Configuration of the Load Shedding
Call up menu [Protection Para\Set[x]\Intercon-Prot\UFLS]
Within menu [Protection Para\Set[x]\Intercon-Prot\UFLS] you can define variant respectively the active power area
that will not lead to a load shedding (load shedding blocked) in case of under frequency.
The active power flow direction can be determined by two different methods. Please select the
UFLS method:
•
Power Angle Supervision (Method 1)
•
Pure Active Power Supervision (Method 2)
•
External (Method 4)
Method 1: Power Angle Supervision
A load shedding during under frequency will be blocked, if the active power is within the area limited by the power
angle.
The diagram above is in compliance with FNN
5
. This diagram shows the
blocking area within the generator arrow flow system.
