Reactive Power - Danfoss TLX 6k Serie Manual Del Usuario

2.2. Reactive Power

Standard reactive power settings are configured with the grid code. Changes to a standard grid
code will generate the grid code 'custom'.
PF(P)
The inverter will generate a variable level of reactive power depending on the output power.
The relationship between reactive power and active power is entered as a setpoint curve. The
setpoint curve can consist of up to 9 points with the reactive power in the range from: 0.8 un-
der-excited to 0.8 over-excited.
Illustration 2.1: Example of Default Setpoint Curve for Germany LV: Installations less than or equal to 13.8
kVA
For some grid codes, the setpoint curve behaviour is only activated over a certain grid voltage
level.
Italy
To ensure that sufficient current is always available to supply the required reactive power, the
inverter must allocate spare capacity. In these cases, the inverter active power output is limited
to: [name plate rating] x [cos(φ) required]
Example: 6 kVA x 0.9 = 5.4 kW (see AC power rating table)
To override this value, set reactive power settings via the web interface, at
Plant level: [Setup → Grid Management]
To remove this allocation of spare capacity, disable reactive power.
