Dynamic modeling and vibration control of high-voltage overhead transmission lines
The problem of the dynamic behavior of overhead power transmission lines under wind and other excitations is an important one, since it allows an optimal design and positioning of vibration dampers for the cables. Excessive sway and oscillation of power lines need to be avoided, as they can lead to …

Objective determination of optimal power line designs
… thesis investigated the possibility of overhead power line designs being decided by using an objective rather than a subjective method. Power lines are required to meet criteria for load and transfer capability as specified by system planners which results in many different line design solutions. …
