Rapidly Deployable Recovery Transformers - A High-Voltage Transformer to Respond to Grid Outages

摘要

ANYONE LIVING IN NORTH AMERICA WAS CERTAINLY AWARE OF, IF NOT affected by, the 14 August 2003 blackout. The investigation into the blackout shows that the cause was an unfortunate chain of events that disrupted power flow to key areas of load and resulted in confusion over, the status of the power delivery network. Electric demand continued, and without an effective way to move power into major metropolitan areas, the system became unstable. However, anyone who understands the utility grid knows that the interconnection points and the effective exchange of power are key to maintaining system stability. At the heart of the interconnections, where power flows from transmission lines to the distribution network, are large power transformers that step the transmission voltage down toward that needed for final use.
