Technical Manual
exclusion of triggerings of same type is active after a triggering. The exclusion mode only
applies to the analog and binary channel triggerings, not to periodic and manual
triggerings.
When the value set with the
Exclusion time
parameter is zero, the exclusion mode is
disabled and there are no restrictions on the triggering types of the successive recordings.
The exclusion time setting is global for all inputs, but there is an individual counter for
each analog and binary channel of the digital fault recorder, counting the remaining
exclusion time. The user can monitor the remaining exclusion time with the
Exclusion time
rem
parameter of the corresponding analog or binary channel. The
Exclusion time rem
parameter counts downwards.
9.1.2
Configuration
The user can configure the digital fault recorder with the PCM600 tool or any tool
supporting the IEC 61850 standard.
The user can enable or disable the digital fault recorder with the
Operation
parameter
under the
Configuration/Digital fault recorder/General
menu.
Analog channels are fixed except channel 4 which is selectable based on the Ground CT
option. The name of the analog channel is user-configurable. The user can modify it by
writing the new name to the
Channel id text
parameter of the corresponding analog
channel.
Any external or internal digital signal of the IED which can be dynamically mapped can
be connected to the binary channels of the digital fault recorder.These signals can be, for
example, the pickup and trip signals from protection function blocks or the external digital
inputs of the IED. The connection is made with dynamic mapping to the binary channel of
the digital fault recorder using SMT of PCM600. It is also possible to connect several
digital signals to one binary channel of the digital fault recorder. In that case, the signals
can be combined with logical functions, for example AND and OR. The user can configure
the name of the binary channel and modify it by writing the new name to the
Channel id
text
parameter of the corresponding binary channel.
Note that the
Channel id text
parameter is used in COMTRADE configuration files as a
channel identifier.
The recording always contains all binary channels of the digital fault recorder. If one of
the binary channels is disabled, the recorded state of the channel is continuously FALSE
and the state changes of the corresponding channel are not recorded. The corresponding
channel name for disabled binary channels in the COMTRADE configuration file is
Unused BI.
To enable or disable a binary channel of the digital fault recorder, the user can set the
Operation
parameter of the corresponding binary channel to the values Enable or Disable.
The states of manual triggering and periodic triggering are not included in the recording,
but they create a state change to the
Periodic triggering
and
Manual triggering
status
parameters, which in turn create events.
