• Reactive power: NO default regulation.
This section of the menu may be used to manage the supply of reactive
power into the grid. There are 5 possible types of management:
- No regulation: no regulation of reactive power. To enable this mode,
select Enable and then OK.
- Cos-phi xed: Sets the power rating to a xed value. To enable this
mode, select Enable and then OK.
When enabled, Set value will appear, allowing you to set the value of
Cos-Phi (as either Over or Under excited, from 1.000 to 0.800)
- Cos-phi = f(P): Power rating as a function of the active power supplied
by the inverter. To enable this mode, select Enable and then OK.
When it has been enabled, Load std curve will appear, allowing you to
set the following regulation curve:
The curve can be modied using the Aurora Manager LITE conguration
software
