Introduction The galloping of transmission lines will lead to trip, worn hardware, broken insulator string, damaged tower-arm and other accidents. In serious cases, collapsed tower accidents may occur. Therefore, it is very meaningful to establish the galloping model of transmission lines and analyze its galloping.
Method Classic and cutting-edge literature at home and abroad was systematically studied, and the research status about bending stiffness, aerodynamic coefficient, numerical simulation, and the analytic method of galloping equations was comprehensively summarized. The advantages and disadvantages of existing research was analyzed, and the development trend of transmission lines galloping topics was summarized here.
Result The relevant results will have high reference value for the development of iced transmission lines galloping in China.
Conclusion At this stage, the research of iced transmission lines galloping has made certain progress and conclusions, but there are still many challenges and problems to be solved.
