| 摘要: |
| 以8台水轮发电机的主保护设计为例，对比了传统设计方案和定量化设计方案的性能．说明不能以每相分支数相或容量相等／相近为理由而相互套用或照搬主保护配置方案。由于100～300MW水轮发电机的绕组设计非常灵活，使得实际可能发生的故障特点各不相同．应作内部学冀兰算决定100～300MW水轮发电机的主保护配置方案。 |

| Abstract: |
| With the main protection designs of eight hydro-generators as examples.the main protection configuration scheme is compared with the quantitative design scheme,which explains that main protection configuration scheme can not be applied indiscriminately to different type hydro-generators with similar branch number or capacity. The different stator winding designs of hydro-generators from 100 to 300 MW lead to different fault features. It is better to design the main protection configuration scheme for medium hydro-generators based on internal fault simulation. |
