摘要
传统配电网继电保护方式在复杂工况下存在误判率高、动作延迟大及自适应能力不足的问题,难以满足智能配电网对安全性与实时性的需求。因此,设计一种基于物联网的智能继电保护系统,通过智能终端与同步测量单元实现多源运行数据采集,结合5G与光纤混合通信网络支撑下的边缘-云端协同计算,完成多源信息融合与故障特征识别。实验结果表明,该系统在动作时延、保护精度与健壮性方面均优于传统方案,具有良好的工程适应性与推广价值。
Traditional distribution network relay protection mode has the problems of high misjudgment rate,large action delay and insufficient adaptive ability under complex working conditions,which is difficult to meet the requirements of intelligent distribution network for security and real-time.Therefore,an intelligent relay protection system based on the Internet of Things is designed,which realizes multi-source operation data acquisition through intelligent terminals and synchronous measurement units,and combines edge-cloud collaborative computing supported by 5G and optical fiber hybrid communication networks to complete multi-source information fusion and fault feature identification.The experimental results show that the system is superior to the traditional scheme in action delay,protection accuracy and robustness,and has good engineering adaptability and popularization value.
