Transmission Line Conductor Galloping Analysis using FEM
To find a mathematical standard of the galloping mechanism, and it is required to compare the existing mathematical standards on the conductor galloping. In this paper, using the Hamilton principle the continuum cable standard for transmission lines was proposed. Discrete standards of one degree of freedom, two degree of freedom, and three degree of freedom were obtained from the Garlekin funct...
متن کاملFinite Element Modelling of Transmission Line Galloping
A computationally efficient, finite element idealization is presented to analyse galloping, which is characterized by large amplitude vibrations of iced, multi-span, electrical transmission lines. A three-node, isoparametric cable element having three translational and a torsional degree-of-freedom at each node is developed to model a conductor. Support insulator strings and remote conductor sp...
متن کاملA Fiber Bragg Grating-Based Dynamic Tension Detection System for Overhead Transmission Line Galloping
Galloping of overhead transmission lines (OHTLs) may induce conductor breakage and tower collapse, and there is no effective method for long distance distribution on-line galloping monitoring. To overcome the drawbacks of the conventional galloping monitoring systems, such as sensitivity to electromagnetic interference, the need for onsite power, and short lifetimes, a novel optical remote pass...
متن کاملMitigation of Magnetic Field under Double-Circuit Overhead Transmission Line
This paper studies the effect of various mitigation loop configurations namely: single horizontal mitigation loop (two conductors), two separate horizontal mitigation loops (four conductors) and single vertical mitigation loop (two conductors), on the magnetic field produced by 220 kV double-circuit overhead transmission line. Also, in this paper a further reduction in the magnetic field is ach...
متن کاملSimulation of Single Conductors Galloping Oscillations and Estimation of their Maximum Amplitudes
Overhead transmission lines are influenced by different factors which are mostly electrical and mechanical. These factors can cause problems for lines, distortions in network and outage of line. In designing transmission lines mechanical properties are evaluated after selecting a suitable conductor and clearance with regard to electrical properties. In lines designing, an important mechanical p...
