• PhasorXReport: Enables/Disables the phasor channel X (reporting of
PhasorX) by choosing On/Off setting.
• 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
• PhasorXUseFreqSrc: Enables/Disables the contribution of Phasor
channel X in automatic frequency source selection by choosing On/Off
setting. Each voltage-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 (PhasorXUseFreqSrc) to be used as a source of
frequency data for reporting to the PDC client. It is very important to set
this parameter to On for the voltage-connected phasor channels. There is
an automatic frequency source selection logic to ensure an uninterrupted
reporting of the system frequency to the PDC client. More information is
available under the section
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:
• 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 Integer
format is used. It refers to the 4-byte ANUNIT field of the configuration
frames 1, 2 organization and the 8-byte ANSCALE field of the
configuration frame 3 organization defined in IEEE C37.118.2 message
format. The AnalogXRange value can be a number between 3277.0 and
10000000000. This setting is only important if the AnalogDataType
setting is selected as Integer. More information is available under the
section Scaling Factors for ANALOGREPORT
• AnalogXUnitType: Unit type for analog signal X. It refers to the 4-byte
ANUNIT field of the configuration frames 1, 2 organization defined in
IEEE C37.118.2 message format. The options are Single point-on-wave,
RMS of analog input and Peak of analog input.
