III. HARMONIC EQUIVALENT CIRCUIT OF SYNCHRONOUS
MACHINE IN D-Q-0 AXIS
For the transient analysis of synchronous machine working on
harmonic condition, the further research of the effects, on power
system harmonic compensation, produced by harmonic currents
in the field circuit of synchronous machine is made from the
angle of circuit analysis. Considering the effects on harmonic
compensation generated by damper windings of synchronous
machine, the branch of damper windings is added to the
harmonic equivalent circuit when the mathematic model is
proposed by using Park transformation. To coincide with
engineering criterion, equivalent inductances are demarcated by
using leakage Inductances and field inductances [10]. The
equivalent circuit is shown in Fig.3.
