Phasor Measurement Unit (PMU)

Synchrophasor Measurements Improve Power System Stability

  • Provide system operators with wide-area situational awareness through improved visibility into dynamic grid conditions.
  • Determine stress points of the electric power system.
  • Detect and aid in restoring an islanded section of the grid after a storm or major outage disturbance.
  • Instantaneous measurements provide early warning detection alerts that SCADA systems miss.
  • Provides built-in system wide PMU analysis for future implementation of big data analytics, artificial intelligence, and machine learning to proactively improve power systems and prevent outages.
