摘要
泛在电力物联网是促进电网企业转型升级的重要内容,对保障电网安全可靠运行、实现电力设备精细化管理具有重要意义。变电站作为连接电网输配环节的中间桥梁,依靠泛在电力物联网技术将全面提升状态感知和精准决策能力。基于此,文中结合变电站运行特点和监测需求,阐述了变电站泛在电力物联网的概念、体系架构和主要特征;然后,进一步分析了边缘计算、数据预处理技术、人工智能技术、异构信息融合技术等变电站物联网建设的关键技术;最后,对变电站泛在电力物联网建设面临的挑战及未来的研究方向进行了展望。
The ubiquitous power internet of things(IoT) is important for the transformation and upgrading of power enterprises.It is of great significance for ensuring the power grid to operate safely and reliably,as well as implementing delicacy management for power equipment.In addition,for the substation which is as a key intermediate between transmission and distribution,the application of ubiquitous power IoT technology will improve the capacities of state perception and accurate decision.According to the operation characteristics and monitoring requirements of substation,the conception,architecture and key features of ubiquitous power IoT are elaborated in this paper.Then,the key technologies of substation IoT are discussed,which include edge computing,data preprocessing,artificial intelligence(AI) and information fusion techniques.Finally,the confronting problem and research direction of substation IoT are prospected.
