Figure 368:
Operating area of 32Q-27 function
Quadrant II Generator produces active power, but draws reactive power (under-excited)
Quadrant III Generator produces both active and reactive power
The power direction can be reversed by setting
Pol reversal
to “True”.
Timer
Once activated by both Under voltage detection and Reactive power monitoring module,
the Timer activates the
PICKUP
output. The Timer characteristic is according to DT.
When the operation timer has reached the value set by
Trip delay time
, the
TRIP
output
is activated. If the fault disappears before the module operates, the Timer is reset
instantaneously.
The Timer calculates the start duration value
PICKUP_DUR
which indicates the
percentage ratio of the pickup situation and the set operating time. The value is available
through the Monitored data view.
Blocking logic
There are three operation modes in the blocking function. The operation modes are
controlled by the
BLOCK
input and the global setting
Configuration/System/Blocking
