Multiple failures of transmission lines caused by climatic/atmospheric impact plague many electric power systems. Direct damage from such is quite huge, yet it marginal compared with the social reduction in supply electricity. As not economical to construct weatherproof lines, preventive actions should be employed most effective restoration, or reduce restoration time. A working group CIGRÉ (WG...

Abstract This article concentrates on the interconnected past, present and future of telecommunications environment in Arctic. It brings together discussions natural environment, sustainable development connectivity through Arctic focuses fixed-line infrastructure. study builds theoretical literature infrastructure, infrastructuring pipeline ecologies demonstrates how peculiar features Arctic, ...

This paper presents the concept of green telecommunication networks and provides information about the power consumption within fixed line and wireless communication networks. It outlines the significance of energy efficiency in modern and future telecommunication networks and suggests directions for optimizing network performance in terms of energy demands. Numerous examples and reviews are al...

in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...

The digital revolution holds great promise for prosperity and progress. However, the Information Society evolution is supported through the telecommunication networks deployment. The high cost of such infrastructures forces the companies to focus their efforts in the profitable society sectors. For that, the promotion of performances to bridge the digital divide between rural and urban areas ap...

We address the problem of failure diagnosis in discrete-event systems such as telecommunication networks. We propose to extend the decentralized diagnosis approach proposed in (Pencolé 2000) in order to use it in an incremental way. The incremental approach is needed in order to provide on-line diagnosis and assist supervision operators. The difficulties about the incremental decentralized diag...

In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...
