Steady state modeling and fuzzy logic based analysis of wind driven single phase induction generators

This paper describes a new generalized and efficient model using graph theory and fuzzy logic based steady state analysis of wind driven single phase single winding self-excited induction generator (SEIG) with or without series compensation. Steady state generalized model of single phase SEIG is formulated using nodal admittance method based on graph theory. This dispenses with tedious work of segregating real and imaginary components of the complex impedance of induction generator for deriving the specific models for each operating mode. Graph theory based matrix equations are easier to modify in order to account for specific effects such as short/long-shunt, core-loss, etc. The resulting equations have excellent symmetry which makes the analysis very easy, fast and accurate. The matrix equations developed by nodal admittance method are solved by fuzzy logic technique to predetermine the steady state performance of single phase SEIG. The experimental and theoretical results are found to be in close agreement.
