Discussion On Design Scheme Of Digital Substation

The automatization of transformer substation achieved a certain level, for example, the new built substation will adopt integrated substation automation system. The widely adoption of substation automation technology improves the dispatching ability of power grid and of transmission distribution.The speed and accurate transmission of information in power systems play a more and moreimportant role in electric power production, especially in power system operation and overhaul. Transformer substation changed from general to integrative automatization. Reeently, some problems are found about transformer substation, which take great effect of the development of electric power. Many scientists make great efforts on the academic research and actualization of digital transformer substation all over the world. However, these theories and implementary methods are not enough comprehensive, systemic and material. Therefore, I analyse the theories of digital transformer substation roundly in artiele. Theoretic analysis also is used of the build of transformer substation practically. In the wake of the development of intelligent electric, especially intelligent switch and the Non Conventional Instrument Transformer, the automatization of transformer substation will be the new stage of digital development.
