Record Phasor Measurement Unit (PMU) Data for Analysis

EPM 9900P PMU/Synchophasor Functionality

The EPM 9900P meter has been enhanced with Phasor Measurement Unit (PMU) functionality meeting the IEEE C37.118.1a-2014 standard. A PMU device measures time-synchronized, phasor (magnitude and phase angle of voltage and current) and related data from a specific location on the electrical grid. The data from multiple PMUs are transmitted to a phasor data concentrator (PDC), which aggregates and time-aligns the data for real time and post analysis.

Collection of Synchrophasor data is useful in applications such as: 

  • Aggregation of instantaneous, time synchronized voltage, current, and frequency at specific locations on the grid for easy greater wide-area system operator situational awareness
  • Determination of stress points of the utility transmission system
  • Detect and aid in restoration an islanded section of the grid after a storm or major outage disturbance
  • Collection and integration of PMU data for visualization in an Energy Management System (EMS). 
EPM 9900P Synchrophasor Features
  • Supports both P and M classes
  • Time sync standard: IRIG-B or IEEE 1588 PTPv2
  • Calculates individual voltage/current phasors, symmetrical components’ phasors, frequency, rate of change of frequency, the meter’s high-speed digital inputs, analog fundamental power, and displacement power factor
  • Data frame rates:
    • 50 Hz - 10/25/50 frames per second
    • 60 Hz - 10/12/15/20/30/60 frames per second
  • Data format: configurable float or integer, polar or rectangular
  • Support for up to two simultaneous clients with Ethernet or Fiber over Ethernet communication

  • Waveform capture can be triggered by status input data inside GOOSE messages. The user can program up to 16 status inputs that will trigger a waveform capture when the information is received via a GOOSE message. The status inputs include digital inputs, limit states, and any other status input supported by the meter.
Unique GOOSE Cross Trigger
  • Fault-based cross trigger of waveform based on GOOSE message
  • Provides system-wide distribution fault analysis on an event
  • Timing better than 200 microseconds is typical
