Nonlinear inelastic responses of transmission tower-line system under downburst wind
Engineering Structures, 2016Abstract Electrical transmission tower-line systems transport the needed electrical energy. These systems are spatially distributed and subjected to extreme natural environmental events such as downbursts. The capacity curve of a single tower has been reported under the downbursts but neglecting the turbulent wind component and potential dynamic ...

The Establishment of Transmission Tower Line System and Its Wind Load Simulation
2021 IEEE 5th Information Technology,Networking,Electronic and Automation Control Conference (ITNEC), 2021The transmission tower line system includes towers, wires, ground wires, insulator strings and so on. To study the changes of transmission lines under wind load is of great significance. This article explains how to automatically establish a transmission tower line system and the system simulation under wind loads.

Analysis on Galloping Responses of Transmission Tower-Line System
Applied Mechanics and Materials, 2014Nonlinear finite element model of a transmission tower-line system was set up and galloping of iced bundle conductors in the system was numerically simulated by means of ANSYS software. Based on galloping trajectories, vibration frequency, galloping order, conductor tension; unbalanced tension characteristics of iced conductors, it was shown that ...

Impact of transmission tower-line interaction to the bulk power system during hurricane
Reliability Engineering & System Safety, 2020Abstract A Hurricane is a severe weather event that has caused massive blackouts in the United States. Previous studies about a hurricane's impact on the power system were mainly conducted through statistical analysis. However, there is limited research that reveals the physical law governing power outage and system-level performance. Therefore, this
