Improving the Fault Ride Through capability (FRT)
of Doubly Fed Induction Generators (DFIG) in wind power
applications is a very important challenge for wind power
industry. The mathematical models of such generators permit to
analyze their response under generic conditions. However, their
mathematical complexity does not contribute to simplify the
analysis of the system under transient conditions, and hence do
not help to find straight-forward solutions to enhance their FRT.
This paper presents a simplified model of the DFIG, that has
been extracted from the classical fifth order model, which is able
to estimate accurately the behavior of the system while reduces
significantly its complexity. In this work, the mathematical
deduction of this model will be presented and simulations and
experimental results will be shown, in order to demonstrate the
accuracy and reliability of the proposed algorithm.
