In order to solve the problem of low-voltage distribution network for low-voltage users safe electricity utilization and load regulation control, aiming at the system architecture, topology and technical requirements of low-voltage user safety assurance and load regulation control system, a set of low-voltage distribution network data acquisition and monitoring control (SCADA) system with all low-voltage switches is proposed and constructed. The system can realize the sharing of low-voltage users' electricity information, ensure the safety of customers' electricity consumption, and prevent the abnormal influence of low-voltage distribution network on the stable operation of high-level power grids. The research results have been successfully applied in the area in Xijiang River, which not only improves the intelligence and automation level of local low-voltage distribution network, but also provides a theoretical basis for future distribution network construction planning in other areas.
