7. Normal operation
This setting is used to control real power based on the frequency excursion
This setting is applicable when Rule21 Standards are selected.
Start Freq: 60.50Hz
WGradient: 040%
Figure 7.41 Freq-Watt (1)
Start Freq: This is the frequency that active power reduction starts.
WGradient: This is the active power reduction rate in terms of the frequency.
Stop Freq: This is the frequency that stops the correction cycle.
Hysteresis: This indicates whether hysteresis is enabled.
