Abstract

China is characterized by vast territory and wider distribution of strong wind easy-happening areas (typhoon, tornado and squall line wind). Meteorological environment conditions are complex and harsh in power transmission line corridor passage (especially in alpine regions). Safe operation of power transmission lines is threatened severely by strong wind natural disaster. Traditional technology can't meet the requirement of power grid rapid development on anti-disaster ability. Large-area tower collapse, cable breakage and other catastrophic wind disaster caused by strong wind in alpine regions as well as control techniques thereof are not studied deeply. The applicability of power transmission line on-line monitoring devices in alpine regions still should be further evaluated. In the paper, long-span guide wire aeolian vibration safety in alpine regions and evaluation methods thereof as well as the wind-induced fatigue early-warning model of long-span guide wires were studied. Long-span guide wire aeolian vibration evaluation standard in alpine regions and fatigue damage early-warning model based on rotatory motion effect index were proposed. The blank in the research field of alpine region long-span guide wire aeolian vibration was remedied. In addition, the guide wire wind resistance safety monitoring project of long-span lines in alpine regions was applied. Continuous valid data for more than one year were obtained, thereby providing basis for formulating guide wire aeolian vibration vibration control measures.
