| Abstract: | This paper aim s at som e problems existing in the setting of generation- transform er unit protection,such as stator over load protection of generator,stator turn- to- turn protection of generator,over- excitation protection of main transformer, loss- of- field protection of generator and low im pedance protection located in HV terminal of main transform er etc.Som e shortages of actual protection setting rules are pointed out.Then some advice for solving the problem s are put forward to obtain better effects of protection setting. |
