| 摘 要： | 溪洛渡和向家坝水电站共安装了26台770～800MW的巨型水轮发电机组(包括5种不同机型,绕组形式和分支数均有所不同)。经发电机主保护定量化及优化设计过程,发现5种发电机虽中性点侧引出方式、保护方案的配置及保护性能相差悬殊,但其主保护设计过程实质上都是将一台偶数或奇数多分支的水轮发电机简化为一台每相2分支或3分支的发电机,分支的合理分组取决于发电机的故障特点和每相分支数;发电机主保护配置方案的性能则决定于所选择的定子绕组形式,应在绕组选型时兼顾发电机设计和继电保护的要求。

| Abstract: | Twenty-six large-sized hydraulic generators of five different stator winding types with the rating between 770 MW and 800 MW are equipped in Xiluodu and Xiangjiaba power stations.It is found that,though the neutral point leading mode,main protection configuration scheme and protection performance of these generators are quite different,the quantitative and optimal design of generator main protection simplifies the hydraulic generator with even or odd branches into that with two or three branches per phase a... |
