Parameters and/or model assumptions
Synchronous generators
Parameters are in per unit on base values of 900 MVA, 20 kV, and 60 Hz ,,,,,,,,,,,,,, s (for G2), (for G3 and G4),
Transmission lines
Parameters are in per unit on base values of 100 MVA and 20 kV. The line lengths are as shown in Figure 5. ,,
Transformers
Rating: 900 MVA, 20/230 kV, off-nominal tap ratio = 1
Loads
Represented using static models with the active component modeled as constant current and the reactive components as constant impedance.
Excitor
,
PSS
The reference settings of the PSS are as follows:,,,,,
DFIG
Rating: 2 MVA, 0.69 kV. The DFIG parameters in per unit are as follows:,,, The parameters for the DFIG control system are given in Ref. [23].The DFIG is connected to the main step-up transformer through a 0.69/20 kV transformer with and .
