在500千伏兰亭变，一场特殊的设备巡视正高效进行——一支"空天地"智能巡检特战队有条不紊地 履行设备主人职责，为秋检期间电网安全运行提供坚实保障。 高空无人机从机巢自主起飞，对避雷针、绝缘子串展开精准扫描；地面机器狗灵活穿梭于设备区， 探查低处隐患；而遍布全站的固定摄像头则全天候"站岗"，实时监测设备运行状态。这场由AI指挥的立 体巡检，已成为守护电网安全的新常态。 这支智巡"特战队"，是国网浙江电力绍兴供电公司打造的"空天地"一体智能巡检系统。如今，它正 从"建起来"走向"用起来"，从"能用"变得"好用"，成为变电站运检人员手中不可或缺的智能利器。 从"建好"到"用好"核心是解决老问题 "以往人工巡检平均每天每站需2人协同，耗时4小时以上才能完成。"一位在运检一线工作多年的老 师傅说道。他提到的不仅是效率问题，更是长期困扰变电站运维的深层痛点：传统人工巡检模式需要运 检人员直接进入设备区作业，尤其在迎峰度夏关键期，运检人员要在高温下近距离检查带电设备，不仅 工作效率低，更存在人员中暑、触电、高坠等安全风险。同时，面对成千上万个巡视点位，人工巡视不 仅耗时耗力，还容易出现漏检、误判等问题。 图为超高压运检人员 ...

Core Viewpoint - The article emphasizes the evolution of Zhejiang Electric Power in response to extreme weather challenges over the past 20 years, highlighting the transition from traditional disaster response to a more proactive, technology-driven approach to ensure grid reliability and resilience [2][4][19]. Group 1: Historical Context and Development - Twenty years ago, the phrase "Electricity is of utmost importance, and the grid is the lifeline" laid the foundation for Zhejiang Electric Power's mission [2]. - The company has consistently prioritized the understanding of electricity's significance and the protection of the grid, which connects households and supports economic activity [2][4]. Group 2: Technological Advancements - Zhejiang Electric Power has shifted from a passive disaster response to an active network strengthening strategy, focusing on building a "typhoon-resistant grid" [5]. - The company has implemented high-level disaster prevention measures, including the construction of the first self-healing island smart microgrid in Zhoushan, which can operate independently during outages [5][6]. - In Lishui, the reliability of power supply reached 99.99% in 2024, with average outage duration reduced by 37 minutes compared to the previous year [6]. Group 3: AI and Predictive Technologies - The company has developed an AI-based typhoon early warning module that improved prediction accuracy by approximately 30 kilometers, leading to a 69.58% power restoration rate within two hours during typhoon events [13][14]. - The establishment of a typhoon monitoring and early warning center has enhanced the ability to monitor weather conditions affecting the grid [15]. Group 4: Infrastructure and Monitoring Enhancements - Zhejiang Electric Power has installed various sensors and monitoring systems in substations to detect flooding and improve overall grid resilience [8]. - The company has created a robust and intelligent distribution network, enhancing the overall power supply capability and reliability [8][16]. Group 5: Future Directions - The company aims to further enhance the grid's resilience and self-healing capabilities through the integration of artificial intelligence and advanced monitoring systems [25][26]. - There is a focus on expanding the coordination of energy sources, loads, and storage to improve system flexibility and reliability in the face of uncertainties [27].
