Embodiment Construction
[0077] figure 1 On the left a feed grid 1 for feeding electrical energy is shown schematically. The feeder network 1 is composed of three subsections 2 to 4 between which transformers 5 and 6 are connected. The spatially distributed power plants 7 to 11 feed the different regions 2 to 4 of the feeder network 1 . Measuring devices 12 and 13 detect grid parameters of feeder grid 1 in areas 3 and 4 . The transformers 5 and 6 , the power plants 7 to 11 and the measuring devices 12 and 13 are also collectively referred to here as units 5 to 13 . For clarity, figure 1 The electrical loads connected to the feeder network 1 are not shown in , although these are naturally present in practical situations. exist figure 1 The units 5 to 13 shown in are in communication with a gateway 14 and via the gateway 14 with system control units 15 to 18. Furthermore, identical or similar units can also be provided in or on feeder grid 1 , but are not shown here because they do not communicate...

The present application relates to a method of enabling a system control unit to communicate with a plurality of power generating devices. When the system control unit communicates with a plurality of power generating equipment distributed in space and commonly feeding electrical energy to the connected feeder network, the request data of the system control unit and the equipment data of the power generating equipment are received at a common gateway. In the gateway, the request data and device data are converted from different data models to metadata models. The transformed device data is managed in the gateway, and the transformed request data is managed, resulting in a data response to a specific system control unit (and / or to a specific power generation device) combined from the device data according to the metadata model The control command. The data response and / or control command is converted from the metadata model to the data model of the specific system control unit and / or power generation equipment in the gateway. The converted data response and / or control command is sent from the gateway to the specific system Control unit and / or power generation equipment.
Description
[0001] The application date of this application is November 10, 2014, the application number is 201480061429.X, and the title of the invention is "A method for making a system control unit communicate with multiple power generation equipment (formerly named "Used to enable a system control unit to communicate with a A method of communication between multiple generating units and a suitably configured and programmed data server")" is a divisional application of the application. technical field [0002] The invention relates to a method for communicating a system control unit with a plurality of spatially distributed power generating devices which together feed electrical energy into a connected feeder network. The invention relates in particular to a method having the following characteristics: a method for communicating a system control unit with a plurality of spatially distributed power generating devices that collectively feed electrical energy into a connected feeder networ...
