CHAPTER 5: SETTINGS
This section contains basic Phasor Measurement Unit (PMU) data, such as functions, source settings, and names.
— This setting enables the LOGICAL Device PMU 1 functionality. Use this setting to permanently enable or
PMU 1 FUNCTION
disable the feature.
— This setting assigns a numerical ID to the PMU. It corresponds to the IDCODE field of the data,
PMU 1 IDCODE
configuration, header, and command frames of the IEEE C37.118 protocol. The PMU uses this value when sending data,
configuration, and header frames; and it responds to this value when receiving the command frame. This is used when
only data from one PMU is present.
— This setting assigns an alphanumeric ID to the PMU station. It corresponds to the STN field of the
PMU 1 STN
configuration frame of the IEEE C37.118 protocol. This value is a 16-character ASCII string as per the IEEE C37.118
standard.
— This setting specifies one of the available L30 signal sources for processing in the PMU. Any
PMU 1 SIGNAL SOURCE
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 symmetrical components (0, 1, and 2) of both voltages and currents. When configuring
communication and recording features of the PMU, the user can select, from the above superset, the content to be sent
out or recorded. When one source is selected by one PMU, it cannot be selected by another PMU.
PMU 1 CLASS (Range P, M, None)
selected for class P synchrophasors and if the system frequency is 50 or 60 Hz, respectively.
PMU 1 NETWORK REPORTING FORMAT
IEEE floating point numbers. This setting complies with bit-1 of the FORMAT field of the C37.118 configuration frame. Note
that this setting applies to synchrophasors only; the user-selectable FlexAnalog channels are always transmitted as 16-bit
integer values.
