7.3.12.11 Activating/deactivating regulator blocking with negative active power
When regulator blocking is activated, the control is blocked if a negative active
power flow is detected. However, this is only possible if the current transfor-
mer connection is connected and correctly set. When regulator blocking is
deactivated, then the sign of the active power does not affect the regulation.
To activate/deactivate regulator blocking, proceed as follows:
1. > Control Parameters > Com-
pensation > 8x
.
<08> neg. active power block.
2. Press
or to to activate
(ON)/deactivate (OFF) blocking.
3. Press
.
Blocking the regulator with negative active power
is activated/deactivated.
7.3.13 Compensation
The quality of the energy supply depends not only on the voltage at the bus-
bar of the supply transformer (measurement value V), but also the voltage di-
rectly at the equipment.
In some cases the line impedance - of the cables or overhead lines - needs to
be taken into account for voltage regulation. A significant (load-dependent)
voltage drop can occur in these lines. This voltage drop is dependent on the
following factors at the consumer:
 Impedance (apparent resistance)
 Cable
 Electrical current
 Phase angle φ
The device has two possible ways of balancing a load-related voltage drop
between the transformer and the consumer:
 Line drop compensation
 Z compensation
