Maximum Power Control of DFIG Based Grid Connected Wind Turbine Generator System Muhammed Y. Worku, M.A. Abido   2018/04/20

Abstract

This paper presents a simulation model of variable speed wind turbine with a doubly fed induction generator developed in Matlab/simulink. Vector control of a doubly fed induction generator (DFIG) drive for variable speed wind power generation is described. A slip ring (wound rotor) induction
generator with back to back three phase PWM converter between its rotor and the grid forms the electrical system. A vector control scheme for the PWM converters results in independent control of
active and reactive power. Line (supply) voltage oriented reference frame has been used to independently control the active and reactive power. Results are provided at the end for subsynchronous and super-synchronous operation of the DFIG.
