| This dissertation explains in detail the structure and tenet of working of the controllable magnetic valve arc-extinguishing reactor and analyses the small current neutral grounding system and the special feature of the single phase grounding happening, based on above all, by a new control method which organically combines line selection based on comparing amplitude and comparing phase and automatic control of the controllable magnetic valve arc-extinguishing coil, we can realize synthetically optimal control of line selection and compensation to capacitive current in singlephase earth fault. |
