Simulation of Phase-to-ground Spacer for Anti-galloping of 500 kV Horizontal Arranged Transmission Lines
摘要
Abstract
Phase-to-ground spacer is a new kind of anti-galloping device.We simulated and researched the anti-galloping of 500 kV horizontal arranged transmission lines.Firstly,we established a finite element model of phase-to-ground spacer and 500 kV horizontal arranged transmission lines,simulated the galloping process of the lines,and analyzed the characteristics of conductor galloping.Then,we comparatively analyzed the line's galloping response before and after installation of the anti-galloping devices according to displacement,trajectory,and tension.The results show that galloping will cause a great damage for transmission line,meanwhile,phase-to-ground spacer can reduce the amplitude of galloping and fluctuation of tension.关键词
