Each protection element generates its own pickup and trip signals, which are automatically passed onto the
»Prot«
module where the phase based and general (collective) pickup and trip signals are generated. The
»Prot« module
serves as a top level and a common place to group all pickups and trips from each individual protection element.
For instance, »P
ROT
.P
ICKUP
P
HASE
A« is the phase A pickup signal OR-ed from all protection elements; »P
ROT
.T
RIP
P
HASE
A« is the phase A trip signal OR-ed from all protection elements; »P
ROT
.P
ICKUP
« is the collective pickup signal OR-ed
from all protection elements; Prot.Trip is the collective Trip signal OR-ed from all protection elements, and etc. The
Tripping commands of the protection elements have to be fed to the
»Bkr Manager« module for further trip request
processing.
The tripping commands are executed by the
»Bkr Manager«
module.
Tripping commands have to be assigned to a breaker. The Breaker Manager will
issue the trip command to the breaker.
If a protection element is activated and respectively decides to trip, two pickup signals will be created.
1.
The module or the protection element issues an pickup/alarm (e.g.: »50P[1].P
ICKUP
« or »50P[1].T
RIP
«).
2. The master
»Prot« module
collects/summarizes the signals and issues
a pickup/alarm or
a trip
signal
»P
ROT
.P
ICKUP
« »P
ROT
.T
RIP
«.
