Abstract
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.
Claims20
A system for detecting faults in a power distribution network, comprising:
- a plurality of nodes;
- a concentrator device configured to transmit a signal to a plurality of nodes;
- at least one central processing device, to which the plurality of nodes are in communication, configured to:
- monitor the plurality of nodes and to detect that at least one node of the plurality of nodes received the signal;
- determine, based on the detection that at least one of the plurality of nodes received the signal, a first estimated probability that each node of the plurality of nodes is powered;
- generate a distribution map comprising the plurality of nodes and a plurality of transmission lines and which indicates, based on the first probability, whether each of the plurality of nodes is powered by assigning a first visual characteristic to each node of the plurality of nodes on the distribution map to indicate the first estimated probability that the corresponding node is powered;
- and,
- cause a user interface, comprising a display and at least one user interaction component, to display the distribution map to a human user,
- wherein the at least one user interaction component enables the human user to interact with the at least the power distribution network via the displayed distribution map.
