Modeling of 3-phase induction machine as single phase generator for electricity generation from renewable energies in rural areas

Abstract

This paper presents modeling, simulation and experimental results of a three phase induction motor running as single phase generator. Modeling is performed on a small power induction motor with squirrel cage, one phase for excitation and the others for load supply It includes a new model of the total losses, i.e. mechanical, copper and iron losses thanks to the design of experiment method (DoE). Experimental results obtained in Cambodia for load and voltage excitation variations on a reduced power test bench are good agreement with simulations, confirming the validity of the proposed models. Target application is electricity production form pico-hydropower in rural areas in developing countries.
