6.2.2 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
C37.118 Phasor Measurement Data Streaming 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 Rules.
Figure 34 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.
