NOTE
Keep in mind that the parameter Number of target voltage cannot be influenced by way of the
settings group switching.
You can specify the target voltages (1 W1/2 to 4 W1/2) in primary, secondary, or in percent.
For the activation of the target voltage 1 to 4 via a binary input, you need a CFC chart.
Parameter: Target voltage 1 w1
•
Default setting (_:16351:112) Target voltage 1 w1 = 110.000 V
Parameter: Target voltage 1 w2
•
Default setting (_:16351:146) Target voltage 1 w2 = 110.000 V
Parameter: Target voltage 2 w1
•
Default setting (_:16351:165) Target voltage 2 w1 = 110.000 V
Parameter: Target voltage 2 w2
•
Default setting (_:16351:168) Target voltage 2 w2 = 110.000 V
Parameter: Target voltage 3 w1
•
Default setting (_:16351:166) Target voltage 3 w1 = 110.000 V
Parameter: Target voltage 3 w2
•
Default setting (_:16351:169) Target voltage 3 w2 = 110.000 V
Parameter: Target voltage 4 w1
•
Default setting (_:16351:167) Target voltage 4 w1 = 110.000 V
Parameter: Target voltage 4 w2
•
Default setting (_:16351:170) Target voltage 4 w2 = 110.000 V
Voltage Controller
Parameter: Bandwidth
•
Default setting (_:113) Bandwidth = 1.0 %
With the Bandwidth parameter, you specify the voltage range where no control action higher or lower is to
occur at the Target voltage 1. If the actual voltage is outside the bandwidth referenced to the Target
voltage 1, no correction takes place.
Calculation of the Bandwidth:
NOTE
When calculating the Bandwidth B, keep the maximum accepted voltage deviation in the electrical power
system and the tap voltage of the tap changer on the secondary side of the transformer in mind. Select the
bandwidths so that it is not passed through within an increment.
On the secondary side, the increment ∆V
sec
is not linear. The largest ∆V
max,sec
in an increment results with the
increment to the highest stage (smallest ratio) and with maximum power-system voltage on the primary side.
[fobdnvrz-150816, 1, en_US]
If the control deviation and the bandwidth are thus correlated, this results in a minimal bandwidth that is to be
set:
