摘要： In one embodiment, a requesting device (e.g., head-end application) requests a phase-related response from an end-point that does not know its phase in a polyphase power source system. In response, the requesting device receives the phase-related response from the end-point, where the response relays an identification of the end-point and related phase information without indicating an actual phase of the end-point, e.g., on which power-line is a response generated or at which time is a zero-crossing of the power source's waveform. The phase information of the phase-related response may then be correlated to a known phase of a known-phase device, such that the actual phase of the end-point may be identified based on the correlation.

摘要： 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.
