One Algorithm, Multiple Applications

Developed collaboratively with Eaton’s Microgrid & DER Control Platform group, the MPCV-NXG relay has the capability of identifying the type of backfeed. An accompanied external enclosure injects reactive power.

DER (Distributed Energy Resources)

Anomalies (abnormal conditions) are flagged while generation is identified as a normal system conditions. Generation flows back without desensitizing the network relay functionality or the use of additional expensive monitoring relays on the system.

FDR (Feeders from Different Substations)

The algorithm manages corrections using the same analysis from the DER model.
