Reliability Indices and Performance Statistics for Transmission Elements of the North American Bulk Power System

摘要

The paper presents results of the study of the North American inventory and outage data for the transmission elements (ac circuits and transformers) of the bulk power system collected in NERC's Transmission Availability Data System (TADS). Basic reliability indices and performance statistics (e.g., annual outage frequency, outage duration, mean time to forced outage) are derived and statistically compared among voltage classes. The comparison of the transmission element reliabilities and availabilities for the TADS elements is also provided. This is the first study to comprehensively include the years of collection for planned outages.
