Abstract

This paper deals with characteristics analysis of Doubly-Fed Induction Generator (DFIG) in the supersynchronous speed regions. by control of voltage fed to the rotor using for bidirection control. This rotor voltage is controlled by con troll of inverter switching frequency and fire angle. Characteristics of DFIG is analyzed by steady-state algebraic equations of the equivalent circuit using numerical analysis. And it is compared with results of experiment. Consequently, this paper presented to find the optimal magnitude of voltage fed to the rotor for maximum power and PF, using result of characteristics analysis.
