Abstract
The main purpose of this thesis is to examine how the rotor current affects the output power and loss of a doubly-fed induction generator (DFIG) for wind energy conversion. The performance of the DFIG with
and without copper loss minimization was investigated.
In the experiment, feedback signals derived from the servo motor were first employed to calculate rotor angle which was essential for stator flux estimation. Then, the real and reactive power outputs of the DFIG were controlled by a rotor side inverter using a PI controller and the
pulse width modulation (PWM) technology.
Both experimental results and simulation results for DFIG with maximum power point tracking and copper loss minimization were presented. It was found from the results that less copper loss and more output power could be achieved by the copper loss minimization
algorithm.
