Non-technical loss detection and localization

摘要

Embodiments of the present invention provide a system, method, and computer program product to detect and localize non-technical losses in an energy distribution system. A computing device determines the energy consumption of a link and/or node that is associated with an energy grid. The computing device determines the mismatch between the determined energy consumption of the link and/or node and the predicted energy consumption of the link and/or node. The computing device also determines the location of unauthorized energy consumption within the energy that is associated with the mismatch.

主权项

1. A method comprising:
estimating, by a supervisory control and data acquisition (SCADA) system located at a rood node, an estimated electrical energy consumption value for a predetermined time interval; measuring, by the SCADA system, an actual electrical energy consumption value corresponding to electrical energy supplied by the root node of a grid during the predetermined time interval; determining, by a computing device, that a mismatch between the estimated electrical energy consumption value and the actual electrical energy consumption value exceeds a technical loss threshold such that non-technical losses were experienced by the grid during the predetermined time interval; receiving, from a plurality of smart meters respectively located at a plurality of energy consumption nodes, over a communication network and by the computing device, a plurality of voltage values collected during the predetermined time interval, with the plurality of voltage values indicating voltage levels experienced at the respectively corresponding smart meters; and responsive to the determination that non-technical losses were experienced by the grid, determining, by the computing device, a location the non-technical losses based on the voltage values collected from the plurality of smart meters.
