ES-PDC

Phasor data concentrators are installed at power plants to collect data from phasor measurement units, and stream it to data processing centers. Synchrophasor data allows power system operator to identify power system conditions and to monitor its dynamics. Real-time data provide instantaneous overview of the power system, allowing the operator to detect the abnormal conditions and to determine their source.

ES-PDC runs on industrial fanless PC. ES-PDC supports data exchange via IEEE C37.118.2, calculates the values of additional electical quantities on the fly, records cyclic and emergency archives of a configurable depth.
