Harmonic characteristics of an induction machine connected to a distribution network

This paper presents a complete study of the induction machine allowing the determination of its harmonic characteristics generated in the line current. The method used to analyse the induction machine behaviour is based on the circuit-oriented approach. The developed model facilitates the estimation of frequencies and maximum values of the stator current harmonic components. Using the EMTP/ATP electrical network simulation package, the obtained circuit-oriented model is simulated in normal conditions at the rated load and the results are compared with theoretical results and experimental measurements.
