Description

technical field [0001] The invention relates to an on-line monitoring system and method for an overhead power transmission line, which is mainly suitable for on-line monitoring and fault diagnosis of breeze vibration, conductor temperature and wind deflection angle of an overhead power transmission line in a power system, and belongs to the technical field of electric power monitoring. Background technique [0002] Overhead power transmission lines, especially ultra-high voltage, long-distance, and large-capacity power transmission lines, often experience wind vibrations exceeding the allowable amplitude due to the influence of meteorological conditions and external environments during operation, which often leads to fatigue of some line components Damage, such as fatigue broken strands of the ground wire, fatigue damage or wear of fittings, spacers and tower components. Among them, the fatigue and broken strands of the ground wire are a common problem in overhead power tran...
