The galloping condition of an iced eight-bundle conductor tower line system, under different parameters, is studied by using a finite element model multi-span system. frequency, amplitude, traces conductors wind velocities, span lengths, and initial angles attack are discussed. connection methods compared, based on existing research the relationship between aerodynamic characteristics conditions. results show that situation system varies greatly depending conditions, which has significant...
In order to investigate the oscillate modes of overhead iced transmission lines, this paper employs different approaches obtain galloping responses lines. Firstly, a forcing term is introduced in equation Subsequently, two discrete methods (discrete method Ⅰ (DMⅠ) and Ⅱ (DMⅡ)) are employed transfer partial differential into ordinary equation. The DMⅠ, which transform directly. DMⅡ involves averaging dynamic tensions over span length before subsequent transformation. Then, finite element...
In studying the vibration characteristics of stay cables, response amplitudes and frequencies are traditionally derived using MATLAB programming, a time-intensive process. This paper proposes novel approach by integrating Proper Orthogonal Decomposition (POD) with four machine learning models—Support Vector Machines (SVM), Back Propagation Neural Network (BPNN), Convolutional (CNN), Long Short-Term Memory (LSTM)—to form hybrid models for rapid prediction these parameters. Initially, is...
The new energy-saving conductors have been developed, which can significantly reduce transmission loss. Through icing test and wind tunnel test, the aerodynamic characteristics are experimentally studied. Firstly, actual conditions of single quad-bundle conventional conductor under different atmospheric environmental parameters (such as: velocity, time, temperature) Then, considering that rotation load in environment, influence velocity on growth is studied, drag coefficient compared with...
