5.2.2 Power flow control mode

In power flow control mode (Fix Power), when in parallel with another source the SFC has the 
ability to provide fixed P and Q power flow on the output. This is used when interfacing genera-
tors to a grid where power flow to and from the grid must be controlled.

Setpoints for both real power (P) and reactive power (Q) can be set.

User interface 

The primary user interface is via a door mounted touch screen Graphical Display Module (GDM). 
The display is a 10” resistive touchscreen with a user-friendly intuitive interface.

The integrated navigation screen gives easy accessibility to any information on the SureWave 
SFC, it shows the system status and provides access to the operating parameters and event his-
tory. The mimic diagram gives the users a clear view of the status of the system.
