Abstract:

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 algorithm based on the Cartesian coordinates.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 skewing shows that the proposed algorithm is sensitive to the foundation of towers,and has a good monitoring and early warming performance.
