Abstract
A methodology for design of magnetorheological dampers for damping vibration of overhead power lines with voltages above 110 kV is proposed, which includes a finite element model of the behavior of the working magnetorheological fluid in a hydraulic channel, and a Matlab model of dynamic processes in a loaded damper. This technique uses tables of damping coefficient values instead of the hysteretic displacement variable characteristic of the Bouc–Wen model, i.e., they use variables and parameters with a physical meaning, known at the stage of formulating technical requirements or determined by calculations. To verify and evaluate the accuracy of the technique, a vibration model of a section of AC 150/19 wire is studied as a system with lumped parameters, suspended on garlands of intermediate support insulators using magnetorheological dampers.
