Our mission

The NASPI Control Room Solution Task Team’s mission is to work collectively with other NASPI task teams to advance the use of real-time synchrophasor applications for the purpose of improving control room operations and grid resilience and reliability. The CRSTT will use 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 synchrophasor applications.

CRSTT: Using Synchrophasor Data during System Islanding Events and Blackstart Restoration

This paper explores the value that can be added in the near future by using synchrophasor data and applications in the areas of system islanding detection and blackstart restoration. It includes descriptions of:

  • Related functional entity roles and responsibilities
  • Ways that synchrophasor technology may be used to detect islanding events and aid entities in meeting certain restoration objectives
  • Related commercial applications that are currently on the market for which the NASPI CRSTT received information from application users or vendors

This paper may be updated in the future to include additional applications, functionality and methodologies as new information is provided.

CRSTT: Using Synchrophasor Data for Phase Angle Monitoring

This paper addresses how synchrophasor technology can be used for phase angle monitoring and describes the various synchrophasor-based applications being used by electric utilities and grid operators presently. Uses for phase angle monitoring include:


• Wide-area situational awareness and visualization
• Line reclosing
• Verifying operation of synch check relays
• Setting alarms and alerts
• Improving state estimator solutions.


This paper may be updated in the future to include additional applications, update features of existing applications, functionality and methodologies as new information is received.
