Abstract

A novel approach to modelling doubly-fed induction machines facing (distorted) ac power networks is presented. It takes place in the frequency-domain and is based on frequency coupling matrices using tensor algebra. Benefits of this comprehensible and fast modelling approach are demonstrated by establishing a feed-forward control signal that reduces stator current harmonics and torque ripple thereby improving the network compatibility and reducing the stress on the mechanical drive train. Dynamic simulations using PSCAD/EMTDC and MATLAB/Simulink are presented demonstrating the effectiveness of the proposed modelling approach and the feed-forward compensation scheme.
