This research aims to develop data-driven methods that automatically exploit historical data in smart distribution grids for reliability evaluation, i.e., analyzing frequency of failures, and modeling components’ lifetime. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from historical data. In particular, the da...

EeFarm-II is used to evaluate 13 different electrical systems for a 200 MW wind farm with a 100 km connection to shore. The evaluation is based on component manufacturer data of 2009. AC systems are compared to systems with DC connections inside the wind farm and DC connection to shore. Two options have the best performance for this wind farm size and distance: the AC system and the system with...

The sustainability of power infrastructures depends on their reliability. One test of the reliability of an infrastructure is its ability to function reliably in extreme environmental conditions. Effective planning for reliable electrical systems requires knowledge of unscheduled outage sources, including environmental and social factors. Despite many studies on the vulnerability of infrastruct...

This paper describes the use of particle filters for visual tracking of underwater elongated structures such as cables or pipes. Models for probabilistic tracking are obtained directly from real underwater image sequences. Extensive experiments on realistic underwater videos of power cables installed almost 30 years go (i.e. they cannot be easily discriminated from the background) show the robu...

The demand and necessity of direct current (DC) has been increasing owing to large capacity long distance power transmission. DC application TP (thermal plastic) materials, which can increase the transmission compared existing insulation primary focus studies. This study presents development a highly reliable accelerated aging system that implement conditions cables. Moreover, we verify its rel...

A cable configuration technique for the balance of current distribution in parallel-connected single-core cables is proposed. Based on the mutual inductance theorem, a closed form solution for the calculation of current distributions in parallel-connected cables is first derived. To compare the performances of different cable configurations, two indices are introduced, one for the power losses ...

Exchange of information is essential in any society and the demand for faster, cheaper, and secure communications is increasing every day. With other hi-tech initiatives like IPv6 and Internet-of-Things (IOT) already in the horizon, demand for broadband is set to escalate beyond its current level. Inherently laden in the challenges posed by this technology are fresh opportunities in terms of pe...
