Feed In Active Power level (P4) [G268]
Feed in active power (P4) level at which specified Q4 is
supplied.
Filter Time Constant On Active Power
Calculations [G269]
Calculated feed in active power (P) used for Q(P) support
has a first order filter. Time constant for that first order filter
can be configured here. This is common time constant for
all the active power levels i.e. P1, P2, P3 and P4.
Cos Φ control as a function of feed in
active power Cos
Φ (P) [G27]
Displacement power factor (CosΦ) at the terminals of AFE/
AFG can also be configured as a function of feed in active
power. Characteristics of displacement power factor (CosΦ)
as a function of feed in active power can be configured using
four configurable points. For details read section Reactive
power (Q) support, section 7.17.2. In this menu, settings
related to CosΦ -P characteristic curve can be configured.
Displacement power factor (CosΦ1) At
Active Power Level (P1) [G271]
Desired displacement power factor (CosΦ1) at calculated
feed in active power (P1) level.
Feed In Active Power level (P1) [G272]
Feed in active power (P1) level at which specified CosΦ1 is
maintained.
Displacement power factor (CosΦ2) At
Active Power Level (P2) [G273]
Desired displacement power factor (CosΦ2) at calculated
feed in active power (P2) level.
Feed In Active Power level (P2) [G274]
Feed in active power (P2) level at which specified CosΦ2 is
maintained.
Displacement power factor (CosΦ3) At
Active Power Level (P3) [G275]
Desired displacement power factor (CosΦ3) at calculated
feed in active power (P3) level.
