摘要

弧垂是输电线路运行维护的重要参数之一,它的大小直接影响到线路的安全稳定运行。输电线路弧垂状态监测装置难以通过实验室检测得到直接验证结果,需要开展现场观测、试验比对。针对传统的计算方法存在效率低的缺点,采用了基于LabVIEW平台的输电线路最大弧垂测量方法。通过对弧垂的计算及过程分析,应用LabVIEW的G语言编制了弧垂的计算程序。依据该程序,录入所需的基本参数即可迅速而准确地计算弧垂值,结果表明该方法可以保证弧垂测量数据的准确性和快速性,有效地克服人为误差,简化实验工作。该方法可应用在输电线路弧垂装置现场检测中。

Abstract

Sag is one of the important parameters for the operation and maintenance of power transmission lines, which directly affects the safe and stable operation of transmission lines. Because the sag monitoring device of transmission line could not obtain the direct verification results through laboratory tests, the site observation and comparison tests should be carried out. Due to the low efficiency of traditional calculation method, a measurement method based on LabVIEW was presented for maximum sag of traditional line. Through the calculation and process analysis of sag, the calculation program of the sag was compiled by using G language of LabVIEW, in which the value of sag could be calculated quickly and accurately by inputting the required basic parameters. The results have shown that this method can ensure the accuracy and rapidity of the measured data of the sag, effectively overcome the artificial error, as well as simplify the test work. It can be applied in the field tests of the transmission line sag.
