This paper deals with the implementation of wind turbine driven by Doubly Fed Induction Generator (DFIG) using Matlab/Simulink and Labview. Here, Matlab/simulink readily deals with the Second Order Sliding Mode (SOSM) controller with DFIG wind turbine. SOSM control is used in order to obtain finite reaching time. Maximum power can be obtained by directly tracking the torque obtained. By SOSM controller, Maximum power extraction can be done with reduced mechanical stresses. In conventional methods due to failure in accuracies optimal power extraction is not done. This can be overcome by using SOSM control which will allow tracking DFIG torque directly for extracting maximum power. Turbine tip speed ratio is considered in doing so. The stator of the machine is directly connected to the power grid while the rotor is controlled by an inverter. Labview here is used for graphical representation of the desired output. Labview programs are integrated with DFIG wind turbine in order to acquire, analyze and displaying the data. In this paper, implementation of a DFIG based wind turbine is done and it is integrated with Labview. The results obtained here readily implies where the maximum power is extracted.
