Abstract:Icing seriously threatens the safe and stable operation of transmission lines. The research on icing prediction and obtaining environment parameters is the basis of anti-icing work of transmission lines. The multi-rotating conductor method is usually used to measure the icing environment parameters, but there is no perfect theoretical basis for the selection of conductor diameter. According to the basic principle of multi-rotating conductor method, an icing model of rotating conductors was established in this paper. The processes of water droplet collision and freezing on rotating conductors were simulated. The icing law of rotating conductors with different diameters and under different environmental conditions was analyzed, and the effects of various environmental parameters on the icing rate of rotating conductors were quantified. A reliable method for selecting the conductor diameter was proposed. Based on the simulation results, the method indicates that the differences of icing rate of conductors with different diameters changes with the change of environmental conditions, the selection of conductor diameter should be set to maximize the difference of icing rate between conductors with different diameters, and make conductor icing rate change sensitively with the change of environment parameters.
