Inverter reactive power setting: running mode
The inverter may be required to participate to voltage control by means of production and absorption of reactive power.
There are seven reactive power control modes. Only one mode may be active at a time.
The inverter acts as a load from the perspective of the grid according to the country standard. This means the inverter
operation in Quadrant II (under-excited) or III (over-excited) as below.
Over-excited reactive power also known as Capacitive reactive power or Leading power factor.
Under-excited reactive power also known as Inductive reactive power or Lagging power factor.
Tap ‘Reactive power control mode’ to choose the mode. The ‘Time constant
3(τ)
’ should be set first. The reactive power
change maybe required to correspond with a first order filter. The ‘Time constant
3(τ)
’ is three time constant of the filter
and is the time until 95% of the nominal value is reached.
