| Abstract: | On the basis of investigation in the scene of the faults, data analysis, calculation and study, the causes of the stator single phase short circuit faults of generating unit 2 of power plant in Shajiao C,Guangzhou, were analyzed.Considering such an example, a calculating method with more preciseness of the short circuit current was introduced. A suggestion on the fixed structure design of the end of stator windings and setting up a vibration monitoring system of the end of stator windings was brought, which can be referred in large capacity generating units made in our country. |
