Abstract: A system and method for nuisance-trip decision management in an electric power system using data analytics comprising, a protection system, PS, and at least one electrical protection circuit, EPC. The PS comprising, a plurality of sensors configured to measure data; a memory configured to store an updated data of nuisance-trip events and a plurality of nuisance-trip parameters detected or generated on the electric power system over a period; a processor configured to perform hybrid machine learning (HML) based on the measured data from the plurality of sensors for a nuisance-trip condition and communicate with a neighboring PS; a protection microcontroller configured to allow or avoid tripping at least one electronic tripping circuit provided in the at least one EPC by communicating with the processor and the neighboring PS.

Abstract: A system and method for protecting an electric power distribution system integrated with a hybrid machine-learning model includes a plurality of field protection systems, a plurality of electrical switching circuits, and a local area network. Data from each of the plurality of field protection systems that is connected to the electrical switching circuits that are configured for protecting the electric power distribution system, is transmitted to the cloud. The received data is processed to identify a change in patterns and compute an error related to the HMLM in comparison with the processed data. The HMLM that is implemented in the plurality of FPS is calibrated to minimize the error and send updates to develop a new decision making firmware thereby to control actuation of the plurality of the electrical switching circuits.
