Implementation, modelling and performance analysis of a dual stator‐winding induction generator

Abstract

Purpose

The purpose of this paper is to develop and test a prototype of the dual stator‐winding induction generator (DWIG) and its dynamic model to verify the validity of this machine design as variable speed generator for renewable energy systems.

Design/methodology/approach

Implementation and laboratory test of a DWIG prototype. Analysis and simulation of the developed DWIG model.

Findings

The proposed DWIG makes a better use of energy than a squirrel cage induction generator (SCIG) in variable speed applications. The performance of DWIG with a bidirectional converter is very similar to those described in other studies with brushless doubly‐fed induction generators.

Research limitations/implications

The results can be used to test different control techniques and to analyse the dynamic performance of DWIG‐converter system in variable load and speed conditions.

Originality/value

The stator winding design does not involve a significant increase in the complexity of the machine assembly and cost of this induction machine.
