Study on aeolian vibration suppression schemes for large crossing span of ultra-high-voltage eight-bundle conductors

Ultra-high-voltage transmission line is prone to severely aeolian vibration, especially for the large crossing span. However, few studies were conducted previously, as a result of high nonlinearity and complexity of the bundled conductor aeolian vibration system. This article introduces the analytic...

However, few studies were conducted previously, as a result of high nonlinearity and complexity of the bundled conductor aeolian vibration system. This article introduces the analytical models of conductor and damping devices first, to get the key factors for aeolian vibration and to direct the experimental study based on the energy balance principal. Second, the self-damping characteristics of single sub-conductor and energy dissipation power of vibration damper are tested in the laboratory. Third, two aeolian vibration schemes, the first one with vibration dampers only and the second one with both vibration dampers and damping wires, are proposed and evaluated experimentally on the single sub-conductor and then on the eight-bundle test spans. It is found that the concerned conductor has excellent damping effect at high-frequency range and that both of the two schemes show satisfactory aeolian vibration suppression result, but the second one is recommended for its good long-term service performance. This study provides useful reference for aeolian vibration suppression of ultra-high-voltage lines, to avoid fatigue failures of components induced by aeolian vibration and to improve the mechanical security of transmission lines.

abstract	Ultra-high-voltage transmission line is prone to severely aeolian vibration, especially for the large crossing span. However, few studies were conducted previously, as a result of high nonlinearity and complexity of the bundled conductor aeolian vibration system. This article introduces the analytical models of conductor and damping devices first, to get the key factors for aeolian vibration and to direct the experimental study based on the energy balance principal. Second, the self-damping characteristics of single sub-conductor and energy dissipation power of vibration damper are tested in the laboratory. Third, two aeolian vibration schemes, the first one with vibration dampers only and the second one with both vibration dampers and damping wires, are proposed and evaluated experimentally on the single sub-conductor and then on the eight-bundle test spans. It is found that the concerned conductor has excellent damping effect at high-frequency range and that both of the two schemes show satisfactory aeolian vibration suppression result, but the second one is recommended for its good long-term service performance. This study provides useful reference for aeolian vibration suppression of ultra-high-voltage lines, to avoid fatigue failures of components induced by aeolian vibration and to improve the mechanical security of transmission lines.
