Section 6
Wide area measurement system
PMU clients are receiving the same UDP stream from the same UDP group (UDP client
group[x]).
As shown in Figure 33, there are maximum 2 instances of PMUREPORT function blocks
available in the IED. Each UDP client group[x] can only connect to one of the PMUREPORT
instances at the same time. This is defined in the PMU by the parameter
which is used to define the instance number of PMUREPORT function block that must send
data on this UDP stream (UDP client group[x]).
The data streams in the IED can be sent as unicast or as multicast. The user-defined IP address
set in the parameter
Multicast. The address range 224.0.0.0 to 239.255.255.255 (Class D IP addresses) is treated as
multicast. Any other IP address outside this range is treated as unicast and the UDP data will
be only sent to that specific unicast IP address. In addition to
UDPDestPort[x] parameter is used to define the UDP destination port number for UDP client
group[x].
In case of multicast IP, it will be the network switches and routers that take care of replicating
the packet to reach multiple receivers. Multicast mechanism uses network infrastructure
efficiently by requiring the IED to send a packet only once, even if it needs to be delivered to a
large number of receivers.
If there are more than one UDP client group defined as multicast, the user shall set different
multicast IP addresses for each UDP group.
The PMU clients receiving the UDP frames can also connect to the IED to request (command
frame) config frame 1, config frame 2, config frame 3, or header frame, and to disable/enable
real time data. This can be done by connecting to the TCP port selected in
TCPportUDPdataCtrl[x] for each UDP group. This connection is done using TCP. The IED allows
4 concurrent client connections for every
group[x]).

6.2.2 Application
The phasor measurement reporting block moves the phasor calculations into an IEC/IEEE
60255-118 (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
