Abstract:
Doubly Fed Induction Generator is an attractive solution in variable wind turbines[1, 2] because of its features like lessening losses, minimum cost, an improved efficiency and power control capabilities[2]. Traditionally the control is based on PI controller which is advisable just for linear systems. However, wind turbines components work as nonlinear systems where electromechanical parameters change frequently [3], thus, a SOMC is proposed and then a modest function to smooth control signal is introduced which will improve power fineness, minimize the chattering and ameliorate respond time, deal with grid requirements. Matlab tests are introduced and compared.
