Abstract: A method for detecting islanding conditions in a low voltage (LV) electric power network, wherein the electrical power network comprises a plurality of sub-networks. The sub-networks comprise at least one power electrical unit and are separable from each other and a main grid supplying the network by switching devices. The method comprises determining topological information of at least one sub-network of interest, detecting islanding conditions in at least one sub-network of interest on the basis of the topological information by using separate detecting means for each sub-network of interest, and sending, on the basis of the islanding conditions detected by using the detecting means, a disconnect signal to at least one power electrical unit in at least one sub-network of interest.

Abstract: 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 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 controlling a second or neighbouring power distribution region to which the orphan section has been connected as a consequence of the network reconfiguration. Due to this capablility 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.
