| Abstract | ||||
| This paper aims to develop a method of field orientation scheme for controlling both active and reactive powers of a DFIG (double fed induction generator) driven by a wind turbine. The controlled system consists of a wind turbine that drives a DFIG connected to the utility grid through AC-DC-AC link. The control method is based on the theory of controlling the de and qe axes components of voltage and current for both rotor side and line side converters using PI controllers. The main control objective is to regulate the dc link voltage for operating at the maximum available wind power. A mathematical dynamic model of a DFIG driven by a wind turbine system is presented. Digital simulation has been carried out in order to evaluate the effectiveness of the proposed system. The results confirm that good steady state and dynamic performances of the proposed system has been achieved under different types of wind speed variations. | ||||
