  • Patent number: 10655984
    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.

  • Patent number: 10489019
    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.

  • Patent number: 10439434
    Abstract: Embodiments of the present invention provide for impedance shift analysis for failure prediction in an electrical power distribution network. In an embodiment of the invention, the method includes receiving a sequence of electrical measurements indicative of an impedance measured for a segment of an electrical power distribution network over a period of time. Then, a set of impedance measurements is computed for the period of time and the set of impedance measurements is organized into a distribution correlating each one of the impedance measurement with a corresponding computed current measurement. A trend line for the distribution is identified and a slope computed of the trend line. Finally, on condition that the slope exceeds a threshold steepness, an impending failure in the segment is determined and a notification transmitted over a computer communications network to an end user requesting physical inspection of the segment.

  • Patent number: 10391448
    Abstract: A method, controller and computer readable storage medium for dosing ammonia in a selective catalytic reduction (SCR) system for reducing NOx emissions in a flue gas, are disclosed. The method generally includes calculating a running long term average of NOx emissions, calculating a running short term average of NOx emissions and automatically adjusting an instantaneous NOx setpoint based on the running long term and short term averages to ensure compliance with a permit limit. The ammonia dosing requirement is based on a chemical mass-balance approach, and accuracy is enhanced by adjusting for the NO2 to NO composition of NOx.

  • Patent number: 10223906
    Abstract: Systems and methods to determine open neutral conditions in a poly-phase electrical connection. Voltage measurements of at least two phases of poly-phase electrical power delivered to a customer premises are received from an electrical meter via a communications network providing communications among many electrical meters. The electrical power is delivered with a neutral conductor separate from the at least two phases. A first voltage measurement of a first phase and a second voltage measurement of a second phase of at least two phases are received. Based on determining that a difference between the first voltage measurement and the second voltage measurement exceeds a phase-to-phase threshold amount, a likely open neutral condition in the neutral conductor is determined. An indication of the likely open neutral condition is sent to a customer service system.
