[en] The paper discusses some aspects of modeling the wake-induced vibrations of the bundle conductors in transmission lines.
The wake coupling between subconductors is modeled with the modified Simpson’s approach. In order to apply this model to the analysis of power transmission line (PTL), a modal representation of a span could be used. In present paper we study how application of Dynamic Reduction (Component Mode) technique may improve such analysis under finite-element approach. The present paper, to extent of authors’ knowledge, is the first where Component Mode method application is discussed to study the subspan oscillation.
Finally, bundled conductors’ susceptibility to wake-induced vibrations is illustrated on an exemplary twin-bundle, three-subspan model. Effects of bundle parameters (initial subconductor spacing, frequency ratio, subconductor mass), and the means to account them when applying the component mode method are discussed.
