Setting the bandstop filters
Because the same filter algorithms are involved, the settings of the bandstop filters are
always comparable with the settings of the current setpoint filters (see Section Current
setpoint filter (Page 103)).
To prevent resonance effects for nets with low short-circuit power (small RSC), a bandstop
filter (with defined notch depth) for approx. 0.25-fold controller frequency (see p0115) is
chosen typically. Appropriate values for the attenuation are preset for the numerator and the
denominator. Only the natural frequencies for the numerator and the denominator may need
to be adapted.
You can configure the bandstop filters for the Active Infeed using the following parameters:
● Negative phase-sequence system control (p3639 ff)
● Fixed setpoints (p2900 ff)
● Output voltage setpoint filter; activation with p5200.0 = 1
● Actual current value filter; activation with p5200.2 = 1
● Vdc actual value filter; activation with p1656.4 = 1
