Bulk Electric System Protection Model Demonstration with 2011 Southwest Blackout in DCAT

Protection equipment modeling is critical to power systems planning and operational studies; it enables more accurate system response when control actions, including protection relays and remedial action schemes (RASs), are adequately modeled and assessed. This paper incorporates a generic protection philosophy in the Dynamic Contingency Analysis Tool (DCAT), and demonstrates its effectiveness by modeling 2011 Pacific Southwest Blackout event autonomously.
