Const. Q Abs - Fronius SnapINverter Serviceanleitung

Const. Q Abs

Constant specification of absolute reactive power in VAr
Setting range: -n - 0 - +n [VAr]
n = maximum reactive power that can be set depending on the respective inverter
Example:
Q
rel
Q = Reactive power [VAr]
P = Effective power [W]
S
n
cos φ = Power factor
Q
rel
Example for Fronius Galvo
= -n VAr
1
under-excited (inductive)
cos φ = -0,85
Q = -n VAr
rel
= Nominal apparent power [VA]
= Operative reactive power limit of the inverter [%]
over-excited (capacitive)
P
cos φ = +0,85
Q = +n VAr
Q
rel
Q = -n VAr
rel 1
