9.2.2 Harmonics controller
Description
Harmonics in the supply voltage cause harmonics in the line currents. Current harmonics
can be reduced by activating the harmonics controller.
Example: setting the harmonics controller
The 5th and 7th harmonic are to be compensated:
Table 9- 1 Sample parameters for the harmonics controller
Index p3624 Infeed harmonics controller
order
p3625 scaling
[0] 5 100 %
[1] 7 100 %
0% scaling means that the harmonics controller has been deactivated.
100 % scaling means that the harmonics controller has been activated with standard gain.
The phase currents in parameter p0069[0...2] (U, V, W) can be verified using the STARTER
trace function.
