ABSTRACT: From the introduction of the power industry to the constitutes of the power system ,the article reveals gradually that the transformer substation plays an important role in the power system and explains systematically the history of the transformer substation which is in the past 、at present and in the future .Combining with the actuality in the power industry , the article emphasizes on the introduction of the transformer substation automation. On the basis of the cognition about the transformer substation, We design a 220KV transformer substation , putting together the actual condition and according to the design theory .The second part of the transformer substation is emphasized on .such as the design and choice .The equipment for the transformer substation is ascertained by the theory .According to the production condition at present , a transformation substation is made up of a set system elected properly.
