| Abstract: | This paper aimed to introduce the special technology features for imported hydrogenerator of Ge He Yan Power Station, especial the technology of stator skew slot, which can be fundamentally cutting the teeth shape harmonic wave and to improve electricity quality. Its practical application is one and only in the domestic field of hydropower. The technology of even airgap can Improve the utilization of airgap flux density and reduce leakage flux from pole shoe; The theory of ＂N -S pole symmetric windings＂ has not been reported in domestic, which is more worth for further study. Hydropower is a green energy. Above new technology is very valuable on promoting and using in the field of hydropwer. |
