Intelligent Operation and Maintenance System of Power Distribution Network Based on the “1+4” Architecture

Digital transformation has become a trend in the field of power distribution network. As the construction unit of the digital production demonstration task, Haizhu Power Supply Bureau is committed to realizing the implementation of the intelligent operation and maintenance (O&M) system and comprehensively improving the personnel labor productivity. This paper presents the intelligent O&M system of Haizhu Power Supply Bureau based on the “1+4” architecture in the smart power distribution network. “1” stands for the power distribution network automation, “4” stands for the smart power distribution room, power pipe gallery, power distribution area (per transformer) and individual mobile operation terminal. For the proposed “1+4” architecture, the configuration principles and technical routes of each part are elaborated. In addition, the proposed intelligent O&M system is verified through typical scenarios such as large-scale emergency events, situational awareness, and intelligent inspection of power grid equipment.
