US 8,805,598 B2 · Dynamic configuration of distribution feeder parameters in a power grid

Abstract

In one embodiment, a system identifies a grid topology of a plurality of distribution automation (DA) devices of a distribution feeder circuit in a power grid, and determines parameters for each of the DA devices of the distribution feeder circuit based on the grid topology e.g., protection parameters such that DA devices further from a power source in the power grid up to a normally open point (NOP) are configured to trigger protection earlier than DA devices closer to the power source. The DA devices may then be configured with respective parameters as determined, and in response to detecting a change of the grid topology, updated parameters may be determined for one or more of the DA devices based on the changed grid topology. The system then reconfigures respective parameters of each of the DA devices that have updated parameters due to the change of the grid topology.
