SMA Power Plant Controller



Why is a power plant controller needed

> In big PV installation it is not possible to control the PV park behavior at the point of l (PCC) b lcommon coupling (PCC) by a single inverter

> The inverter usually has no information of the electrical conditions at the PCC> B tw th i t d th PCC w h di t f t l k> Between the inverter and the PCC we have distances of up to several km> Cables and transformer influences the electrical behavior between inverter and PCC

> A controller is needed to read actual values at the PCC, receives set points from a supervisory control ( l ) d l h

PCC

(utility) and controls the inverter




Operating modes for control> Modes for different control strategies

> U = const.> cos φ = const.> Characteristic curve Q(U)> Characteristic curve cos φ(P)

> In parallel: control of active powerd d P(f)> on demand or P(f)

> Timetable mode> Cascade control> Cascade control
