Abstract
A power line configuration or topology may be determined by identifying metering nodes that have time-stamped voltage values that correlate with voltage values measured at a transformer or other metering nodes at substantially the same time. A correlation between the time-stamped voltage values may be calculated by, in some examples, comparing a difference of a first time-stamped voltage value of a meter and a second time-stamped voltage value of a transformer or the second metering node to a predetermined threshold. If the difference is below the threshold, the metering node may be determined to be connected to the transformer or second metering node by a power distribution line.
Claims22
A method comprising:
- receiving a first voltage value measured at a metering node of a power distribution system;
- receiving a second voltage value measured at a transformer of the power distribution system;
- calculating a correlation between the first voltage value and the second voltage value;
- and
- determining if the metering node is connected to the transformer by a power distribution line, based at least in part on the correlation.
A method comprising:
- receiving a plurality of time-stamped voltage values, each of the time-stamped voltage values corresponding to one of a plurality of metering nodes or one of a plurality of transformers;
- storing the plurality of time-stamped voltage values in a memory;
- calculating, for a subset of the plurality of time-stamped voltage values that share a common time-stamp, a correlation;
- and
- determining which of each of the plurality of metering nodes are connected to which of each of the plurality of transformers by a power distribution line, based at least in part on the correlation.
A system comprising:
- a processing unit configured to perform operations comprising:
- receiving a first voltage value associated with a first device;
- receiving first location information associated with the first device;
- receiving a second voltage value associated with a second device;
- receiving second location information associated with the second device;
- calculating a correlation between the first and second voltages;
- determining connection information of the first device to second device based at least in part on the correlation;
- and
- displaying the connection information on a map, the map showing the first device at a first location corresponding to the first location information and the second device at a second location corresponding to the second location information.
