description | Abstract For the pole shoe and damper winding centre line shifted structure that has been gradually applied in hydro‐generator in recent years, this letter selects one real integer and one fractional slot large tubular hydro‐generator as examples. Then revealed the influence trends of different shift degrees on the no‐load voltage waveform quality and the damper winding loss and heat under rated load conditions. Also, it compared these trends with those of the traditional stator skew 1 slot structure. The results show that for integer slot generator, this kind of shift structure can obtain high‐quality no‐load voltage waveform close to the traditional stator skewed 1 slot scheme, and the damper winding loss and heat is significantly smaller than the latter. For fractional slot generators, this kind of shift structure will lead to the deterioration of the no‐load voltage waveform. |
