Galloping of Transmission Tower-Line System and Anti-galloping Research

摘要：

　　A nonlinear finite element model of transmission tower-line coupling system including transmissions,towers and insulators is established based on ANSYS in this paper.The restarting technology is proposed to solve the vertical,horizontal and torsional galloping of the transmission conductors.Under the condition of different wind velocity,galloping of tower line system is performed to get amplitude of the transmissions and internal forces of the transmission towers.Based on the typical case,the galloping control measures of using interphase spacers and multi-point weighting are performed.Various layouts projects of the galloping control measures are carried out and the effective ones are attained.
