US 12,591,011 B1 · Heuristic-based adaptive system for use with one or more numerical relays

Abstract

An adaptive system is implemented for use with one or more numerical relays. A plurality of features associated with relay operational profile data is input into a plurality of candidate models, and each candidate model is evaluated for one or more performance metrics. A predictive model is selected for fault detection based on the sensitivity and specificity of the predictive model, and a metaheuristic process is used to evaluate various combinations of relay settings for the numerical relays in an electrical network and determine a first set of relay settings based on the evaluation. The electrical network is monitored to detect one or more relay state transitions indicative of one or more changes in relay performance or network conditions, and if one or more relay state transitions are detected, the first set of relay settings are adjusted to enhance performance of the electrical network.
