EXPERIMENTAL INVESTIGATION OF SELF-EXCITED INDUCTION GENERATOR FOR INSULATED WIND TURBINE

Abstract

The use of induction machine in autonomous operating mode of wind turbine generators is very appreciated in many applications for economic, logistic and technical issues. However, the induction machine model, which is naturally nonlinear, becomes more complicated with the addition of external capacitive bank for the self-excitation of the machine. The present paper provides a theoretical and experimental investigation of a self-excited induction generator (SEIG) behavior for various connection topologies by considering the machine magnetic saturation. A good agreement between simulation and experimental result is obtained from the benchmark test which includes various balanced and unbalanced loads with and without power convert
