输电铁塔塔身光纤光栅结构监测与时序融合研究
Research on Structure Monitoring and Sequence Fusion of Transmission Towerbody Based on FBG
摘要
Abstract
Transmission towers are usually located in complex geological structure areas. Tower crushing and dump⁃ing may occur under the effect of different geological hazard,wind action and other phenomena which is a serious threat to the stable operation of the power system. Conventional manual inspectionis a greateconomic loss,the prob⁃lems can't be found in time either. Analysis and obtaining the strain distribution on transmission tower with a cross arm in the form of three straight double-circuit byANSYS. Obtaining the strain data by an online monitoring system of transmission tower based on FBG sensor network. 4 FBG strain sensors’sample data were fused by the method of batch estimation and weighted average time series analysis and processing based on the standard deviationin the past six months. The fusion values of 4 FBG strain sensors are:61.67με,61.37με,61.97με,61.82με. The fusion values can be used to improve the accuracy of damage identification. Conventionalmanual inspection method is improved.关键词
