Modeling and control of active and reactive powers of wind energy conversion system in variable speed based on DFIG
Main Article Content
Abstract
This article describes the modeling and control of wind conversion chain system based on DFIG in variable speed. In fact, the aerodynamic and the electrical models of the wind conversion chain are presented and discussed. Also, the adjustment of active and reactive power is opted in order to ensure optimal operation. For this purpose, a vector control method is applied to ensure a decoupling of its electromechanical quantities. These two parts are developed and programmed in Matlab/Simulink. Some simulation results obtained for the variable-speed operation in hypo- and hyper synchronous modes studied to validate the command will be presented and analyzed.
