架空输电线路设计风速的确定及实时监测

Wind Speed Determination in the Design of Overhead Lineand Real-Time Monitoring of the Wind

架空输电线路工程设计中，要进行导线、杆塔风荷载计算，首先要确定设计风速的大小。本文对这方面的问题进行了分析研究，提出了使用风向风速监测记录仪进行风速原始数据的实时监测记录；介绍了该装置的设计原理与实时、准确测量输电线路走廊风向风速原始数据的方法；并设计研制了自动监测记录仪，用微机技术实现，试运行效果良好。

To calculate the wire and tower wind load calculation in the deSign ofoverhead line,the wind speed should be determined Firstly.Presently,the method usedin our country to determine the maximum wind speed is from former USSR,which developed in 1950s.Some problems still exist in the original material collection and thestatistic calculation.The tower failures are happened frequently,thus take a great lossto the power system.This paper analyzes the problems on wind speed determination.An on-line wind meter controlled by a micro-computer is developed to record theoriginal wind speed data.The design of the meter and the method to measure corridorWind are introduced.The operation results are good.
