Settings for Synchrophasors
Descriptions for some of the settings in Tab le 18.2 are as follows.
MFRMT
Selects the message format for synchrophasor data.
SEL recommends the use of MFRMT := C37.118 for any new PMU applications
because of increased setting flexibility and the expected availability of software
for synchrophasor processors. The PMU still includes the MFRMT := FM setting
choice to maintain compatibility in any systems presently using SEL Fast Mes-
sage synchrophasors.
MRATE
Selects the message rate in messages per second for synchrophasor data.
Choose the MRATE setting that suits the needs of your PMU application. The
PMU supports as many as 60 messages per second if NFREQ = 60 and as many
as 50 messages per second if NFREQ = 50.
