Study on the Frequency Response of Overhead Transmission Lines

The goal of this project is to research and develop a model that is suitable for BC Hydro’s application to predict the sag of a power transmission line from its induced frequency response. Transmission lines always elongate over time due to the temperature of the conductor. The ability to monitor and obtain the shape of transmission lines is one of the most important tools in evaluating power transmission line’s effectiveness in operation, maintenance and the most important, safety. This project will be done by doing a thorough literature survey and using existing models on cable dynamics with appropriate assumptions, and then apply these models to transmission lines vibrational pattern.
