Abstract

Doubly-Fed Induction Generator(DFIG) is adequate to maximize the energy capture from wind energy, whereby the turbine speed can be adjusted to a speed, at which a rated tip speed ratio be kept. In this paper, a power analysis for DFIG and its characteristics of power flow in grid-connected operation, are dealt with in speed range of super- and sub-synchronous region. In a test of the machine, whereby a doubly excited circuit configuration in stator as well as rotor with back to back PWM inverter have been equipped, a constant input torque is given and in that condition, power new in stator and rotor circuit have been measured and compared with theoretical value. Furthermore, the power factor in stator and rotor circuit have been examined.
