Active power-dependent adjustment of desired voltage value with 3
different desired values
The TAPCON® Dynamic Setpoint Control (TDSC) function is used to adapt
the desired voltage value depending on the measured active power. This al-
lows you to compensate for a voltage drop during increased load or an in-
crease in voltage due to a decentralized feed-in.
The device provides you with 3 different sets of parameters for this purpose.
Depending on the selection of the desired value 1, 2 or 3, the device uses
the parameter set 1, 2 or 3 for TDSC.
Depending on whether positive or negative active power is measured, the
desired value calculation is based on 2 linear equations (see example in dia-
gram below).
