Sažetak
Aeolian vibrations of overhead transmission line conductors are usually noticed at frequencies 5-100 Hz. These vibrations can cause the damage and breaking of the conductor due to material fatigue, and can significantly shorten its lifetime.Very large differences among the numerical results obtained by different computational programs are frequently observed. Two main reasons were identified for the large differences among the results. First, the aforementioned programs are based on several different models, i.e. different assumptions that are built into the models. Second, these programs use data from different sources that can differ significantly (wind power, data on the damper's mechanical impedance, mechanical characteristics of the conductor). Overhead transmission line Aeolian vibrations are in practice commonly estimated by using the Energy balance method (EBM) and the Modified energy balance method with using eigenfunctions (MEBM). In order to examine the accuracy of the developed computational programs, based on EBM and MEBM, as well as correctness of the estimation of the data used, results generated using the developed computer programs and data from field measurements using device VIBRECTM 400 are compared in this paper. A very high correlation between the measured field data and the data generated with the developed computer programs (EBM and MEBM) has been obtained.
