  • FAULT LOCATION ESTIMATION USING INCREMENTAL QUANTITIES
    Publication number: 20240118330
    Abstract: A method and a system are used to analyze incremental quantities. The electrical measurements associated with a loop in a multiple-phase electric power delivery system are obtained before a fault occurred on the loop and after the fault occurred on the loop, and differences between the electrical measurements are used to determine incremental quantities. The incremental quantities are used to determine a location of the fault on the loop. Multiple loops in the multiple-phase electric power delivery system may be monitored to determine corresponding fault locations on each loop.

  • Systems and methods for enabling a maintenance mode of protection devices in digital secondary systems
    Patent number: 11550285
    Abstract: Systems, methods, and devices are provided for determining a maintenance mode of one or more merging units of an electric power delivery system using an intelligent electronic device that may rely on communication from wired (or wireless) electrical measurement devices. The intelligent electronic device may be a line relay. The merging units may provide data to the line relay including at least one bit indicating a maintenance mode of each merging unit. If a maintenance mode bit from a particular merging unit indicates that the merging unit is in the maintenance mode, logic of the line relay may determine if a maintenance mode override is received. If so, the line relay may disregard the maintenance mode bit and process the data from the merging unit. If the logic determines that the merging unit is in the maintenance mode, the line relay may force data from the merging unit to zero.
