Variable speed wind turbine with doubly-fed induction generator (DFIG) is gradually replacing fixed speed one with squirrel cage induction generator (SCIG) in wind power applications. It is worthwhile to compare these two generators with respect to operating principle, controlling ability, etc. This paper concentrates on analyzing active/reactive power relationship in steady-state between DFIG and SCIG by simulation on MATLAB. Another key task investigated in this paper is comparison of electromechanical torque-slip characteristics between DFIG and SCIG with several different conditions such as interconnecting network strength and type, generator terminal voltage, and rotor resistance. Comparison results verify that DFIG has distinct features over SCIG.
