| Abstract: | The causation and specific scheme of the improvement made on the connection mode of the stator winding in a super-large hydropower generator are described herein.Based on the in situ practicalities,the modes of the internal short-circuit faults possibly occurred as well as the characteristics of new faults and their laws are analyzed under the comparison made between the changes of the stator winding structures before and after the improvement on the connection.On the basis of this,the effect from the improvement on the action sensitivity of the protection for the original hydropower generating unit is studied as well. |

| Keywords: | internal fault stator winding connection mode generator protection super-large hydropower generator |
