In the study of the dynamical behavior of doublyfed
induction generators (DFIG), for wind power applications,
the use of reduced order models is useful in order to design
specific control strategies for wind power plants as well as to
obtain lightweight computing simulations. Within this field this
paper presents a new dynamic model for wind turbines, based
on DFIG, able of representing accurately its behavior during
both the steady state and the transient of the grid voltage. As it
will be proven this model permits to perform an accurate
analysis of the system when there is a voltage dip in the grid. In
the following a theoretical study of this model will be carried out
and the accuracy of its performance will be tested under
different conditions, by means of PSCAD/EMTDC simulations,
in order to show its reliability. Finally the reliability of the
simplified model will be tested in a scaled experimental setup.
