GIM Model-based Three-dimensional State Fitting of Transmission Lines
In order to accurately observe the deflection of insulator strings under force,this paper studies the implementa-tion of GIM model-based 3 D state fitting of transmission lines.By applying a specifically developed online monitoring de-vice to obtain real-time spatial information of operating wires,orthogonal polynomial fitting technology is used to accu-rately fit wire operating status.In addition,real-time perception of wind deviation and sag of wires under operating condi-tions can be achieved,and the GIM model of transmission lines is used to achieve three-dimensional state fitting of trans-mission lines.The study provides substantial information for subsequent ice monitoring,force load calculation,and tower force stability evaluation.
