Design of Distribution Automation Master Station System Integration Scheme Based on “n + 1” Architecture

Abstract

More and more network and provincial companies within the State Grid have adopted the “n + 1” architecture, that is, the deployment of production control at the regional and municipal levels, and the centralized deployment of information management at the provincial level to build the distribution automation master station system. The main station system of information management regional can independently evolve into the distribution cloud main station. In response to the construction trend of “n + 1” architecture, an integrated scheme’ of distribution automation master station system based on “n + 1” mode is proposed, and it is verified and analyzed on the new generation of distribution master station system constructed by State Grid Ningxia Electric Power Company. The verification and analysis on the above show that this integrated solution can solve the problems of cross-regional data synchronization and distributed data storage based on the “N+1” mode of the power distribution master station system, while avoiding the repeated construction of the information management area. At the same time, this construction mode can reduce operating costs, improve the efficiency of distribution network data utilization. At present, this scheme has been applied in Sichuan, Inner Mongolia, Jiangsu and Shanghai Electric Power Company, has a strong demonstration.
