System and method for improving identification of issues associated with detecting abnormal conditions

Abstract

Systems and methods for improving the identification of issues associated with detecting an abnormal condition (e.g., an electrical transient voltage) in an electrical system are disclosed herein. For example, due to metering constraints of an intelligent electronic device (IED) responsible for identifying an abnormal condition in an electrical system, the abnormal condition may be difficult to distinguish. In one aspect of the present disclosure, a method of automatically identifying metrology constraints for one or more IEDs in an electrical system includes capturing at least one energy-related waveform using at least one of the IEDs in the electrical system, and processing the electrical measurement data from or derived from the at least one energy dependent waveform to identify an abnormal characteristic in the electrical system. For example, the abnormal characteristic may indicate an abnormal condition in the electrical system. In response to identifying anomalous characteristics in the electrical measurement data, an event constraint model is established based on or by using the identified anomalous characteristics. Once established, the event constraint model is analyzed to determine whether the at least one energy related waveform is sufficiently captured by at least one of the IEDs. In response to determining that the at least one energy-related waveform is not sufficiently captured, one or more actions may be taken to address insufficient capture.

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of, and priority to, U.S. Provisional Application No. 63 / 127257, filed December 18, 2020, and U.S. Provisional Application No. 63 / 162,321, filed March 17, 2021, filed under 35U. S.C. §119(e), and is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to electrical / power systems, and more particularly, to systems and methods for improving identification of problems associated with detecting abnormal conditions (eg, electrical transient voltages) in electrical systems. Background technique [0004] It is well known that electrical transient voltages may originate inside an energy consumer's facility or outside the utility's grid, and can propagate through electrical and data systems at different levels. The source of damaging transient voltages can be obvious - such as a lightning strike during a thunderstorm - or subtle -...

Problems solved by technology

[0006] Because damage due to transient voltages may not be apparent, identifying the root cause of equipment damage is challenging and is often diagnosed as "unknown"

Many integrated circuits and components fail due to voltage transients, and large equipment such as induction motors are also susceptible to costly voltage transient damage
