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 ...

Dynamic characteristics and stability criterion of rotary galloping gait with an articulated passive spine joint

Advanced Robotics, 2016
AbstractBased on the simplified planar quadruped model with a passive spine joint, this paper focuses on studying the effect of the spine joint on the dynamic performance and the stability of the rotary galloping gait. The stable, periodic, and symmetric rotary galloping gait is achieved by the particle swarm optimization method without any parameter ...

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 ...

Distribution characteristics of transmission line galloping events and the analysis of key meteorological factors

2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019
Transmission line galloping is one of the most important disasters of power grid in winter. Based on the galloping observations and loss records obtained from the State Grid Corporation of China (SGCC), the distribution characteristics and the key meteorological factors of galloping events are analyzed. The results show that the galloping events appear
