Automated Fault and Disturbance Analysis:

Whenever a fault or disturbance in a power system occurs several IEDs are triggered and several data recordings are generated. Automated processing and analysis of substation disturbance data is an effective way to filter important information from the collected data and convert the extracted information into knowledge. Configuring automated analysis systems to allow for efficient data integration and analysis of substation data in timely fashion has been recognized as a challenge. Implementing automated fault and disturbance analysis requires continuous and proper handling of the configuration settings. To process substation IED data we need to know relevant IED settings, channel assignments, and parameters of the power system components being monitored. The paper discusses configuration challenges pertinent to automated fault analysis solutions as they were implemented in three utilities over the years.
