| 摘 要： | 从多个水轮发电机主保护定量化设计的工程实践中发现某些绕组形式的发电机难以取得令人满意的保护性能。提出通过合理选择定子绕组形式，兼顾电机设计和继电保护的要求，在绕组设计阶段就力求减少继电保护的动作死区。建议首选保护性能优异的整数槽“全波绕组”，同时针对其他绕组形式，探讨相应的综合优化设计规则，在不改变电机电磁性能的前提下，采取相应措施减少定子绕组内部短路时继电保护动作死区的存在比率。

| Abstract: | 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... |
