This paper develops a study of reduced-order
models for squirrel-cage induction generators (SCIG) used in
fixed-speed wind turbines (WTs). The squirrel-cage of these
generators must be modeled with a double-cage for accuracy
purposes. These proposed reduced-order models are valid for
unbalanced grid conditions (unsymmetrical faults), which
require flux and current decomposition into positive- and
negative-sequences. Three reduced-order models are obtained:
R2 model, where the derivative of the positive- and negativesequences
of the stator fluxes are neglected (the usual approach
in the literature); R1 model, where the derivative of the negativesequence
of the rotor fluxes are also neglected (proposed model);
and R0 model, where all the stator and rotor fluxes are neglected
(steady-state electrical model). The analytical models are
validated with simulations carried out in MATLABTM and with
experimental tests. The results show that R1 model (proposed
model) shows a good performance (similar to the full-order
model) under unbalanced conditions. [-]
