Configuration of Phase-to-phase Spacer on 1 000 kV Compact Transmission Line
摘要
Abstract
To ensure its safe operation,it is necessary to install the phase-to-phase spacer on compact transmission lines.To study the configuration of phase-to-phase spacer is of great significance.Consequently,by using the calculation software of 3 degrees of freedom（DOF） dynamic model of multi-span line established by Tsinghua University,we obtained the dynamic response of the transmission line under external forces as well as the line tension and static sag both in the presence and absence of phase-to-phase spacer.The results indicate that installing a phase-to-phase spacer with height 14 m and diameter 55 m can effectively suppress the transmission lines＇ non-synchronous movement caused by short circuit electro-dynamic force or strong wind.Moreover,the effects of installing a phase-to-phase spacer on the transmission lines＇ tension and sag are both in an allowable range,and the system can still operate in security.关键词
