Figure 10:
Process bus application of voltage sharing and synchrocheck
REC615 and RER615 support IEC 61850 process bus with sampled values of analog
currents and voltages. The measured values are transferred as sampled values using
the IEC 61850-9-2 LE protocol which uses the same physical Ethernet network as the
IEC 61850-8-1 station bus. The intended application for sampled values is sharing the
measured voltages from REC615 or RER615 protection relay to other devices with
phase voltage based functions and 9-2 support.
REC615 and RER615 protection relays with process bus based applications use IEEE
1588 v2 Precision Time Protocol (PTP) according to IEEE C37.238-2011 Power
Profile for high accuracy time synchronization. With IEEE 1588 v2, the cabling
infrastructure requirement is reduced by allowing time synchronization information
to be transported over the same Ethernet network as the data communications.
