DYNAMIC RESPONSES OF UHV TRANSMISSION TOWER-LINE SYSTEM AFTER ICE- SHEDDING IN HEAVY ICE ZONES

摘要：

The finite element models of typical 1000kV transmission tower-line sections in heavy ice zones are created by means of the ABAQUS/CAE software and the dynamic responses of the models with different structure parameters in different ice-shedding conditions are numerically investigated. Based on the linear relations, two simplified formulas for the maximum jump height and horizontal swing amplitude of the transmission lines with odd number of spans after ice-shedding are proposed for the design of the UHV transmission lines.
