The "Q-VArTmsSpnt" parameter determines the delay time after which the calculated reactive power
setpoint is actively used.
In order to prevent several systems with this function from influencing each other, the "Q-VArTmsVtg"
parameter can be used to set a delay time. This delay time indicates for how long a voltage change
must be pending before a change in reactive power output will result. This allows several systems to
alternately regulate the grid voltage at the grid connection joint.
The "Q-EnaTmsVtg" parameter can be used to switch the delay time on and off.
