Figure 7.31.: cosφ(P) graph
There are two possible curves dened in the cosφ(P) graph, curve A in blue (the default) and
curve B in red. Pn = nominal power
Curve A (in blue on Figure 7.31)
A is identied from Plock-out = value from local grid operator and cosφ = 1
B is identied from Plock-in = value from local grid operator and cosφ = 1
C is identied from P = Pn and cos = cosφmax
Curve B (in red on Figure 7.31)
A is identied from Plock-out = P = value from local grid operator and cosφ = 1
B is identied from Plock-in = value from local grid operator and cosφ = 1
C is identied from P = Pn and cos = cosφmax
Important:
When Plock-out = Plock-in then Curve B will be followed.
When Plock-out is ≠ Plock-in then Curve A will be followed.
