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.
- The PMU provides the following synchronized measurements:
- Individual voltage/current phasors (Va, Vb, Vc, Ia, Ib, Ic).
- Symmetrical components phasors (V0, V1, V2, I0, I1, I2).
- Frequency and Rate of Change of Frequency (ROCOF).
- Built-in digital inputs.
- Analog
- Fundamental power: (watt total and per phase, VA total and per phase, VAR total and per phase).
- Displacement power factor: (total and per phase)
- Supports P (Fast Response) or M (Precise Measurement) classes, user selectable.
- Data frame rates for 50 Hz: 10/25/50 frames per second; for 60 Hz: 10/12/15/20/30/60 frames per second.
- Data format: Configurable float or integer, polar or rectangular.
- Time sync standard: IRIG-B or IEEE 1588 PTPv2.
- Number of sessions: up to 2 simultaneous clients.
- Supports Ethernet or Fiber over Ethernet: TCP communication for header, configuration, and command; UDP communication for data, including unicast, broadcast, and multicast.
