A Novel Intelligent Working Monitoring and Guarding System of Smart Substations Based on UWB Positioning and Aerial LiDAR Data

—This paper analyzes the current status of power production safety, introduces the realization principle of intelligent working guarding system in substations, and delves into the technologies of positioning and intelligent video analysis based on ultra wideband (UWB) technology and high resolution digital spatial data of the substations. Based on the acquired data, an intelligent working monitoring and guarding system with various functions, including task management, realtime monitoring, alarm warning, region division, and replaying of historic data, has been developed by utilizing the technologies of 3-Dimension (3D) modeling of the substation by using aerial light detection and raging (LiDAR) and virtual reality (VR) for practical implementation.
