8.3.3 Frequency Dependant Power Reduction Enable On
Grid Over Frequency
Figure 50: Grid over frequency
PM : Instantaneously Available Power
ΔP : Power Reduction (Power Reduction Gradient Level)
This function controls active power which is proportional to Grid frequency increase. As you can see in the picture,
active power need to be restricted if grid frequency is over 50.2 Hz. PM (Instantaneously available power) decrea-
ses with 40 %/Hz slope and it can be restorable if grid frequency is less than 50.05 Hz.
When this function is activated, the protection function for “Grid Over Frequency Level 1” is disabled and the pro-
tection function for “Grid Over Frequency Level 2 and “Grid Over Frequency Level 3” is enabled.
