中文摘要	Engineering experience of quantitative design of main protection configuration scheme for many hydraulic generators shows that the protection performance for generator with some types of stator winding is unsatisfactory, which is harmful to the safe operation of large generators. New suggestions on stator winding design of large hydraulic generator are presented. That is to select proper type of stator winding to meet requirements of electric machine design and relaying protection as well. In the primary design process of stator winding, dead zone of relay protection act should be ensured as small as possible. It is suggested that integer slots for per pole and per phase "full wave winding" with good protection performance should be selected. For other type of stator winding, combined optimal design principle should be explored. Measures for reducing dead zone ratio of relay protection act caused by inner short circuit of stator winding should be adopted without deterioration of electromagnetic performance of the hydraulic generator.
