The Overhead Cable Crossing

Influence of differences between cable system and overhead lines

One way to increase distribution network reliability is to replace traditional overhead lines with underground cables. To fully utilize these investments, network owners will have to adjust their reliability engineering methods to suit the new cable networks. In this paper different condition assessment methods as well as improved failure statistics for cable systems are considered. The paper i...

Layer-crossing overhead and information spreading in multiplex social networks

application of s-transform for fault location in combined overhead line and cable distribution networks

this paper illustrates the application of s-transform and continuous wavelet transform (cwt) for fault location in combined overhead line and cable distribution networks. the high frequency transient signals originated by faults are analyzed using s-transform and cwt. the s-transform is found to be applicable in transient based fault location in distribution networks. this technique is an expan...

Exponential stabilization of an overhead crane with flexible cable via a back-stepping approach

This paper deals with the uniform exponential stabilization of a hybrid PDE}ODE system which describes an overhead crane with #exible cable. A previous linear boundary feedback law (see d'AndreH a-Novel, Boustany, Conrad & Rao (1994). MCSS Journal, 1, 1}22) depending on the platform position and velocity and on the angular displacement of the cable at the connection point to the platform, led t...

Adaptive sliding mode control of overhead cranes with varying cable length

An overhead crane transports cargoes of various weights and volumes depending on the operation case. Friction factors characterized by damped coefficients are changeable in terms of the operating environment. In this study, an adaptive version of the sliding mode control of a crane system is developed in the case of no priori knowledge of the payload mass and damped elements. Using two inputs, ...
