Mission

The Control Room Solutions Task Team's (CRSTT's) mission is to work collectively with other NASPI task teams to advance the use of real-time synchronized measurements for the purpose of improving control room operations and grid reliability. This team will utilize its experience and regional diversity to provide advice, direction, support and guidance to NASPI stakeholders and other organizations involved in the development and implementation of real-time synchronized measurement applications.

EA002 - Using Synchrophasor Data to Analyze Concurrent Fault Events

Release Date
Document Subject Area
Event Analysis
CRSTT Use Case
Description
A 69Kv line trip occurred during a storm where the fault was cleared properly by the line protective equipment. Within seconds an area generator trip was observed. When comparing the synchrophasor data it was clear that the unit trip occurred within cycles of the transmission fault indicating the...
