Investigation of skew effect on the behavior and performance of grid connected induction generators

Abstract

This paper proposes the investigation of skew effect on the behavior and performance of three phase, 2.2 kW, 220/380 V, Δ / Y connected, 1420 rpm, 4 poles grid connected induction generators with skewed squirrel cage rotor for supplying electric power to utility grid. Skewed rotor with angle of 0°, 5° and 10° for grid connected induction generators are employed. Analysis and comparative study on operating of induction generators under transient and steady state conditions have been performed. Research results will be guidelines for an application of wind induction generator for electricity generation.
