With the P, Q sign parameter in the function block General, the sign of the following measured values
of the respective function group can be inverted (see chapter
the Function, section Inversion of Power-Related Measured and Statistical Values):
Active power (total): P total
Active power (phase-related): P
Reactive power (total): Q total
Reactive power (phase-related): Q
Capacitor-Bank Data (Side-Dependent)
The capacitor-bank data characterizes the data of the capacitor bank to be protected. The side-dependent
capacitor-bank data applies to all of the functions in the Capacitor bank side function group.
Output Logic
The output logic treats the pickup and trip signals of the protection and supervision functions in the function
group separately. Pickup logic and output logic are each assigned to the signals. The pickup and output logic
generate the overarching indications (group indications) of the function group. These group indications are
transferred via the Protection information interface to the Circuit-breaker function group and are processed
further there.
The pickup and operate indications of the protection and supervision functions in the Capacitor bank side
function group are combined into one group indication using the following numbers and outputs.
