摘要

近年来，随着特高压长距离架空输电网络的快速扩展及电力基础设施覆盖范围的持续扩大，覆冰灾害发生频率显著攀升，导线断裂、杆塔倒塌等连锁性故障事件频发，对电力系统的安全稳定运行构成严峻挑战。为降低冰灾对系统的冲击，亟需开展冰灾期间电力系统韧性提升方法研究。根据气象预报信息和微地形信息计算输电线覆冰厚度，分别求出线路与杆塔所受的总荷载，根据线路与杆塔各自的设计强度在线评估输电线故障率的变化，模拟系统运行状态，构建韧性指标进行系统韧性评估，并分别采用灾前、灾中和灾后三个阶段的提升方法，提升电力系统的韧性。

Abstract

In recent years

with the rapid expansion of ultra-high voltage （UHV）long-distance overhead transmission networks and the continuous extension of power infrastructure coverage

the frequency of ice disasters has surged significantly.Chain fault events such as conductor breakage and tower collapse have occurred frequently

posing severe challenges to the secure and stable operation of power systems.To mitigate these impacts

it is crucial to enhance power system resilience during ice disasters.This involves calculating ice thickness on transmission lines using weather forecasts and micro-terrain data

determining the total load on lines and towers

and assessing the change in line failure rates based on design strengths.System operating states are simulated to construct resilience indices and evaluate system resilience.Enhancement methods are applied in pre-disaster

during-disaster

and post-disaster stages to improve system resilience.
