一种基于超长弹性细杆模型的大截面导线弧垂计算方法
A method for sag calculation of conductor with large section based on super long thin elastic rod model
摘要
Abstract
With the development of large-scale ultra-high-voltage transmission projects,conductors with large section had been gradually applied to various transmission lines construction,which actually had obvious advantages in both big current carrying capacity and stable dynamics properties.Exactly and reasonably presenting the static configuration and sag of lines became one of the most important questions in designing of lines and anti-vibration works.In this paper,characteristics of bending stiffness of conductors with large section had been carefully considered.The equation with constant torsion curvature of super thin elastic rod model had been used,on this basis,the curvature distribution function of single conductor within the span had been calculated through the harmonic balance method.Combing with numerical integration solution of Frenet-Serret vector equations,the static configuration of conductor was obtained.The advantages and effectiveness of the proposed method were verified by comparing catenary formula with the test results.关键词
