Automated Fault and Disturbance Analysis

September 11, 2023 @ 5:30 pm - 6:30 pm

  • Abstract: Power system experience faults and disturbances that may negatively affect its desired performance. Over the years many sources of data have been used to automate fault and disturbance detection, classification, and characterization with a goal of helping operators, planners and protection engineers in assuring timely manual or automated reaction to faults and disturbances, particularly if they are poised to endanger safe, reliable, and secure electric grid operation. The talk focuses on three key considerations when designing such automated systems: a) selection of sources of data, b) choices of algorithms for reaching the conclusions, and c) mitigation measure for preventing or reducing impacts of fault and disturbances. The data discussion differentiates between the time synchronized and unsynchronized field waveform recordings, and the use of data from relays, fault recorders and PMUs. The choices of algorithms depend on the purpose of the analysis, so the differentiation is made between post-mortem, online and predictive analysis. The mitigation measures depend on the goal of assisting operators and planers or designing IEDs for automated control to mitigate the fault and disturbance impacts. The talk ends with examples from T&D and DER applications.
