23�3�3 Fixed reactive power in Var

Reactive Power Management

This function allows the connected inverters to generate a certain reactive power in Var for a definable

period of time.

Procedure:

•

Select Fixed reactive power in Var.

•

Activate the interfaces.

•

Enter the from (time).

•

Enter the Reactive power for this time period.

•

Check the box Inductive/under-excited for reactive power.

•

If necessary, enter additional times and the accompanying reactive power

•

SAVE settings.

If a certain reactive power in Var must be supplied for 24 hours, the time 00:00 as well as the value in Var

have to be entered in the first line along with checking the Inductive box. The other lines must also be filled

with 00:00. It is not necessary to enter reactive power.

Reductions

The following configuration options are available in the Reductions section.

•

Max.cos(phi)inductive/underexcitedandmax.cos(phi)capacitive/over-excited:

A maximum shift factor can be defined wit this the reduction. With this, it can be that less reactive

power is fed-in into the grid than allowed in the partial load range in order to maintain the shift

factor limits.

Note

Entering zero as the value deactivates the particular limit.
