从“示范站”到“标准化”，看变电站智巡的进阶之路

Core Viewpoint - The "Air-Ground" intelligent inspection system developed by State Grid Zhejiang Electric Power Shaoxing Company enhances the efficiency and safety of power grid inspections through the integration of drones, ground robots, and fixed cameras, transforming traditional inspection methods into a more automated and intelligent process [1][3][10]. Group 1: Traditional Inspection Challenges - Traditional manual inspections required two personnel and over four hours per station, leading to inefficiencies and safety risks such as heatstroke and electric shock [2]. - The limitations of single inspection methods resulted in coverage blind spots, with drones, robots, and cameras each having their own weaknesses [2][4]. - Data silos hindered decision-making, as maintenance personnel spent excessive time comparing data from various systems, affecting the timeliness of defect detection [2]. Group 2: Intelligent Inspection System Features - The "1+3" intelligent inspection system integrates three inspection technologies into a single platform, utilizing AI algorithms for data fusion and analysis, achieving comprehensive coverage and improved usability [3][4]. - The system features a three-layer perception network: high-altitude drones for hard-to-reach areas, ground robots for complex environments, and fixed cameras for continuous monitoring [4]. - The system has improved inspection efficiency by approximately 60% and defect identification rates to 95%, making it a valuable tool for maintenance personnel [5]. Group 3: Emergency Response Capabilities - The upgraded intelligent inspection system can autonomously initiate emergency inspections within 30 seconds of an incident, significantly enhancing response times [6][7]. - The system allows for intelligent path planning in complex fault scenarios, improving the precision and flexibility of inspections [7]. - Post-upgrade, the system's preliminary fault identification rate reached 90%, and emergency response times are expected to decrease by nearly 70% [7]. Group 4: Standardization for Broader Implementation - The company is developing a "5S" standardization system to address common challenges in the deployment of intelligent inspection systems, covering hardware, planning, architecture, algorithms, and team building [8][9]. - The standardization aims to create a replicable model for deploying intelligent inspection systems across multiple substations, with plans to implement this in seven additional 500 kV substations by the end of 2025 [9][10]. - The dual approach of technological innovation and standardization is expected to support the intelligent transformation of power grid operations and modern equipment management [10].
