The reporting ports menus allow specifying the content and rate of reporting on each of
the supported ports. The PMU settings are organized in five logical groups: basic
configuration, calibration, communications, triggering, and recording.
Select the Settings > Metering > Phasor Measurement Unit > Phasor Measurement Unit
> Basic Configuration menu to open the Phasor Measurement Unit configuration window.
Figure 465: 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 PMU.
Function
Range: Enabled, Disabled
Default: Disabled
This setting enables the Phasor Measurement Unit functionality. Any associated
functions (such as the recorder or triggering comparators) do 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 PMU 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 PMU. It corresponds to the IDCODE field of the
data, configuration, header, and command frames of the C37.118 protocol. The PMU
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 PMU 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
PMU. Note that any combination of voltages and currents can be configured as a
source. The current channels can be configured as sums of physically connected
currents. This facilitates PMU applications in breaker-and-a-half, ring-bus, and similar
arrangements. The PMU 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
