Resumen de Effect of magnetic slot wedge on the performance of bulb tubular turbine generator
Hongbo Qiu, Xutian Zou, Xiaobin Fan
Owing to the salient pole structure and stator slots of hydro-generator, the air gap magnetic field in the generator is unevenly distributed. High-frequency harmonic components contained in the inhomogeneous air gap magnetic field will have a negative impact on the generator performance. The purpose of this paper, therefore, is to improve the distribution of air gap magnetic field by using appropriate magnetic slot wedge, thereby improving the generator performance.
