ABSTRACT Taking a large‐scale 34‐MW integer‐slot tubular hydrogenerator as a case study, this paper establishes and solves static and transient field models to investigate the effects of two key geometric features – skewed stator slots and shifted magnetic poles – on synchronous reactance, damper bar losses, and no‐load voltage waveforms. The computational accuracy of the model is validated using measured data. The results provide direct guidance for improving the design and manufacturing quality of tubular hydrogenerators.
