A method for identifying automatically an inner node within a hierarchical network causing an outage of a group of leaf nodes at the lowest hierarchical level, the method including providing an outage state matrix representing an outage state of leaf nodes at the lowest hierarchical level; decomposing the state matrix into a first probability matrix indicating for each inner node the probability that the inner node forms the origin of an outage at the lowest hierarchical level of the hierarchical network and into a second probability matrix indicating for each leaf node at the lowest hierarchical level of the hierarchical network the probability that an inner node forms a hierarchical superordinate node of the respective leaf node at the lowest hierarchical level of the hierarchical network and evaluating the first probability matrix to identify the inner node having caused the outage of the group of leaf nodes.
A method for identifying automatically an inner node within a hierarchical network causing an outage of a group of leaf nodes at a lowest hierarchical level of the hierarchical network, the method comprising the steps of:
An apparatus for identification of an inner node within a hierarchical network causing an outage state of a group of leaf nodes at a lowest hierarchical level of the hierarchical network, the apparatus comprising:
A network controller of a hierarchical power supply network, the network controller comprising a processing unit adapted to process an outage state matrix derived from event data streams received from smart meters of the hierarchical power supply network to identify automatically an inner node of the hierarchical power supply network having caused an outage of a group of leaf nodes of the hierarchical power supply network formed by smart meters.
