Abstract: Systems and methods to determine an event location on a feeder line segment that is downstream of a feeder line branch. A first indication of an event is received from a sensor located on a feeder line upstream of the feeder line branch. A status of a monitored segment downstream of the feeder line branch is determined based on receiving the indication. The monitored segment is determined to be a particular branch based on locations of the feeder line branch, status sensors downstream of the feeder line branch, and location data of segments downstream of the feeder line branch. The event is determined to have occurred on a determined segment downstream of the feeder line branch based on the status of the monitored segment and on which segment is the monitored segment. An indication that the event occurred on the determined segment is provided based on determining the monitored segment.

Abstract: A system and method for locating a fault in an electrical distribution system. A transient current waveform description associated with a line fault in an electrical distribution line is received. A time duration of the transient current waveform is determined based on the electrical current verses time waveform. An estimation that the line fault is likely to have occurred on one of the feeder line or the at least one lateral line is made based on a comparison of the time duration of the transient current waveform to a first threshold. An indication, based on the estimation, that the likely line fault likely occurred on one of the feeder line or the at least one lateral line is provided.

Abstract: Systems and methods to combine line fault location probabilities. A first and second location probability distribution are received for a location of an line fault along an electrical line based upon at least electrical current measurements reported by a first electrical current monitor at a first location and at least a second electrical current measurements reported by a second electrical current monitor at a second location. The second electrical current measurements being made within a time interval of the first electrical current measurements. A composite location probability distribution is determined for the location of the line fault along the electrical line based on an algorithm processing the first location probability distribution and the second location probability distribution. The composite location probability distribution is provided.

Abstract: Systems and methods to provide composite fault maps. A first event report is received from a system indicating a first set of location probability distributions of a first event. A second event report is received from a second system that is a different type than the first system indicating a second set of location probability distributions of a second event that is different from the first event. Based upon data in the received reports, the first event is determined to be associated with the second event. A composite fault map is determined that includes composite location likelihood values for the first event and the second event, the composite fault map being determined based on assembling the first set of location probability distributions and the second set of location probability distributions. The the composite fault map is provided to a different process.

Abstract: An outage estimator that generates outage data characterizing a power state for a number of premises serviced by a power grid, the number of premises comprising a first set of the premises and a second set of the premises different from the first set of the premises. The generating includes executing a first stage analysis that estimates the power state for the first set of the premises associated with a set of transformers coupled to a first feeder in the power grid in response to detecting an event message from a smart meter associated with the first set of the premises. The generating also includes executing a second stage analysis that estimates the power state for a second set of premises associated with a set of laterals coupled to a second feeder in the power grid in response to detecting that no event messages have been provided from smart meters associated with the second set of the premises within a predetermined amount of time.

Abstract: Systems and methods to determine events that are associated with one another. Reports of a first, second, and third events are received. Based upon data associated with the first and second event, a determination is made that the first event is associated with the second event. Based upon data associated with the first event and the third event, a determination is made that the first event is not associated with the third event. A presentation is created indicating that the first and second events are related to the second event and that the first and third events are not related. The presentation is presented to a different process.

Abstract: A ticket location system can match each of a plurality of trouble tickets stored in a plurality of electronic records of a first set of electronic records issued for power grid elements of a power grid with a corresponding instance of route data stored in an electronic record of a second set of electronic records. Each instance of route data characterizes a time and date of a route traversed by a service crew during field service of the corresponding trouble ticket. The ticket location system can identify a stop characterized in each instance of the route data. The stop is at least one of a longest stop in the instance of route data and a stop with a duration that exceeds a predetermined amount of time. Additionally, the ticket location system can associate each of the plurality of trouble ticket with a location and a time of the stop in the corresponding route data.
