Abstract: Aiming at the suggestion of the dispatch department, in which the reverse power transmission test of the main transformer was not recommended, a new fast switching over system debugging method was designed. By using this method, the dynamic switching over of auxiliary power before the unit starting can be realized; and the correctness of the dynamic switching of the fast switching over system after the unit was put into operation had been increased.
