Identification of power system events using fuzzy logic
MetadataShow full item record
A method for analyzing an electrical power system using fuzzy logic includes: (a) acquiring data representing a signal of interest of the power system; (b) analyzing the signal using at least one fuzzy logic rule, wherein the fuzzy logic rules include: (1) phase level rules which are based on features extracted from a particular phase on the electric power system; (2) segment level rules which are evaluated using information from different phases; and (3) capture level rules which combine truth values obtained from one or more segments; and (c) based on the analysis, detecting and classifying at least one power system event within the power system.
