DISTRIBUTION CONTROLLER AND A METHOD FOR IDENTIFYING AN ORPHAN NETWORK AND TRANSMITTING A STANDARDIZED DESCRIPTION OF THE ORPHAN NETWORK TO ANOTHER DISTRIBUTION CONTROLLER

摘要

The present invention is concerned with a distribution controller (19) for controlling a distribution of electrical power in an assigned first power distribution region (1). The controller is adapted to be connected to process devices (21) which in turn interact with primary devices (5, 7, 9, 11, 13) of the assigned first region. The distribution controller is provided with a standardized, machine-readable network description of the first region and comprises means to identify, following a network reconfiguration, the extent of an orphan network section (23) that is no longer connected to the first region. The distribution controller is further adapted to transmit a description of the orphan network section to a second distribution controller (19') controlling a second or neighbouring power distribution region (1') to which the orphan section has been connected as a consequence of the network reconfiguration. Due to this capability of transmitting descriptions of the network section changing hands, there is no need to keep and update a description of the entire network in each controller of the power distribution system.
