基于SCADA技术的低压配网控制系统研究

为了解决低压配网用户安全用电及负荷调节控制难的问题,针对低压用户安全保障及负荷调节控制系统的体系架构、拓扑结构、技术需求展开研究,提出并建设了一套低压配网含所有低压开关数据采集与监视控制(SCADA)的系统。该系统可实现低压用户用电信息共享,保障客户用电安全,防止低压配网异常影响高一级别电网的稳定运行。该研究成果在西江某地区得到了成功应用,不仅提升了当地低压配网的智能化、自动化水平,还为其他地区未来配网建设规划提供了一定的理论依据。

Research of low-voltage distribution network control system based on SCADA technology

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.
