(50 Hz), the L30 will generate a reporting mismatch message if the selected rate is not set as 10 Hz, 12 Hz, 15 Hz,
20 Hz, 30 Hz, 60 Hz, or 120 Hz (or 10 Hz, 25 Hz, 50 Hz or 100 Hz when the system frequency is 50 Hz) when entered
via the keypad or software; and the L30 will stop the transmission of reports. Note that 4 Hz is not allowed for an M-
class 50 Hz system).
•
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 given
application. 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 typically
based 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 a
user-selectable analog channel of the data frame. Up to 16 analog channels can be configured to send any FlexAnalog
value from the relay. Examples include frequency, rate of frequency change, active and reactive power, per phase or
three-phase power, power factor, temperature via RTD inputs, and THD. The configured analog values are sampled
concurrently with the synchrophasor instant and sent as 16-bit integer values.
•
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 a
user-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 1and
byte 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
normal
state
for each digital channel. These states are transmitted in configuration frames to the data concentrator.
