System control circuit

Controlling ensures that the changes to the power data are compensated by
the PV systems on the way to the GCP (NS or MS) and the requested
requirements are implemented on the GCP.
•
The GCP controlling procedure is only active if the reactive power
procedure is selected.
For the correct function of the system control circuit, the following parameters
must be entered correctly.
•
In the area
Admin monitoring » Power Control » General configuration:
• Agreed connection power P
• Maximum agreed apparent power S
• Nominal voltage AC U
• Parameter model [transformer / no transformer] *
• Transformer nominal power [kVA] *
• Lower P
• Lower cos(ϕ)
• Upper Q
The upper Q
cos(ϕ)
manufacturer in one of the two fields is therefore not sufficient. If the
cursor leaves the field or if the enter key is pressed, the relevant other
field is updated.
•
In the area
Konfiguration » Anlagendaten (Configuration » System data), the
following data must be entered:
• Installed power [kW] *
Important! All the data must be correct. The data entered, in particular the
parameters highlighted with *, are elementary for the correct control.
Incorrectly entered data, incomplete target value queries or requested target
values outside the technically feasible range of the inverter(s) result in
control malfunctions.
