxiliary equipment. The cable is connected to a converter of the wind turbine the converter supporting reactive power. A corresponding arrangement also provided.

Abstract: Method of transmission of data between at least two communication devices which are connected together over a data network. The communication devices are respectively connected to a coding device and the sent data are source- and channel-coded by a coding method respectively furnished within the coding devices. The data are converted within a converting device connected to the data network.

Abstract: A method and circuit arrangement for connecting ATM communication equipment to an ATM trunk group, where characteristic parameters reported for virtual connections to be set up are allocated to connection classes and to transmission classes corresponding to the connection classes. The parameters are defined for the individual lines of the ATM trunk group. Further, line particulars with respect to all of the transmission classes for which a virtual connection can still be set up, based on currently available free transmission capacity, are individually retained for the associated individual ATM trunks. When a request for setting up a virtual connection is present, an individual trunk for setting up the virtual connection is selected during the course of a search event involving the line particulars of all individual trunks. A transmission class that corresponds to the connection class to be considered in the virtual connection to be set up is determined from the line particulars of the individual trunk.
