Synchrophasors
Settings for Synchrophasors
Ethernet Port Settings
The settings found in Table 18.4 are used for configuring synchrophasor data
transmission over an Ethernet port.
Descriptions for some of the settings in Tab le 18.4 are as follows.
EPMIP
Setting this to Y enables synchrophasor data transmission over Ethernet port. Set-
ting this to N disables the synchrophasor data transmission over Ethernet port.
The EPMIP := Y settings choice can be made when Global setting EPMU := N.
This setting combination will result in the relay ignoring any incoming synchro-
phasor requests regardless of whether the Ethernet port settings are correct or not.
PMOTS[2]
Selects the PMU Output transport scheme for session 1 and 2, respectively.
➤ PMOTS[2] := TCP establishes a single, persistent TCP socket for
transmitting and receiving synchrophasor messages (both commands
and data), as illustrated in Figure 18.3.
