| Abstract: | In order to optimumly select the third harmonic winding of harmonic exciting generator, the paper anlayses and calculates the air-gap magnetic field distribution of 12 kW and 50 kW harmonic exciting salient-pole synchronous gererator under no-load and full-load conditions by the finite-element method. The paer analyses the distribution regularity of the third harmonic current and the armature reaction of the third harmonic winding, and calculates the air-gap flux density wave with rotation of the rotor. All calculation results are shown to compare closely with experimental ones. |
