Figure 467: Phasor Measurement Unit communications configuration
The following settings are available for the communication port on each PMU.
Type
Range: None, Network
Default: None
This setting specifies the first communication port for transmission of the PMU data. The
three ports are configured under individual menus.
PHS-1, PHS-2, PHS-3,..., PHS-14
Range: Off, Va, Vb, Vc, Vx, Ia, Ib, Ic, Ig, V1, V2, V0, I1, I2, I0
Default: Off
These settings select synchrophasors to be transmitted from the superset of all
synchronized measurements. The available synchrophasor values are
–
Va — The first voltage channel, either Va or Vab
–
Vb — The second voltage channel, either Vb or Vbc
–
Vc — The third voltage channel, either Vc or Vca
–
Vx — The fourth voltage channel
–
Ia — Phase A current, physical channel, or summation as per the source settings
–
Ib — Phase B current, physical channel, or summation as per the source settings
–
Ic — Phase C current, physical channel, or summation as per the source settings
