At the beginning of 2020, a large-scale cold wave has affected the Bohai rim and central China, causing icing and galloping of transmission lines in Beijing, Tianjin, Hebei, Liaoning, Shandong, Hubei and other places, and causing some lines to trip. In this paper, the the temperature and other real-time data of line condition were considered, and a real-time analysis algorithm of galloping characteristics was proposed. In the process of this cold wave, a galloping phenomenon is recorded and analyzed in detail, which provided scientific and technological support for galloping prevention and control.
