Abdelhadi El Moudden, Abdelali Aarib, Abdelhamid Hmidat . The Converter Command for the Doubly-Fed Induction Generator with Variable Speed used in the Wind Power Production. International Journal of Applied Information Systems. 8, 6 ( April 2015), 32-39. DOI=10.5120/ijais15-451335
This paper presents a global and optimal environment of the electro-mechanical conversion chain using the doubly-fed induction generator (DFIG) in wind turbines having an active power in the stator of the order of Megawatts (MW). The establishment of the diverse models of electric parameters and the development of the methodological tools available in the environment MATLAB/Simulink are interpreted . The main components of the chain of conversion are modelled and the DFIG makes the object of a particular attention as for its sizing. Analytical and numerical methods are proposed to carry out the optimal design of the entire drive including DFIG, the multiplier mechanical speed and power converter. The implementation of the environment is illustrated by solutions associated with different overall design requirement specifications including the distribution of active and reactive stator powers on the DFIG . The results show that there are different solutions as the original topology is presented dimensionally. The goal is to optimize the quality of energy generated by wind by manipulating the sizes of the active and reactive power as needed. The approach of the control of converters AC-DC-AC is used . The method used is to adjust the stator reactive power so that the machine side converter and inverter supply side will be bidirectional, to adjust the wind speed to that of the doubly-fed induction generator, which is very favourable for energy production in wind systems. The results of the simulation will be presented in MATLAB/Simulink, as well as related interpretations.
