Abstract	A three-phase synchronous machine model is developed for unbalanced harmonic load flow analysis and for initializing EMTP (electromagnetic transient program) transient simulations. Two nonlinear effects, the frequency conversion and saturation, are represented in conjunction with the machine load flow constraints. The model is in the form of a frequency-dependent three-phase equivalent circuit. It can therefore be easily incorporated into existing harmonic programs for systemwide harmonic analysis. Thus, the generation of harmonies by synchronous machines under various load flow conditions and the harmonic interaction between machines and other harmonic sources can readily be analyzed
