Abstract :
A stand alone system consisting of induction generators connected in parallel, has been considered in this paper. Detailed investigation of such system is carried out to find the influence of machine parameters on system performance. The inverse-Γ model of the per-phase steady state equivalent circuit has been used for the analysis. The nonlinearity imposed by the magnetization characteristics of the machines, calls for iterative technique for the solutions of equations derived from the inverse-Γ model. From the investigation it has been found that rotor resistance being the most sensitive parameter, needs careful selection/design. Influences of other parameter variations have also been presented
