GE Multilin F60 Feeder Protection System 5-1215 SETTINGS 5.4 SYSTEM SETUP5• PMU1 PHS-1 to PMU1 PHS-14: These settings specify synchrophasors to be transmitted from the superset of all syn-chronized measurements. The available synchrophasor values are tabulated below.These settings allow for optimizing the frame size and maximizing transmission channel usage, depending on a givenapplication. Select “Off” to suppress transmission of a given value.• PMU1 PHS-1 NM to PMU1 PHS-14 NM: These settings allow for custom naming of the synchrophasor channels. Six-teen-character ASCII strings are allowed as in the CHNAM field of the configuration frame. These names are typicallybased on station, bus, or breaker names.• PMU1 A-CH-1 to PMU1 A-CH-16: These settings specify any analog data measured by the relay to be included as auser-selectable analog channel of the data frame. Up to 16 analog channels can be configured to send any FlexAnalogvalue from the relay. Examples include frequency, rate of frequency change, active and reactive power, per phase orthree-phase power, power factor, temperature via RTD inputs, and THD. The configured analog values are sampledconcurrently with the synchrophasor instant and sent as 32-bit floating-point values scaled to Engineering units.• PMU1 A-CH-1 NM to PMU1 A-CH-16 NM: These settings allow for custom naming of the analog channels. Sixteen-character ASCII strings are allowed as in the CHNAM field of the configuration frame.• PMU1 D-CH-1 to PMU1 D-CH-16: These settings specify any digital flag measured by the relay to be included as auser-selectable digital channel of the data frame. Up to sixteen digital channels can be configured to send any Flex-Logic operand from the relay. The configured digital flags are sampled concurrently with the synchrophasor instant.These values are mapped into a two-byte integer number, with byte 1 LSB corresponding to the digital channel 1andbyte 2 MSB corresponding to digital channel 16.• PMU1 D-CH-1 NM to PMU1 D-CH-16 NM: These settings allow for custom naming of the digital channels. Sixteen-character ASCII strings are allowed as in the CHNAM field of the configuration frame.• PMU1 D-CH-1 NORMAL STATE to PMU1 D-CH-16 NORMAL STATE: These settings allow for specifying a normalstate for each digital channel. These states are transmitted in configuration frames to the data concentrator.C37.118 PMU 1 CONFIGURATIONPATH: SETTINGS SYSTEM SETUP PHASOR MEASUREMENT BASIC CONFIGURATION PMU 1 PMU 1 BASIC CONFIGU-RATION 37.118 PMU 1 CONFIGURATIONPMU 1 FORMAT: This setting selects whether synchrophasors are reported as 16-bit integers or 32-bit IEEE floating pointnumbers. This setting complies with bit-1 of the FORMAT field of the IEEE C37.118 configuration frame. This settingapplies to synchrophasors only; the user-selectable FlexAnalog channels are always transmitted as 16-bit integer values.SELECTION MEANINGVa First voltage channel, either Va or VabVb Second voltage channel, either Vb or VbcVc Third voltage channel, either Vc or VcaVx Fourth voltage channelIa Phase A current, physical channel or summation as per the source settingsIb Phase B current, physical channel or summation as per the source settingsIc Phase C current, physical channel or summation as per the source settingsIg Fourth current channel, physical or summation as per the source settingsV1 Positive-sequence voltage, referenced to VaV2 Negative-sequence voltage, referenced to VaV0 Zero-sequence voltageI1 Positive-sequence current, referenced to IaI2 Negative-sequence current, referenced to IaI0 Zero-sequence current 37.118 PMU 1 CONFIGURATIONPMU 1 FORMAT:IntegerRange: Integer, Floating-pointMESSAGE PMU 1 STYLE:PolarRange: Polar, Rectangular
