SMAI reference block. Therefore, in order to avoid two different filtering applied to
the 3PHSUM block, both SMAI reference block and 3PHSUM shall be connected to
the same PHASORREPORT instance. In this example (Figure 52), SMAI3 adapts its
filtering according to PHASORREPORT1 instance 2 (due to connection) and
3PHSUM is adapting its filtering according to PHASORREPORT1 instance 1. On the
other hand, since 3PHSUM is set to receive external DFT reference from SMAI3,
therefore If settings for PHASORREPORT1 instances 1 and 2 above differ for
SvcClass or ReportRate, then 3PHSUM block will be affected by two different
filtering at the same time which is not possible. For example in Figure 52, PHASOR2
from PHASORREPORT1 instance 1 may not be fully compliant with IEEE C37.118
standard.
Note: If the SMAI reference block is not connected to any PHASORREPORT block,
then 3PHSUM block can be freely connected to any PHASORREPORT block
regardless of its DFT reference setting.
Note: If more 3PHSUM blocks need to be used, all 3PHSUM blocks (using external
DFT ref) have to be connected to the same instance of PHASORREPORT blocks
(PHASOR1-32 of Instance number 1 or 2).
Note: If settings SvcClass and ReportRate are the same for different instances of
PHASORREPORT blocks, then 3PHSUM block can be freely connected to any of
them regardless of 3PHSUM block DFT reference setting or the reference SMAI
block connection.
Note: Violation of rules 2 or 3 results in non-compliancy with IEEE C37.118 standard
for some of the synchrophasors. In case of rule 2 violation, the non-compliancy only
applies to synchrophasors from instance 2 and the synchrophasors from instance 1
will be still compliant. The non-compliancy with the standard may be quite obvious
as in case of rule 2 violation with different SvcClass settings. This produces big angle
error. On the other hand, it may be difficult to detect the non-compliancy with the
standard if rule 2 is violated with different ReportRates, or if rule 3 is violated. In such
cases, the synchrophasors may only fail to comply (with small error) in some
particular test case(s).

Application Manual under section Basic IED functions.

Setting guidelines

Based on the functionality and appearance in PCM600, the PMU reporting
functionality is categorized into 4 different categories (function block) as follows:
1. PMUREPORT
2. PHASORREPORT
3. ANALOGREPORT
4. BINARYREPORT
