基于拉V塔测量法的局部微天气电网预警系统设计
|
摘要
针对当前输电线路受天气变化影响较大这一现象,本文将对基于拉V塔测量法的局部微天气电网预警系统进行设计。在设计过程中,首先从该系统设计思路以及使用的关键技术入手,在提出具体设计思路之后,对振动频谱与张力关系模型进行构建,从而通过该模型为后续传感器测量提供支持。在此基础上,分别对振动检测与传输系统、无线数据采集系统等进行设计,并给出测试结果。通过以上的研究,旨在为输电线路管理工作提供参考。
In view of the phenomenon that the current transmission line is affected by the weather change greatly,this paper will design the local Micro Weather Network Warning System Based on the pull V tower measurement method.In the process of design,first of all,starting with the design idea of the system and the key technology used,the relationship model of vibration spectrum and tension is constructed after the concrete design idea is put forward,so as to provide support for the follow-up sensor measurement through the model.On this basis,vibration detection and transmission system,wireless data acquisition system and so on are designed respectively,and the test results are given.Through the above research,the purpose is to provide reference for transmission line management.
