220 kV架空线路与双重化保护技术探析

Analysis of 220 kV Overhead Line and Double Protection Technology

220 kV电网线路的架空设计及其双重化保护技术的应用,对整个电网线路输电运行安全性和可靠性有着重要的作用和影响,是电力系统建设与发展中研究和关注的重点。本文将结合220 kV电网线路架空设计中的双重化保护技术标准,围绕220 kV架空线路的双重化保护重合闸配合技术进行研究,以供参考。

The overhead design of 220 kV power grid lines and the application of dual protection technology play an important role and infl uence on the safety and reliability of transmission operation of the whole power grid lines,and are the focus of research and attention in the construction and development of power system.In this paper,combined with the technical standards of double protection in overhead design of 220 kV power grid lines,the coordination technology of double protection reclosing for 220 kV overhead lines is studied for reference.
