2. PHASORREPORT is the function block responsible for reporting the synchrophasors. Each
instance of PMUREPORT function block has 32 phasor channels with the following setting
parameters; where X is a number from 1 to 32:

3. ANALOGREPORT is the function block responsible for reporting the analog values. Each
instance of ANALOGREPORT function block has 24 analog channels with the following
setting parameters; where X is a number from 1 to 24:

• 30/25 fr/s (60/50Hz)
• 60/50 fr/s (60/50Hz)
• 120/100 fr/s (60/50Hz)
• 240/200 fr/s (60/50Hz)
The first number is identifying the reporting rate in a 60Hz system, and the second
number is the reporting rate in a 50Hz system. For example, if the selected setting is
15/10 fr/s (60/50Hz) , this means that the synchrophasor data reporting rate would
be 15 frames per second if the system frequency is 60Hz. Likewise, if the system
frequency is 50Hz, the selected rate is equal to 10 frames per second.
RptTimetag : It refers to the method of time-tagging used in the IED which is related
to the phasor estimation and filtering technique. The options are
MiddleSample and LastSample . The time-stamp of the PMU output represents the
phasor equivalent, frequency, and ROCOF of the power system signal at the time it
is applied to the PMU input. All of these estimates must be compensated for PMU
processing delays including analog input filtering, sampling, and estimation group
delay. If the sample time tags are compensated for all input delays, the time tag of
the sample in the middle of the estimation window can be used for the phasor
estimation (output) time tag as long as the filtering coefficients are symmetrical
across the filtering window.
Note: It is recommended to set this parameter on

choosing
PhasorX : The group selector for PhasorX. Here, the user can select the type of
reported synchrophasor from the phasor channel X as either a 3-phase symmetrical
component or a single-phase phasor. The options are as follows:
• A
• B
• C
• NEGSEQ
• POSSEQ
• ZEROSEQ

automatic frequency source selection by choosing
connected preprocessor block delivers the frequency data, derived from the analog
input AC voltage values, to the respective voltage phasor channel. Every phasor
channel has a user-settable parameter (
of frequency data for reporting to the PDC client. It is very important to set this
On for the voltage-connected phasor channels. There is an automatic
parameter to
frequency source selection logic to ensure an uninterrupted reporting of the system
frequency to the PDC client. More information is available under the section
Frequency reporting.
AnalogXRange : This parameter defines a range between -AnalogXRange and
+AnalogXRange for AnalogX value. The range will be used by the IED to apply a
proper scale factor to the AnalogX values when
