Steady state analysis of self-excited six-phase induction generator for alternate renewable energy generation

This paper presents the steady-state analysis of a six-phase self-excited induction generator (SPSEIG) for alternate renewable energy generation under different loading conditions. The analysis is based on nodal admittance method using graph theory as applied to the equivalent circuit model. Unlike with conventional method of analysis, with the proposed method, detailed mathematical derivation for each set of unknown parameter is not required, and the generalized model of SPSEIG dispenses with tedious work of segregating real and imaginary components of complex impedance of induction generator for deriving the specific models for each operating mode. In this proposed method, resultant matrix form is directly solved by Fmincon. Some of the key analytical results are validated by experimental results.
