POWER GRID TOPOLOGY DISCOVERY VIA TIME CORRELATION OF PASSIVE MEASUREMENT EVENTS

摘要

A wireless mesh network is configured to manage a power grid. Each node within the wireless mesh network is configured to detect and classify voltage fluctuations in power supplied by an upstream transformer coupled to the power grid. When a given node detects a particular type of fluctuation (i.e., an “event”), the node generates a timestamped event classification that reflects the type of event and a time when the event occurred. A server configured to manage the wireless mesh network receives timestamped event classifications from each node within the wireless mesh network and then performs a time correlation with the received timestamped event classifications to determine which nodes detected similar events. When two or more nodes detected the same event at similar times, the server determines that those nodes are coupled to the same transformer.

1. A computer-implemented method for determining a topology of a power grid, the method comprising:
receiving a first timestamped event classification from a first node residing within a network of nodes; receiving a second timestamped event classification from a second node residing within the network of nodes; determining, via a processor, that the first timestamped event classification is correlated with the second timestamped event classification; and determining that the first node and the second node are both coupled to a particular device within the power grid based on the first timestamped event classification being correlated with the second timestamped event classification.
