智能巡视系统在220kV智慧变电站的建设与应用

Construction and Application of Intelligent Inspection System in 220 kV Smart Substation

变电站是电力系统安全可靠运行中不可或缺的环节,而设备巡视工作是变电站运维管理的主要工作内容之一,巡视效率及质量对电力系统运行水平有着直接的影响。以220 kV慈湖变电站为例,结合现有的智能巡视技术,制定慈湖变电站智能巡视系统的建设方案。针对传统机器人只能采用专网的问题,在直接接入型和边缘节点型2种常见的智能巡视系统类型基础上,提出了慈湖变电站智能巡视系统的架构,概述了该系统的整体建设情况和感知设备,分析了智能巡视类别、巡视策略以及系统功能,阐述了该系统的实际应用效果。慈湖变电站智能巡视系统的建设与应用能实现变电站无人化巡视,强化了设备状态管控力,在一定程度上示范引领了变电站智能巡视发展。

Substations are an indispensable section for safe and reliable operation of power systems,and equipment inspection is one of the main tasks in substation operation and maintenance management.The efficiency and quality of inspections directly impact the operational level of the power system.Taking the 220 kV Cihu Substation as an example,this paper develops a construction plan for its inspection system by combining existing intelligent inspection technologies.Addressing the limitation of traditional robots that can only use dedicated networks,based on two common types of intelligent inspection systems,namely direct access and edge node types,the architecture of the intelligent inspection system is proposed.The paper provides an overview of the overall construction of the system and its perception devices,analyzes the categories of intelligent inspection,inspection strategies,and system functionalities.The practical application results of the system are presented,demonstrating that the construction and application of the intelligent inspection system can achieve unmanned inspections in substations,strengthen equipment state control,and to a certain extent,serve as an exemplary case for intelligent inspection in smart substations.
