NOTE! Some cases when inductor size and losses are compensated, the zero load
voltage may need to decrease.
P2.2.6.4
Capacitor Size [%]
(ID1460)
AFE: This parameter defines the reactive current going to the LCL filter capacitor. It
compensates the LCL effect to the reactive current by adjusting the reactive current
reference internally. The inductor size is also added to compensation. If set correctly, the
power factor on the grid side will be 1.
Island and Micro Grid: Not used.
P2.2.6.5
Inductor Size
[%]
(ID1461)
AFE:
This parameter defines voltage losses in percentage of the nominal voltage at 100%
active current. This value is internally added to the reactive current reference thus giving
power factor 1 on the grid side, if set correctly together with Capacitor Size. The
transformer and feeding cables can be compensated by increasing this value.
Island and Micro Grid:
This parameter defines the voltage increase in percentage of the nominal voltage at
100% reactive current.
