Active power regulation

Dynamics / accuracy
In all of the control methods described below the specified target value at the inverter's connection terminals is adjusted
using a stationary deviation of the reactive power of maximum 2% S

Action in this menu/meaning
In addition to configuring the dynamic behaviour using the setting time
corresponding to a first-order filter, the reactive power setting can be
determined by a maximum gradient - this means the maximum change
in the reactive power per time period.

Settling time in the event of an abrupt change in the reactive power tar-
get value (e.g. caused by a voltage jump). The transient behaviour cor-
responds to a first-order filter (PT-1) with setting time = 5 Tau.
2000 [ms]
NOTE: The settling time is overlaid with the increasing and decreasing
gradient.
In the event of a significant voltage deviation, the maximum reactive
power adjustment range can be limited by a minimum cos ϕ in order to
prevent an excessive reactive power supply and, as a result, a significant
0 /
reduction in the maximum active power that can be fed in.
Minimum cos ϕ in overexcited operating mode (in-feed).
Minimum cos ϕ in underexcited operating mode (in-feed).
Minimum cos ϕ in overexcited operating mode (charge).
Minimum cos ϕ in underexcited operating mode (charge).
P-priority can be selected as an alternative to the standard setting Q-pri-
ority. When it comes to P-priority, the reactive power adjustment range
is limited subject to the limited apparent power of the inverter and the
active power that is currently available and fed in.
Up to four characteristic curves can be configured independently and
one of them can be activated for regulation each time.
Specify the number of nodes for the Q(U) characteristic curve.
Power of the node as a percentage of the maximum power.
For the 1st node, the power must be 0%; for the last node, the power
must be 100%. The power values of the nodes must increase continu-
ously.
