Analysis of the Impact of Meteorological Conditions on Huzhou Power Transmission Operation and Maintenance

摘要: 输电线路的安全稳定运行与所处气象条件密切相关，本文以长三角电力枢纽的湖州为研究对象，结合其亚热带季风气候、“西电东送”特高压通道战略定位及总长6356千米输电线路现状，系统分析暴雨、大风、雷电、高温及低温雨雪冰冻五类关键气象要素对输电运维的影响机制，结合近十年数据与灾害案例分析其致灾特征，指出湖州电力运维气象服务存在精细化气象监测不足、数据共享机制缺失、专业服务技术滞后三大短板，并提出构建精细化气象监测网络、提升电力专项预警精准度、深化气象–电力数据协同、强化复合型人才支撑四大对策，为提升湖州电网抗灾与区域电力保障水平提供科学依据。

Abstract: The safe and stable operation of power transmission lines is closely related to the meteorological conditions of their location. Taking Huzhou, a power hub in the Yangtze River Delta, as the research object, this paper systematically analyzes the impact mechanisms of five key meteorological factors—heavy rain, strong winds, thunder and lightning, high temperatures, and low-temperature rain, snow, and freezing—on power transmission operation and maintenance. The analysis is conducted in combination with Huzhou’s subtropical monsoon climate, its strategic position as an ultra-high voltage (UHV) corridor for the “West-to-East Power Transmission” project, and the current status of its 6,356-kilometer-long power transmission lines. By integrating data from the past decade and disaster cases, the disaster-causing characteristics of these meteorological factors are examined. The paper points out three major shortcomings in meteorological services for Huzhou’s power operation and maintenance: insufficient refined meteorological monitoring, a lack of data sharing mechanisms, and lagging professional service technologies. Corresponding countermeasures are proposed, including constructing a refined meteorological monitoring network, improving the accuracy of power-specific early warnings, deepening meteorological-power data collaboration, and strengthening the support of interdisciplinary talents. This study provides a scientific basis for enhancing the disaster resistance capacity of Huzhou’s power grid and improving regional power security.
