Application

The phasor measurement reporting block moves the phasor calculations into an IEEE
C37.118 and/or IEEE 1344 synchrophasor frame format. The PMUREPORT block
contains parameters for PMU performance class and reporting rate, the IDCODE and
Global PMU ID, format of the data streamed through the protocol, the type of reported
synchrophasors, as well as settings for reporting analog and digital signals.
The message generated by the PMUREPORT function block is set in accordance with
the IEEE C37.118 and/or IEEE 1344 standards.
There are settings for Phasor type (positive sequence, negative sequence or zero
sequence in case of 3-phase phasor and A, B or C in case of single phase phasor),
PMU's Service class (Protection or Measurement), Phasor representation (polar or
rectangular) and the data types for phasor data, analog data and frequency data.
Synchrophasor data can be reported to up to 8 clients over TCP and/or 6 UDP group
clients for multicast or unicast transmission of phasor data from the IED. More
information regarding synchrophasor communication structure and TCP/UDP
configuration is available in section
Protocol Configuration.
Multiple PMU functionality can be configured in the IED, which can stream out same
or different data at different reporting rates or different performance (service) classes.
There are 2 instances of PMU functionality available in the IED. Each instance of
PMU functionality includes a set of PMU reporting function blocks tagged by the same
instance number (1 or 2). As shown in the following figures, each set of PMU
reporting function blocks includes PMUREPORT, PHASORREPORT1-4,
ANALOGREPORT1-3, and BINARYREPORT1-3 function blocks. In general, each
instance of PMU functionality has 32 configurable phasor channels
(PHASORREPORT1–4 blocks), 24 analog channels (ANALOGREPORT1-3 blocks),
and 28 digital channels (24 digital-report channels in BINARYREPORT1-3 and 4
trigger-report channels in PMUREPORT function block). Special rules shall be taken
into account in PCM600 for Application Configuration and Parameter Settings of
multiple PMUREPORT blocks. These rules are explained in the the Application
Manual in section PMU Report Function Blocks Connection
Figure 33 shows both instances of the PMUREPORT function block. As seen, each
PMUREPORT instance has 4 predefined binary input signals corresponding to the Bits
03-00: Trigger Reason defined in STAT field of the Data frame in IEEE C37.118.2
standard. These are predefined inputs for Frequency Trigger, Rate of Change of
Frequency trigger, Magnitude High and Magnitude Low triggers.
