The Task
Managing unpredictable disturbances –
which arrive with little or no warning and
require accurate decisions and operator
actions within a matter of seconds –
is probably the most difficult and expensive
part of operating a power plant. In certain
cases, an automatic shutdown can occur
if the response is incorrect or too slow.
To solve this problem, it is necessary to
filter out emerging disturbances that can
cause a plant trip from the general stream
of messages, display them separately, and
flag them both acoustically and optically.
Operators also need clear instructions
in order to facilitate quick and accurate
reactions, even when working under time
pressure.
displaying them separately. The operator is
then notified of the trip-relevant messages
both optically and acoustically.
The Trip Stop button displays an alarm
in very critical cases when there is no
forewarning of a trip but rather a sudden
disturbance demanding an immediate
response. The operator has only seconds
to take action, so the Trip Stop button
comes with concise predefined instructions
for trip avoidance. This makes it possible
to resolve the situation with a single
mouse click in the associated Faceplate.
By paying attention to these two selection
buttons, operators have everything
important for trip avoidance at their
fingertips. As the most advanced type
of alarm focusing and trip avoidance
available, this filtering method can
increase the operator’s efficiency and
effectiveness – especially when it matters
the most.
Our Solution
Trip Stop buttons add an extra alarm class
to SPPA-T3000. Two new selection buttons
in the Upper Frame – “Trip Warning” and
“Trip Stop” – help operators recognize
and manage disturbances that have the
potential to cause a trip.
The “Trip Warning” selection button evaluates trip-relevant scenarios and generates
warnings that need priority attention from
the operator in order to avoid trips. This
entails analyzing disturbances affecting
the core components, filtering them out
of the general stream of messages, and

Trip Warning (TW) and Trip Stop (TS)
The two selection buttons define a new category
of alarm class. By providing intelligent alarm filtering
and instructions in the event of a critical alarm,
they make the operator’s job noticeably easier in
day-to-day operation, thereby increasing efficiency
and effectiveness.

Trip Warning (TW)
Only trip-relevant warnings that need

A modern form of user guidance, this
intelligent alarm focusing method helps
the operator to handle critical situations

Trip Stop (TS)
This button provides user guidance for
urgent alarm events. Clear instructions,
clear Faceplates, and clear guidance:
the key assets for trip avoidance.
