Modelling of Aeolian vibration of single conductors strung at relatively high tensile load - Application to HV & UHV lines

Research conducted by Working Group B2.31 (formerly TF 1 of WG B2.11) and summarised in reports [1] & [2], covers the modelling of Aeolian vibration of an undamped single conductor and of a single conductor plus one damper. These reports define the expected vibration level and assess the uncertainties associated with the present technology based on the Energy Balance Principle (EBP) and a shaker-based approach. It has been shown that analytical methods based on the EBP and a shaker-based technology can provide a useful design tool for damping systems that protect a single conductor against Aeolian vibration.
The purpose of the present report is to evaluate the effectiveness of thesemethods for the design and/or verification of the damping system of long, single conductor spans strung at…
