Identification of Doubly Fed Induction Generator based Wind Energy Conversion System using piecewise-linear Hammerstein Wiener model

The aim of this paper is to present a piecewise-linear Hammerstein Wiener model for the identification of variable speed Wind Energy Conversion System driven by Doubly Fed Induction Generator (DFIG). The subsystems of the wind energy conversion systems are identified individually using non linear system identification technique. The complete wind energy conversion system is modeled in matlab simulink environment and its properties are analyzed. The model is developed such that it can be suited for all types of induction generator configurations and it can also be used to study the steady state and transient state performances of Wind energy conversion system.
