Low-Speed Sensorless Control for Wind Turbine System

摘要

In the propose of the work, we concerns the elaboration an efficient and robust control of active and reactive power by the use the PI regulators control (FOC) a power converters directly connected to the stator and the rotor of a Doubly Fed Induction Generator (DFIG) system incorporated in a wind turbine to improve the performance of a speed wind turbine. In the aim to assess the performance and dynamics of the wind system, for the different test speeds of the wind, we are interested in the modeling, development and control of the wind system. Initially, a control strategy of the MPPT-DFIG is presented. Therefore, the aim is the study and implementation of the new control technique for wind systems. This control technique is based on the orientation control of the flow rotor to DFIG. Finally, the control simulation results are simulated on the environment Matlab/Simulink. A very detailed analysis of simulation results of wind conversion chain system is performed with the objective to evaluate and optimize the performance of the proposed system.
