Systems and methods for automatically characterizing disturbances in an electrical system

A system for automatically categorizing disturbances in an electrical system, comprising:

• a processor;
• a memory device;
• and
• one or more processors, in communication with the memory device, configured to:
• process electrical measurement data from, or derived from, at least one energy-related waveform captured by at least one intelligent electronic device (IED) in the electrical system to identify disturbances in the electrical system;
• in response to identifying the disturbances in the electrical system, analyze and categorize samples of the at least one energy-related waveform associated with the identified disturbances into one of a plurality of disturbance categories, the disturbance categories including:
• (a) voltage sags due to upline electrical disturbances, (b) voltage sags due to downline electrical system faults, (c) voltage sags due to downline transformer and/or motor magnetization, and (d) voltage sags due to other downline disturbances;
• and
• determine a disturbance categorization for the at least one energy-related waveform associated with the identified disturbances based on the categorization of the samples of the at least one energy-related waveform, the disturbance categorization being selected from one of the disturbance categories.

A non-transitory computer medium storing computer executable code, which when executed by one or more processors, is configured to implement a method of automatically categorizing disturbances in an electrical system, the method comprising:

• processing electrical measurement data from, or derived from, at least one energy-related waveform captured by at least one intelligent electronic device (IED) in the electrical system to identify disturbances in the electrical system to identify disturbances in the electrical system;
• in response to identifying the disturbances in the electrical system, analyzing and categorizing samples of the at least one energy-related waveform associated with the identified disturbances into one of a plurality of disturbance categories, the disturbance categories including:
• (a) voltage sags due to upline electrical disturbances, (b) voltage sags due to downline electrical system faults, (c) voltage sags due to downline transformer and/or motor magnetization, and (d) voltage sags due to other downline disturbances;
• and
• determining a disturbance categorization for the at least one energy-related waveform associated with the identified disturbances based on the categorization of the samples of the at least one energy-related waveform, the disturbance categorization being selected from one of the disturbance categories.
