Abstract: According to the structure and the character of the magnetic field distribution, the third harmonic potential formula was deduced, the requirement of the self-excitation and the constant voltage was provided. The influence of the armature reaction to the HESG dynamic characteristics was analysed detailedly. On the basis of the analysis, according to the actual parameters of the HESG, the simulation model was established. Through the simulation contrast analysis, the dynamic superiority of the HESG was proved. It is significant for the further research on the HESG. Key words: harmonic excitation; self-excitation; constant voltage; harmonic potential; the third harmonic; characteristic simulation.
