摘要
输电线路的稳定是保障电力系统可靠运行的关键支撑。然而,在复杂严峻的气候环境下,输电线路所面临的安全运行风险急剧攀升。其中,冬季线路覆冰及随之产生的脱冰跳跃,是威胁输电线路安全稳定运行的重大风险因素之一。鉴于此,深入剖析输电线路在脱冰过程中的动力响应机制,并积极探索行之有效的策略以减轻脱冰所带来的潜在危害,不仅在理论层面具有深远意义,更对于实际工程应用有着不可忽视的重大价值。对国内外关于输电线路脱冰跳跃现象的研究成果展开了系统的梳理。依据研究目的的差异,将这些研究划分为三大类别:优化研究方法、分析动力响应规律、构建预测模型与简化公式。此外,还对不同脱冰跳跃抑制措施的应用范围和实际效果进行了归纳总结,并在此基础上指明了输电线路脱冰跳跃及其抑制措施研究未来的研究方向。
The stability of transmission lines is a critical factor in ensuring the reliable operation of power systems.However,in complex and severe climatic conditions,the safety risks faced by transmission lines during operation have risen sharply.Among these,ice accumulation on lines during the winter season and the subsequent ice shedding jumps are one of the major risks threatening the safe and stable operation of transmission lines.Given this,conducting an in-depth analysis of the dynamic response mechanisms of transmission lines during ice shedding processes and actively exploring effective strategies to mitigate the potential hazards caused by ice shedding not only holds profound theoretical significance but also have significant practical value for engineering applications.This paper systematically reviews the research findings on ice-shedding jumps in transmission lines both domestically and internationally.Based on the differences in research objectives,these studies were divided into three major categories:optimization of research methods,analysis of dynamic response patterns,and the development of predictive models and simplified formulas.Additionally,the application scope and actual effects of various ice-shedding jump suppression measures were summarized.Based on this,the future research directions of transmission lines ice-shedding jump and its suppression measures were identified.
