Abstract
The wind turbines based on Doubly Fed Induction
Generators (DFIG) represent almost the 60% of the installed
windpower worldwide. Nowadays most of the existing algorithms,
used for regulating the production of active and reactive power in
such systems, are based on control techniques that use rotational
reference frames theories, where the dq0 is maybe the most
popular. Despite of its good operation under balanced conditions
its behaviour depends on a good phase synchronization, otherwise
the different transformations cannot be performed with enough
guarantees. Of course this kind of response is becomming
insuficient, as far as the windpower penetration is increasing.
This paper will present a new control topology for DFIG, that
are connected using back to back inverters, that is able to
behave better in case of faulty grids. Besides some proposals
for improving the operation of the DFIG will be presented as
well. The aim of that part is to extend the possibilities that the
back to back inverters are able to offer to the generator system
by means of including new functionalities, as the active filtering
capability or the reduction of the flicker emission that will be
later discussed.
