Abstract :
The magnitude and waveform of harmonic winding voltage in synchronous generator can be calculated by computing electromagnetic field. But the more important problem is how to optimize the design of a generator, so that the harmonic voltage can meet the need of excitation system well. A design method for 3rd harmonic excitation system based on computation of electromagnetic field is discussed in this paper. The 3rd harmonic field performance can be adjusted easily by using this method, no matter the generator is no-load or on load. This method was proved be of effective and exact by practice.
