Comparison of various methods for reducing transient switching overvoltage of a 500 KV no-load line

Year: 2025

Type: conference-paper

Abstract: Switching overvoltage is closely related to the development of the power grid. In recent years, the rated voltage, line length, and transmission capacity of the power grid have been increasing, and the resulting switching overvoltage has become more serious. By using the simulation software ATP-EMTP to make the simulation model, this paper simulates the overvoltage generated by the opening and closing of the no-load line, including the simulation of the no-load line closing in different periods, adding an arrester and opening and closing resistance to limit the overvoltage. By comparing the simulation images, the limiting effects of different measures on switching overvoltage are compared.
