Dynamic grid support (Fault Ride Through)
A generator plant's ability to remain immune to voltage dips and voltage swells in the supply system is
a key element in establishing a reliable energy supply. Immunity to interference ensures that brief dis-
ruptions do not result in a loss of generation capacity in a larger area of the interconnected grid. Grid
support by way of fast fault current injection also limits the spatial extent of the incident.
With its dynamic grid support by way of immunity, the device has this characteristic. The ability to re-
main on the grid is particularly relevant. The protective settings also determine the device's ability to
remain on the grid or not. Protective settings take the upper hand over the capacity of immunity to in-
terference.

10.3.1 Dynamic grid support by way of immunity to interference

Interference immunity against undervoltage
Voltage drop above the limit curve in can be overcome without the need for shutdown from the grid.
The feed-in power remains constantly within the limits of the maximum continuous current of the inver-
ter.
If a reduction in power occurs, the power is brought back up to the pre-fault level within 100 ms of the
voltage returning.

Dynamic gradient maximum frequency:
If dynamic gradient mode is activated, the gradient is calculated in order
to guarantee a linear power adjustment and reach the maximum char-
ging power if the frequency rises to the maximum configured frequency.
Dynamic gradient minimum frequency:
If dynamic gradient mode is activated, the gradient is calculated in order
to guarantee a linear power adjustment and reach the maximum feed-in
power if the frequency drops to the minimum configured frequency.
Determines the dynamic behaviour in the event of a change in the acti-
ve power limit. In the event of a change in frequency, the active power
is altered subject to a PT-1 characteristic curve using a settling time of 5
Tau.
The settling time is overlaid with the increasing and decreasing gradient.
F Specify the increasing and decreasing output gradient.
Specifies the dynamic response on changing the active power for power
increase and decrease. With a voltage change, the active power is chan-
ged with the specified gradient.
Note: The gradient is overlaid with the settling time.
