Phasors Included in the Data q
Terminal Name, Relay Word Bit, Alternate Terminal Name
Specify the terminal for Synchrophasor measurement and transmission in the
synchrophasor data stream q.
This is a freeform setting category for enabling the terminals for synchrophasor
measurement and transmission. This freeform setting has three arguments. Spec-
ify the terminal name (any one of W, X, S, Y, or Z) for the first argument. Specify
any Relay Word bit for the second argument. Specify the alternate terminal name
(any one of W, X, S, Y, or Z) for the third argument.
The second and third arguments are optional unless switching between terminals
is required. Whenever the Relay Word bit in the second argument is asserted the
terminal synchrophasor data are replaced by the alternate terminal data.
