Research on a method of intelligent reconstruction of conventional substation

Abstract

With the developing of communication technology and power electronic technology, building smart grid has been a development trend for power grid in the future. Smart substation is the key link of building smart grid, as the point of the construction for the smart grid. Building smart substation mainly through build the new smart substation and transformation of conventional substation intelligent The thesis make a series studies on the scheme of transformation of conventional substation intelligent based on the reliability of substation operation and economy of transformation cost. At first we analysis difference about main technical between smart substation and conventional substation, and make sure the main technical about the transformation of conventional substation intelligent. Then we discuss innovation methods about equipment and function in station layer, process layer and interval layer to build three layers and two networks in smart substation. Finally, we get a scheme of transformation of conventional substation for Integral function of Substation, and this thesis proposes the scheme of transformation intelligent which takes into account the requirements of the development of smart substation technology reliability and economy.
