| Abstract: | Ice-clad transmission lines can seriously damage a power grid as to cause its partial or whole breakdown. The principles, application status and prospect of some main deicing methods are introduced in this paper. The practical application shows that the methods of DC deicing, AC short-circuit deicing and over-load deicing are feasible and useful, and the DC deicing method has become the most effective means to prevent ice disaster of the power grid. The research and application effects of DC deicing technology in China are reviewed, and the main technology issues in its further popularization and application are presented. |
