| 摘 要： | 针对水轮发电机组在停机过程中，目前广泛采用的机械制动和常规的电气制动中所存在的问题，提出了采用减磁法来进行水轮机发电机组的电气制动。该方法能使发电机的剩磁在合闸时电流大大降低，从而降低了对制动开关的要求，使得采用隔离开关也能满足制动要求。

| Abstract: | For solving the existing problems of machine braking and electrical braking during the process of stoppage of a turbogenerator set, a magnetic reducing method is tecommended, which can greatly reduce the current of generators at switch due to remainder magnetic and abate the demand for braking switch. So the isolator can satisfy the demand of braking of a turbogenerator set. |

| Keywords: | turbo-generator electrical braking magnetic reducing method |
