“…Power grid infrastructures in many countries around the world are consequently impacted by ice and snow accretions. Some countries in the arctic region, such as Canada, the United States, Russia, Iceland, and Scandinavian countries, have been exposed to these problems since the deployment of electricity networks [1][2][3]. Additionally, power lines crossing mountainous areas are prone to ice and snow, for example, in China or Italy [4,5].…”

“…Therefore, a variety of countermeasures against atmospheric icing of power lines were proposed in the past to avoid or at least to minimize power outages during such ice or snow events. Pohlman et al [1] in 1982 firstly reviewed the various anti-icing and de-icing methods known at that moment. Since then, various other reviews and technical reports have been published [2,[6][7][8][9][10][11].…”

The reliability and efficiency of power grids directly contribute to the economic well-being and quality of life of citizens in any country. This reliability depends, among other things, on the power lines that are exposed to different kinds of factors such as lightning, pollution, ice storm, wind, etc. In particular, ice and snow are serious threats in various areas of the world. Under certain conditions, outdoor equipment and hardware may experience various problems: cracking, fatigue, wear, flashover, etc. In actual fact, a variety of countermeasures has been proposed over the past decades and a certain number have been applied by utilities in various countries. This contribution presents the status and current trends of different techniques against atmospheric icing of power lines. A snapshot look at some significant development on this topic over the last four decades is addressed. Engineering problems in utilizing these techniques, their applications, and perspectives are also foreseen. The latest up-to-date review papers on the applications and challenges in terms of PhD thesis, journal articles, conference proceedings, technical reports, and web materials are reported.

“…At present, the methods of anti-icing and de-icing, such as super-hydrophobic coatings, short circuit method to melt ice [18], and mechanical de-icing, are costly, inefficient, and difficult to maintain. Various ice theories of transmission lines are proposed but lack of scientific design theory and effective anti-icing method of transmission lines [19] maybe restrict the development and popularization of EHV/UHV transmission.…”

Icing degree in the severe icing regions for years is an important factor considered in the anti-icing design of transmission lines. However, there is currently no normalized characterization method for the icing degree of transmission lines, which can be used to record the severity of icing at icing areas over the years and guide the design of transmission lines. This study analyzes collision efficiency of water droplets with various diameters of conductors and investigates the ice accretion law of transmission lines with various diameters under four natural ice types. Therefore, the normalized method of standard ice thickness instead of various ice morphologies is creatively used to characterize icing degree of transmission lines and a lot of field tests which have been done at six natural ice observation stations have verified the effective of the method. The results have shown that: The diameters of conductor and the droplet significantly affect collision efficiency; the relation of standard ice thickness with diameter of conductors for four typical ice types complied with the law of power function. The results can provide important references for the design and external insulation selection of transmission lines in ice region.

De-icing schemes and operations for overhead power line in 10kV, 66kV and 220kV networks based on shunt capacitor over-compensation method are proposed in this paper. This novel de-icing method is based on characteristics of sinusoidal AC and theory of shunt capacitor over-compensation. By utilizing 10kV capacitor bank, which is installed as standard apparatus in substation, reactive current can be transmitted to the specific deicing power line, which leads to over-compensation of network, and temperature of the power line will be increased. This de-icing scheme and operations are proved and verified in 10kV network by on-site experiments. Focus on characteristics and structure of power grid in China, this method is feasible to transferred and applied in 35kV, 66kV and 220kV networks.
