Abstract
Power grid surveillance via topology detection system using power line communications (PLC) is provided by observing, at first and second times, first and second signals, respectively, sent via PLC between a plurality of nodes in an electrical grid; generating first and second lists for a given node of the plurality of nodes of channel impulses responses (CIRs) for the given node to communicate with other nodes in the plurality of nodes respectively based on the first and second signals as observed; identifying from the first list and the second list a certain node with a highest variation in CIR between the first time and the second time; sending a first token for the given node from the given node to the certain node via PLC; and in response receiving a second token from the certain node at the given node, generating a topology change alert.
