| 摘要: |
| 不同型号的发电机，它们的三相绕组有不同的空间布置，发生内部矩路的位置和种类各不相同，相应的主保护配置方案也迥然不同，因此不同型号的发电机有各自的主保护配置方案，不能搬用或套用额定容量相等，额定电压相同（但型号不同）的发电机的主保护配置方案，在掌握了定子绕组内部短路电流的正确计算方法之后，现有的发电机主保护设计 既有必要也有可能逐步完善，提高，以平班发电厂发电机主保护设计为例进行了说明。 |

| Abstract: |
| The space distribution difference of three-phase winding leads to the variation of inter-nal stator winding faults in location and type,so that different types of generator need to select different disposition of main protection to fit them.The improper copy method that different types of generators with the same rated capacity and voltage use the same disposition of main protection could be improved step by step after the proper short-circuit current calculation of stator winding is fulfilled.The proposed design method is explained with the main protection scheme design for Pingban generator. |
