5.9.2 Frequency-dependent Active Power Limitation P(f)
Activating this function enables active power limitation P depending on the grid frequency f
AC
. The
process used complies with the Medium Voltage Regulation valid in Germany. However, the settings
can also be adjusted to the requirements of other countries or utility operators by means of software
parameters.
The "P-WCtlHzMod" parameter allows you to select the frequency-dependent active power limitation
P(f). 2 settings can be selected.
This process is deactivated on delivery.
