Algorithm Research on Icing Load Detecting for the Overhead Transmission Line

摘要

In this paper, the icing mechanism and force of overhead transmission lines were studied. The inclined parabolic equation of overhead transmission lines was derived and on this basis, calculation methods of sag, long lines and stress had been discussed. The paper got the inclined parabolic form of the equation of state based on the relationship between the different states of overhead lines and overhead transmission line icing load detection algorithm which combined with measured climate parameters, coordinate data and wire parameters. This paper made simulation experiment according to overhead transmission line icing load algorithm proposed verifying the correctness of the ice load detection algorithm.
