Power Control of a Doubly Fed Induction Wind Generator employing a Takagi-Sugeno Fuzzy Logic Controller

This paper presents the active and reactive power control of the Doubly Fed Induction Generator employing Fuzzy Logic for a wind power generation system. The proposed controller is a Fuzzy Logic Controller Takagi-Sugeno type which determines the rotor voltage by a set of rules base defined by a linear combination of the rotor current's error membership sets, reducing the structure complexity of the control system and consequently a lower computational cost is achieved. Additionally, it is easy to implement on a digital signal processing board when it's compared with other controllers such as the Fuzzy Mamdani type. The control system is accomplished using the Stator Flux Oriented Control with Space Vector Modulation technique and a computer simulation is implemented in Matlab/Simulink. The results indicates that the TS FLC could be an interesting alternative to conventional controllers in the power control of the DFIG during normal operation conditions.
