摘要

基于一种计算导线间电磁力的数值方法，利用ABAQUS软件的用户自定义子程序UEL，编写计算子导线间电磁力的单元，实现考虑电磁力的双分裂导线舞动数值模拟方法。利用算例验证了方法和程序的正确性，进而对不同档距覆冰双分裂导线在不同电流强度下的舞动过程进行数值模拟，分析电磁力对线路舞动特征的影响。结果表明，档距较小时电磁力对线路舞动影响很小；档距较大时，电磁力对舞动的影响明显，甚至可能造成两子导线的碰撞。因而，在研究较大档距线路舞动时，有必要考虑电磁力的影响。

Abstract

Based on a numerical method calculating electromagnetic force between conductors, a finite element to determine the electromagnetic force during galloping simulation of twin bundle conductor lines is incorporated into ABAQUS software by means of the user-defined subroutine. The numerical method, which is verified with a numerical example, is employed to simulate galloping of twin bundle conductor lines with different span lengths and analyze the effect of electromagnetic force on their galloping characteristics. It is reflected by the numerical results that the effect of electromagnetic force on galloping of shorter span line is very small, however, the effect on that of longer span line increases with the electric current intensity. Therefore, it is necessary to take into account the effect of electromagnetic force while investigating galloping of bundle conductor transmission lines with longer span.
