Galloping Characteristics of 10kV Overhead Transmission Line Using Finite Element Analysis Method

2021 International Conference on Electrical Materials and Power Equipment (ICEMPE), 2021
10kV overhead transmission lines are easy to be affected by severe weather conditions such as strong wind and icing, which is prone to galloping fault. This seriously affects the safety and reliability of distribution network. For the galloping characteristics of 10kV overhead transmission line in severe weather conditions, ANSYS finite element ...

Dynamics of a circular cylinder with an attached splitter plate in laminar flow: A transition from vortex-induced vibration to galloping

, 2020
Flow-induced vibration (FIV) of a circular cylinder with an attached splitter plate in a laminar flow with Re = 100 is studied numerically. First, the mechanical model along with mathematical formulations is proposed to describe the fluid-structure ...

Aerodynamic force characteristics and galloping analysis of iced bundled conductors

Wind and Structures, 2014
Aerodynamic characteristics of crescent and D-shape bundled conductors were measured by high frequency force balance technique in the wind tunnel. The drag and lift coefficients of each sub-conductor and the whole bundled conductors were presented under various attack angles of wind. The galloping possibility of bundled conductors is discussed based on

Analysis of Galloping Tension Characteristics at Suspension Points of Continuous Span Transmission Lines

2020 10th International Conference on Power and Energy Systems (ICPES), 2020
Based on fluid dynamics and finite element theory, FLUENT platform was used to simulate the air flow field around the crescent ice-covered four-split conductor, and its aerodynamic parameters and aerodynamic loads were obtained. The finite element simulation is carried out in ABAQUS software by using the UEL subroutine, and the tension characteristics ...

Detection technology for inertial behavior of three degree of freedom wire galloping

2024 6th International Conference on Energy, Power and Grid (ICEPG)
Due to the influence of various factors such as weather on wire galloping, when designing a three degree of freedom wire galloping inertial behavior detection technology, there is often a problem of low detection accuracy caused by inaccurate analysis of

Evolution of a 3D Gallop in a Quadrupedal Model with Biological Characteristics

Journal of Intelligent & Robotic Systems, 2010
The gallop is the preferred high-speed gait for dynamic locomotion in most cursorial mammals. Due to the lack of good analytical models and proven control strategies, however, the gallop remains an elusive goal in the field of legged robotics. While there have been several attempts at creating a gallop, none have captured all of the important dynamic ...
