V&R Energy, a Los Angeles-based technology and consulting company, is supplying its Region of Stability Existence (ROSE) application to the Western Electricity Coordinating Council's (WECC) Western Interconnection Synchrophasor Program (WISP).

ROSE, a voltage stability analysis software, uses phasor measurement unit (PMU) data to track the power system's current operating state, analyze power system conditions and alert operators of changes that could lead to voltage instability.

WISP participants are installing more than 300 new or upgraded PMUs to identify and analyze system vulnerabilities in real time, as well as to detect evolving disturbances on the Western Bulk Electric System. Scheduled for completion on March 31, 2013, this “early warning” mechanism will enable WECC and WISP’s partner entities to take timely actions to help avoid widespread system blackouts, according to V&R.
