Asset managers in electricity distribution companies generally recognize the need and the challenge of adding structure and a higher degree of formal analysis into the increasingly complex asset management decisions. This implies improving the present asset management practice by making the best use...

A reactive transverse fuel jet in cross-flow (JICF) configuration is studied using three-dimensional direct numerical simulation (DNS) with detailed chemical kinetics in order to investigate the mechanism of flame stabilization in the near field of a fuel jet nozzle. JICF configurations are used in...

EU's RES-E targets for 2020 and the corresponding national action plans will connect large amounts of non-controllable renewable power generation to the grid, if plans are implemented. This gives increased need for production technologies that easily can balance demand with supply at moderate costs...

This report addresses state of the art in the field of transformer ageing and diagnostics, with emphasis on advising end-users on transformer asset management and on transformer specification. The basis is results from two projects on laboratory studies on ageing of mineral oil impregnated cellulose...

This paper addresses the methodological issues related to data normalization and the estimation of customer average interruption costs that are suitable for incorporation into performance-based regulation regimes. The paper describes methods and algorithms developed to calculate individual and...

Balancing cost-effectiveness and quality of service is one of the most important tasks for network companies in the deregulated environment. It is widely recognized that interruption costs is a relevant expression for the inconvenience customers feel when service is interrupted and that adequate...

Correct operation of the protection system is of vital importance for the reliability and security of supply. Information of protection system faults is therefore important for different purposes such as quality of supply regulation and as input data to security and reliability analysis. This paper...

It is a question of concern if - and how - the vulnerability of the electric power grid and probability of interruptions is increasing as assets are ageing and components are being utilized closer to their limits. These aspects may have severe long-term consequences which it is of vital importance...

In this paper, an experimental verification of the control of a modular series connected voltage source converter suitable for an HVDC transformerless offshore wind turbine is presented. The test bench is built around a 45 kW special generator prototype with three stator segments. Three 20 kW...

Carbon Capture and Storage (CCS) is an important part of a carbon-constrained energy scenario to reduce global emissions. Most of the present works in literature related to CO₂ capture assumes exhaust stream from power plants, as they represent large CO₂ volume sources, and consider steady flow of...
