FRAMEWORK FOR FAULT DETECTION AND LOCALIZATION IN POWER DISTRIBUTION NETWORKS

摘要

Systems and methods for detecting faults in a power distribution network are described. In an aspect, the systems and methods determine a probability that each node of the network is powered and a probability that each distribution line in the network is faulted. In another aspect, the systems and methods determine the probabilities by transmitting a signal over a power distribution network with an active sounding system. In an additional aspect, the systems and methods determine the probabilities by utilizing collected data coupled to the power distribution network.

1. A system for detecting faults in a power distribution network, comprising:
one or more sensing devices coupled to the power distribution network, the sensing devices receiving data from the power distribution network, and the power distribution network comprising a plurality of nodes; a memory device coupled to the one or more sensing devices comprising a data management module, the data management module storing the received data from the one or more sensing devices; a processing device comprising a processor, coupled to the memory device, the processing device comprising processor executable instructions for:
determining, based on the received data, a first estimated probability that each node of the plurality of nodes of the power distribution network is powered;determining, based on the received data, a second estimated probability that each transmission line of a plurality of transmission lines connecting the plurality of nodes is faulted;generating a distribution map comprising the plurality of nodes and the plurality of transmission lines for display;assigning a first visual characteristic to each node of the plurality of nodes based on the first estimated probability for the corresponding node; andassigning a second visual characteristic to each transmission line of the plurality of transmission lines based on the second estimated probability for the corresponding transmission line.
