Abstract

The no-load electromagnetic field of the synchronous generator by the third harmonic excitation is calculated to grasp exactly the match of the third harmonic windings voltage with excitation system, and the third harmonic windings no-load voltage is calculated using tooth flux method, the validation of this method are verified by the comparison of the calculation results and the experiment results on a third harmonic excitation synchronous generator. Based on the method, some main factors that affect the third harmonic no-load electromagnetic field of the synchronous generators by the third harmonic excitation is analyzed, and some useful conclusions, which guide the design for the third harmonic excitation synchronous generators, are gained.
