Figure 399: Phasor measurement unit configuration settings
The settings allow for the configuration of basic synchrophasor data, such as functions,
source settings, and names. The following settings are available for each phasor
measurement unit.
Function
Range: Enabled, Disabled
Default: Disabled
This setting enables the phasor measurement unit functionality. Any associated
functions (such as the recorder or triggering comparators) will not function if this setting
is "Disabled". Use the command frame to force the communication portion of the feature
to start/stop transmission of data. When the transmission is turned off, the phasor
measurement unit is fully operational in terms of calculating and recording the phasors.
IDcode
Range: 1 to 65534 in steps of 1
Default: 1
This setting assigns a numerical ID to the phasor measurement unit. It corresponds to
the IDCODE field of the data, configuration, header, and command frames of the
C37.118 protocol. The phasor measurement unit uses this value when sending data,
configuration, and header frames and responds to this value when receiving the
command frame.
STN
Range: 16 alphanumeric characters
Default: GE-UR+PMU
This setting assigns an alphanumeric ID to the phasor measurement unit station. It
corresponds to the STN field of the configuration frame of the C37.118 protocol. This
value is a 16-character ASCII string as per the C37.118 standard.
Source
Range: LINE (SRC 1), BKR 1 (SRC 2), BKR 2 (SRC 3)
Default: LINE (SRC 1)
This setting specifies one of the available D90
phasor measurement unit. Note that any combination of voltages and currents can be
configured as a source. The current channels could be configured as sums of physically
connected currents. This facilitates phasor measurement unit applications in breaker-
and-a-half, ring-bus, and similar arrangements. The phase measurement unit feature
calculates voltage phasors for actual voltage (A, B, C, and auxiliary) and current (A, B, C,
and ground) channels of the source, as well as symmetrical components (0, 1, and 2) of
