Wide area measurement system

There are settings for Phasor type (positive sequence, negative sequence or zero
sequence in case of 3-phase phasor and L1, L2 or L3 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
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
Blocks Connection Rules.
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.

Figure 34 shows both instances of the PHASORREPORT function blocks. The
instance number is visible in the bottom of each function block. For each instance,
there are four separate PHASORREPORT blocks including 32 configurable phasor
channels (8 phasor channels in each PHASORREPORT block). Each phasor
channel can be configured as a 3-phase (symmetrical components positive/
negative/zero) or single-phase phasor (L1/L2/L3).
