As you can see in the above picture, this Q(V) Control function is for the reactive power infusion even if grid is in
normal range (90 ~ 110 %). Dead band rage is U
Target
± 1 %.
Here, you can calculate slope K Factor for Q(U) Control using an equation ΔQ/ΔU=K Factor, and the variables which
are ΔQ=cos(Phi)=0.95, Phi=18.2° and sin(Phi)=0.31. ΔU is the voltage diff erence between the measured voltage and
the specifi ed parameter target voltage as a p.u. Therefore, you can decide slope k factor. For example, if you want
to infuse ΔQ at U
Target
± 5 % range and U

=U

, the K value would be calculated as 0.31/0.05=6.2. The rage of ΔU is
calculated from the end of the dead band.
