ES-PDC (Phasor Data Concentrator) receives and time-synchronizes phasor data from multiple phasor measurement units (PMUs) to produce a real-time, time-aligned output data stream.

A PDC can exchange phasor data with PDCs at other locations. Through use of multiple PDCs, multiple layers of concentration can be implemented within an individual synchrophasor data system.

  • Collect and time-synchronize phasor data from PMU;
  • save all PMU data
