Lightning Induced Overvoltages in Mixed 380 kV OHL-Cable-OHL connections

Transmission of electric energy at high voltage levels is mainly performed by overhead lines. Nowadays, an increasing amount of power grid operators are replacing overhead transmission lines by underground cables. Cable presence in power systems may have consequences for the behavior of the total system, since cables have much larger capacitance...

Understanding the dynamics of broadband markets: A comparative case study of Flanders and the Netherlands

The Digital Agenda for Europe sets out clear goals for providing high speed broadband to all its residents, but leaves the implementation of this plan to the individual Member States. Because of large economic, cultural and political differences, the roads to realizing these ambitious goals are varying in between these Member States. This paper...

A multi-body dynamics approach to a cable simulator for kites

For the purpose of ultimately building a fully dynamic simulation of kites, an investigation is launched into a viable model of the cable with which the kite is attached to the ground. In the model proposed in this paper, only the slow modes of motion are taken into account due to the fact that only the slow motions have a real effect on the...
