S. Sasikumar, S. Singaravelu . Improved Performance of Wind-driven Isolated Induction Generators by Six-phase Operation. International Journal of Computer Applications. 50, 13 ( July 2012), 28-32. DOI=10.5120/7833-1097
Abstract
This paper describes a new, generalized and efficient steady-state model for the performance analysis of isolated six-phase induction generators. The mathematical model is formed directly from the equivalent circuit of six-phase induction generator by nodal admittance method. The proposed model is very simple which completely avoids lengthy derivations of non linear equations. The model results in matrix form so that inclusion or elimination of any equivalent circuit elements can be easily achieved. Also, this model is flexible to find any combination of unknown quantities of the equivalent circuit. The matrix equation is solved by genetic algorithm to determine the steady-state performance of isolated six-phase induction generator (ISPIG). To validate the improvement of performance by six-phase operation, the experimental and theoretical results were compared with three-phase operation. In addition, the winding diagram of the six-phase / three-phase induction generator which is used as a prototype model for the experimental study is also presented
