8.2.3.10 Exclusion mode
Exclusion mode is on when the value of the
Exclusion time
parameter is higher
than zero. During the exclusion mode, new triggerings are ignored if the triggering
reason is the same as in the previous recording. The
Exclusion time
parameter
controls how long the exclusion of triggerings of same type is active after a
triggering. The exclusion mode applies only 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 disturbance recorder, counting the
remaining exclusion time. The remaining exclusion time can be monitored with
the
Exclusion time rem
parameter (only visible via communication, IEC 61850 data
ExclTmRmn) of the corresponding analog or binary channel. The
Exclusion time rem
parameter counts downwards.
8.2.4 Configuration
The disturbance recorder can be configured with PCM600 or any tool supporting
the IEC 61850 standard.
RDRE1 should always be included in Application Configuration when the
disturbance recorder is used.
The disturbance recorder can be enabled or disabled with the
Operation
parameter
under the Configuration> Disturbance recorder> General menu.
One analog signal type of the protection relay can be mapped to each of the
analog channels of the disturbance recorder. The mapping is done in Application
Configuration in PCM600. The name of the analog channel is user-configurable.
It can be modified by defining a new name to the
Channel id text
parameter of
the corresponding analog channel.
Channel id text
can be edited in Application
Configuration by selecting the input channel and defining a new
Instance Name
for
the channel in the Object Properties window.
Any external or internal digital signal of the protection relay which can be
dynamically mapped can be connected to the binary channels of the disturbance
recorder. These signals can be, for example, the start and trip signals from
protection function blocks or the external binary inputs of the protection relay. The
connection is made with dynamic mapping to the binary channel of the disturbance
recorder using, for example, Signal Matrix of PCM600. It is also possible to connect
several digital signals to one binary channel of the disturbance recorder. In that
case, the signals can be combined with logical functions, for example AND and OR.
The name of the binary channel can be modified by defining a new name to the
Channel id text
parameter of the corresponding channel.
Channel id text
can be
edited in Application Configuration by selecting the input channel and defining a
new
Instance Name
for the channel in the Object Properties window.
The
Channel id text
parameter is used in COMTRADE configuration files
as a channel identifier.
