Simulation and Experimental Investigation of DC Ice-Melting Process on an Iced Conductor
IEEE Transactions on Power Delivery, 2010Ice melting with dc is one of the key technologies to prevent the Chinese power grid from ice storms. Especially after the severe ice storm in the southern part of China in early 2008, dc ice-melting technology has drawn more attention than ever before.

Impact of icing severity on corona performance of glaze ice-covered conductor
IEEE Transactions on Dielectrics and Electrical Insulation, 2017This paper presents the results of laboratory experiments carried out on an ac-energized stranded conductor subjected to simulated glaze icing, which were conducted in a corona cage located in an artificial climate chamber. With the increase of icing duration, the grow of icing severity of conductors lead to the corona onset voltage fell from 54.8 to ...

The effect of conductor diameter upon the thickness of icing
2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016Due to the recent situation in the neighbouring countries, where icing damaged many transmission and distribution power lines and caused financial losses, it is necessary to operate weather stations. Last icing events caught the overhead power line operators unprepared because they occurred in locations where the design did not expect any icing.

Parameter Study on Galloping of Iced Bundled Conductors
2010 Asia-Pacific Power and Energy Engineering Conference, 2010The aerodynamic coefficients of iced quad-bundled conductor varying with attack angle determined by wind tunnel test are presented. A cable element with torsional degree-of-degree used to simulate the iced conductor is obtained in ABAQUS software by releasing the two bending degrees-of-freedom and setting the material to be incompressible.

Temperature characteristic of DC ice-melting conductor
Cold Regions Science and Technology, 2011China is developing DC ice-melting method for the de-icing of overhead transmission lines after the ice storm in 2008. Melting ice apart, the Joule heat produced by DC heats the conductor. It is significant to investigate the temperature characteristic of the ice-melting conductors in order to protect the conductor from being damaged by overheating ...

Influence of turbulence on the galloping instability of iced conductors
IEEE Transactions on Power Apparatus and Systems, 1975Previously reported wind tunnel dynamic tests on spring-supported models of transmission line conductors with crescent-shaped accumulations of ice, showed that the galloping instability of these models was significantly affected by turbulence in the air flow.

Anti-Icing Mechanism for a Novel Slippery Aluminum Stranded Conductor
ACS Applied Materials & Interfaces, 2023The icing of transmission conductor seriously threatens the safe operation of power grids. Slippery lubricant-infused porous surface (SLIPS) has shown great potential for anti-icing applications. However, aluminum stranded conductors have complex surfaces, and the current SLIPSs are almost prepared and studied on small flat plates.

Nonlinear Numerical Simulation of Iced Conductor Galloping
Applied Mechanics and Materials, 2010A two-node cable element which the axial torsion and geometrical nonlinear were considered was developed based on the update Lagrange formulation, and a model of multi-span transmission line for galloping analysis was established. A nonlinear numerical simulation of single iced conductor galloping was proposed.

Influence of AC electric field on conductor icing
IEEE Transactions on Dielectrics and Electrical Insulation, 2016Atmospheric icing of conductors is a major issue for the safety, design and operation of transmission lines. In the presence of an electric field on the surface of the conductor, ice accretion mechanism behaves differently compared to non-energized state.
