摘要：

架空输电线路的弧垂高度是影响电网线路安全运行的关键因素。为合理规划线路路径、模拟弧垂高度,本文基于三维模型技术,运用悬链线公式,使用C语言搭建三维模拟平台,对输电线路进行三维场景模拟。弧垂高度在不同工况下因线路受力不同而变化,该平台支持在全工况场景下对线路进行三维模拟,并根据不同工况下有关安全距离规定,精确计算线路间的距离并进行最短距离校验,极大提高了电网建设和线路规划的科学性,保证输电线路的安全运行。

关键词: 悬链线公式, 输电线路设计, 最短距离, 三维模拟

Abstract:

Sag height of the overhead transmission lines image grid is a key factor in the safe operation of the line. For reasonable line route planning and testing sag height, based on catenary equation and three-dimensional GIS, 3D modeling techniques, using C language, a 3D simulation platform is built for the transmission line to simulate three-dimensional scene. Under different conditions, the stress changes resulting in lines, thereby affecting sag height, so that the platform supports full-line three-dimensional simulation scene conditions, depending on the conditions prescribed safe distance accurately calculate the distance between the lines and the shortest distance calibration, which greatly improves the planning of scientific information for the construction of power grids, precise reference and ensure the safe operation of transmission lines.

Key words: Catenary equation, transmission lines design, shortest distance, three-dimensional simulation
