Fig. 56: Formula no. 3
On account of the definition of a voltage jump in pre-norm EN50549-2 and in VDE-AR-N 4120 and VDE-AR-N
4110, it is typically the case that another voltage jump is detected when the incident is at an end, when the
fault is rectified and when the voltage returns to a normal state. The result of this is that in an active operation
mode a dynamic grid support using a fast feeding of residual current remains active even after the incident has
passed and that reactive current is fed in according to the formulae (2) and (3). Dynamic grid support using fast
feeding of residual current is then deactivated after a configured minimum support time, usually 5 s.

Setting: Manual
All parameters can be configured independently.
Setting: Predefined zero current
Dynamic grid support active on account of immunity to interference and
zero current feed-in. During a voltage incident, the current in the in-
verter is reduced to zero.
All parameters are pre-configured, only the activation threshold for zero
current has to be configured.
Priority – Reactive cur-
rent limitation | Active
current priority Priority: Reactive current priority
Dynamic grid support active on account of immunity to interference and
fast feeding of residual current. The inverter feeds additional reactive
current according to the formulae (2) and (4).
Priority: Effective current priority
Dynamic grid support active on account of immunity to interference and
fast feeding of active current with dynamic reactive current. The in-
verter feeds in as much active power as available. If, as a result of this,
the maximum continuous current is not achieved, the device supplies
additional reactive current according to the formulae (2) and (4) up to
the limit of continuous current.

If one or more phase/phase or phase/neutral conductor voltages move
above the configured threshold, the inverter changes to zero current
mode. The total current is regulated to virtually zero.
Reference voltage
U< - U>
Nominal value of the phase/neutral conductor voltage used as a refer-
ence voltage for formula (1) and (3). Adjustable in the range from level 1
undervoltage protection to level 1 overvoltage protection.
