On the afternoon of August 14, 2003 a sequence of improbable events caused all the transmission lines feeding the city of Cleveland from the southeast to trip.  This led to a massive power flow reversal as other transmission lines around the city were forced to handle the excess load.  Unable to do so, the result was the largest single power outage ever in the United States.  In the years that followed it was learned that throughout that day, a massive phase imbalance had grown between Cleveland and West Michigan.  Had this phase imbalance been detected the blackout would have been averted.  This led to the development and deployment of synchrophasor measurement devices – devices capable of measuring relative phase angles – on transmission networks across North America.

For several years now, Aclara Research and Development has been experimenting with synchrophasor technologies that could bring this technology, previously only available on transmission networks, to distribution networks.  In this talk, we will provide an overview of what synchrophasor measurement devices are, how they work, and what they can detect that more traditional power line sensors cannot detect.  We will show the results of recent field tests on real distribution networks of synchrophasor measurement devices in the early stages of product development.  Utilities that are interested in cutting edge solutions to problems such as phase identification, power flow monitoring, impedance estimation, and distributed generation control are encouraged to attend.
