摘要
输电杆塔在输电网络中具有极其重要的地位,其稳定可靠性直接关系到电力网络的安全运行。为了准确掌握孤堡输电杆塔的运行状态,提出了以笛卡尔坐标系为基准的孤堡输电杆塔基础偏移算法。通过实际塔基结构构建模型进行实验分析和验证,结合实验数据设计了基于LabVIEW的孤堡输电杆塔基础位移监测系统。从得出的24组采样点与基础位移变化关系曲线可知,提出的算法对塔基支撑脚感应灵敏,系统对输电杆塔基础偏移具有较好的监测预警作用。
The towers of transmission lines play an important role in transmission network, and its stability and reliability directly related to the safe operation of the power network. For accurate control of transmission towers＇operation,we propose an skewing monitoring aigorithm based on the Cartesian co- ordinates. We analyze and validate our algorithm through an experiment on an actual structure building model. We also design a real-time monitoring interface based on LabVIEW combined with experimental data. The obtained relationship curve between the 24 groups of sample points and the fundamental ske- wing shows that the proposed algorithm is sensitive to the foundation of towers,and has a good monito- ring and early warming performance.
