Behavior of DFIG with Direct Torque Controller at Unbalanced and Distorted Grid Voltage Conditions

This project focuses on the enhanced and development of the direct torque controller of doubly fed induction generator (DFIG) with unbalanced and distorted grid voltage conditions. Real, reactive power and electromagnetic torque are improved by using the design and development of Analytical model, Finite Element analysis (FEM), Direct Torque Controller with active Crowbar circuit and network side converter. Finally fundamental, fifth and seventh order harmonics are removed by using Fast Fourier transform (FFT) and also determine Total harmonic distortion (THD) and Individual harmonic distortion (IHD). The simulation result is exposed using power system computer aided design (PSCAD).
