Impact of pole pair number on the efficiency of an induction generator for a mini hydro power plant
Miralem Hadžiselimović, Matej Mlakar, Bojan Štumberger, 2013, izvirni znanstveni članek

Opis: The aim of this paper is to analyse the impact of pole pair number on the efficiency of an induction generator designed for a mini hydro power plant. Six induction generators with different number of poles were designed: 2, 3, 6, 10 and 14. The basic point of this study is Kaplan turbine, which considering its rotational speed can be directly connected to a 14-pole induction generator. All other induction generators need a speed reducer for appropriate operation with Kaplan turbine, but speed reduction decreases the efficiency of mechanical energy conversion into electrical energy. Consequently this paper presents the efficiencies of induction generators and the summary efficiencies of an induction generator and a speed reducer. At the design phase of the aforementioned induction generators the realization possibility of the prototypes was taken into account, including the mass of active components and used materials.
