Voltage waveform analysis for synchronous generator with rectifier load

Demin Wang

Open publisher page 0 citations

Abstract

When generators work with rectifier load through a transformer ,the output electric quality of generator is very important. Traditional analytic solution is difficult to consider the influence of the damper circuit ,tooth-slot effect ,winding distribution on waveform, so the finite element method coupled circuit in time domain is employed in this paper to analyze voltage and current waveforms, and calculate line-voltage THD of straight generator. This method has very important significance to predict generator-rectifier system performance accurately and configure filter device properly.
