| Abstract: | It is not always feasible to equip an alternative transformer for all 500 kV/400 MVA single-phase auto- transformers in the substations because of the parameter differences. In this paper,parameters selection of the all-ap- plicable alternative transformer were studied by calculating the circulating current in transformer parallel operation and zero-sequence voltage. Such alternative transformer can substitute any transformers of this kind and achieve the requirements of safety and reliability. Presently they have been successfully used in electric power production. |
