Wire Motion Induced Ice Falling

Popis výsledku v původním jazyce

This paper deals with dynamical model of overhead line. The main reason to study these problems is to create power line overloading model. The dynamic catenary based model is also useful for modelling of dynamics states caused by weather (such as temperature changes, snow etc). There is shown how this model has been created; its properties are clarified and compared. Equations describing the dynamic behaviour of the component are shown. The important part of study is simulation on three related spans. Between spans can wire move and wire tension is depending on excitation forces. Multi-span model are used for many different simulations where thick of ice and falling ice part are changed. Dynamics model is also validated in steady state and simulated data are compared with real spans. Case studies focus on difference between minimal and maximal sag during transient for each span.
