Abstract: A method for outputting control instructions to at least one first wind power installation or at least one first wind farm using an evaluation device or for outputting an event message relating to an operating state of the at least one first wind power installation or the at least one first wind farm using the evaluation device is provided. Data is received by the evaluation device from at least one further wind power installation or from at least one further wind farm and the control instructions or the event messages are generated by evaluating the data and are output by the evaluation device. An evaluation device and a system having the evaluation device for carrying out the method are also provided.

Abstract: A method for authorizing a user for a control access to at least one wind turbine or at least one wind farm is disclosed. In this method, a certification center first authenticates a user, and the certification center accepts a control-access type from the authenticated user. The certification center then generates an electronic certificate according to the accepted control-access type and/or according to stored access permissions of the authenticated user. Then the certificate is used for authentication with the wind turbine or with the wind farm for the purpose of performing a control access. A system for performing the method and also relates to a certification center and to an interface of a wind turbine or of a wind farm.

Abstract: A method for transmitting data records of a plurality of wind turbines or and a plurality of windfarms to a control center as well as a wind turbine, control center and a system configured to perform the method are disclosed. The method includes dispatching a notification of an updated data record from one of the wind turbines or windfarms to the control center. A decision is then made in the control center as to whether the updated data record is to be requested. A request for the updated data record is dispatched from the control center to the wind turbine or windfarm only if the updated data record is to be requested. The request is received in the windfarm or wind turbine and a reply with the updated data record reply is sent to the control center.

Abstract: A method and an apparatus for presenting measurement data from a plurality of sensors of a physical wind power installation or its components on a display is provided. At least one view of an image of a wind power installation and/or of at least one component of the wind power installation and of a plurality of interaction elements is presented together with the view. At least one sensor of the wind power installation or of the component respectively assigned to each interaction element a controller. The measured values made by the sensor(s) can be retrieved via the assigned interaction element. In addition, each interaction element is respectively arranged in substantially the same position in the view as a position at which the at least one sensor assigned to the respective interaction element is arranged in the physical wind power installation or its component.

Abstract: A method for graphically presenting sensor data from wind power installations is provided. A data interface of an apparatus receives sensor data from wind power installations and/or wind farms connected to the data interface. A memory stores the received sensor data. An input interface is used to select at least one current time or part time. Furthermore, a display interface is used to output signals for the purpose of presenting geographical maps and sensor values using a display. A plurality of sensor data or all sensor data for the selected time are retrieved from the memory, and the display interface outputs display signals to present the retrieved sensor signals with a map substantially at a position at which the wind power installation from which the respective sensor data were received is positioned. An apparatus for carrying out the method and a system having the apparatus are provided.
