Sažetak

There are few methods to archive improved voltage waveform in synchronous hydro generators, while keeping noise and vibrations at satisfactory levels. The number of stator slots, winding arrangement, slot skew and damper bar pitch can all effect the quality of the waveform, but each has both advantages and disadvantages. This method review options, focusing on the slot skewing method.
