Abstract

Abstract: Transmission line icing is a serious threat to the safe and stable operation of China's power system. To address the problem of subjective classification of ice-covered microtopography areas for transmission lines, a research is carried out on using the digital elevation model (DEM) and the icing-caused fault statistics of transmission lines of Jiangxi Province to identify the saddle microtopography for transmission line corridors. A set of indicators are proposed for identifying the saddle microtopography, and used to extract the microtopography features of the sample areas. On this basis, a method is proposed for identifying the saddle topography for transmission line corridors. The validity of the saddle topography features and the proposed identification method has been verified. The research results can provide a reference for differentiated anti-icing design of transmission lines.

Key words: transmission line, ice-coverd, microtopography, feature extraction, digital elevation model (DEM)
