Abstract
This paper describes a preliminary study of a 30 kW
doubly-fed induction generator (DFIG) used for wind turbine
applications. Wind represents a variable-speed intermittent
source of energy in nature and can be controlled to be a nearly
constant speed but variable-torque input to the wind turbine
using blade pitch angle regulation. Wind profile at the installation
site is investigated so as to derive parameterized wind speeds,
more importantly, the annual cubic-mean speed. This is taken
account into the machine design since the machine efficiency
varies with turbine mechanical inputs. By coordinating the loss
components, it is possible at the machine design stage to select the
maximum efficiency to be near the actual optimized load, in a
long run, to maximize the overall energy production of the
generator. The DFIG is modeled in Matlab with a vector control.
The total energy production is used as a key criterion to refine the
machine design.
