Calculation method for dynamic stiffness of multi-span overhead transmission lines

HIGHLIGHTS

  • who: LV ZHONGBIN and collaborators from the State Grid Henan Electric Power Research Institute, Zhengzhou, China State Key Laboratory of Mountain Bridge and Tunnel Engineering, Jiaotong University, China have published the article: Calculation Method for dynamic Stiffness of multi-span overhead transmission lines, in the Journal: (JOURNAL)
  • how: The results showed that the boundary conditions of a single span can significantly influence the galloping amplitude.

SUMMARY

    Galloping of multi-span conductors can reach high amplitude causing high tension on conductors, and the periodic change of the tension can be leaded to . . .
