Frequent occurrence of ice disaster is one of the most threats to the power system. The intelligent technologies such as cloud computing, big data, internet of things, mobile internet and artificial intelligence continue to integrate, innovate and develop rapidly, and will affect profoundly the development of anti-icing technology in power system. Firstly, an overview of the connotation of intelligent technologies and their applications in power system is summarized,its application scenes in pre-disaster prevention and early warning, ice monitoring, melting and de-icing technology and disaster relief are discussed. Secondly, the application route scheme of intelligent technologies in anti-icing work is highlighted, and the solution path of related engineering and technical problems with specific intelligent technology is analyzed. Finally, it is verified that the intelligent technologies have a wide range of application scenarios in anti-icing work through analysis, furthermore, the development direction of anti-icing intelligence is pointed out systematically.
