Admittance Matrix Model of a Synchronous Machine for Harmonic Analysis

The harmonic analysis of a power system requires appropriate models of all system components. Synchronous machines act as harmonic converters, sensitive to the sequence of the fundamental and harmonic frequencies. This paper describes the derivation of a harmonic model of the machine in the form of a three-phase complex admittance matrix and its application to the harmonic behaviour of an asymmetrically loaded generator.
