Parameter tting will facilitate model validation of the generic dynamic model for type-3
WTGs. In this thesis, a test system including a single 1.5 MW DFIG has been built and
tested in the PSCAD/EMTDC environment for dynamic responses. The data generated
during these tests have been used as measurements for the parameter tting which is
carried out using the unscented Kalman lter. Two variations of the generic type-3
WTG model (the detailed model and the simpli ed model) have been compared and
used for parameter estimation. The detailed model is able to capture the dynamics
caused by the converter and thus has been used for parameter tting when inputs are
from a fault scenario. On the other hand, the simpli ed model works well for parameter
tting when a wind speed disturbance is of interest. Given measurements from PSCAD,
the estimated parameters using both models are indeed improvements compared to the
original belief of the parameters in terms of prediction error.
