Galloping Region Division Method of Power Transmisson Lines Based on Galloping Mechanism

摘要

The power transmission lines galloping accidents, can easily lead to major economic losses and serious impact on people's lives. Reasonable division of galloping region for transmission lines, can offer helpful reference and guidance to the design and construction of transmission lines ,so such disasters can be effectively avoided. However, the common method of galloping region division often gives just a rough division, which is difficult to be directly used for guiding engineering practice. This paper proposes a galloping region division method based on galloping mechanism. It takes into account a region's meteorological factors, geographic factors and the type of transmission lines. A series of galloping region division maps can be gotten by this method, to better guide the design and construction of transmission lines.
