Abstract: Introduction was made to design and realization of Fanchang substation transformation project of the first 500kV substation intelligent transformation project in East China power grid. Analysis was made to the duplex protocol control system, bay level logic blocking, distribution intelligent warning, and distribution status estimation etc key technologies and innovative points. After intelligent transformation, the substation has realized high efficiency operation and maintenance of equipment control, fault alarm and synthetic analysis on the integrated information platform, which reduces costs of operation and maintenance, optimizes resources disposition and raises operation indexes.
Key words: substation; intelligentized transformation; key technology
