Research on EPGIS Spatial Information Security for Smart Grid

Abstract

Through EPGIS, the power grid spatial data, accounting data and business process data are integratedly modeled and managed to form an integrated resource management map of electricity resources and spatial information that can support various activities of the grid and serve relevant businesses. However, due to the existing update and maintenance methods, there are some problems such as unsound update mechanism, cumbersome acquisition process, low efficiency, over-reliance on GPS, lack of security and other issues, seriously restricting the quality and safety of power grid resource information updates. In this paper, a general technical framework of power grid spatial information security management is proposed. Security design is carried out from three aspects: data layer, logical layer and presentation layer. EPGIS data processing security protection tool and application security protection tool are also designed. The mechanism achieved multi-dimensional, all-round security for EPGIS.
