  1. 1. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment

    Author : Per Westerlund; Patrik Hilber; Tommie Lindquist; William Q Meeker; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reliability; maintenance; condition monitoring; disconnector; circuit breaker; Weibull distribution; prediction; risk analysis; decision making; beta distribution; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The supply of electricity is important in modern society, so the outages of the electric grid should be few and short, especially for the transmission grid. A summary of the history of the Swedish electrical system is presented. The objective is to be able to plan the maintenance better by following the condition of the equipment. READ MORE

  2. 2. On Risk Management of Electrical Distribution Systems and the Impact of Regulations

    Author : Carl Johan Wallnerström; Lina Bertling; Roland Eriksson; Kjell Sand; KTH; []

    Abstract : The Swedish electricity market was de-regulated in 1996, followed by new laws and a new regulation applied to the natural monopolies of electrical distribution systems (EDS). These circumstances have motivated distribution systems operators (DSOs) to introduce more comprehensive analysis methods. READ MORE

  3. 3. Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards

    Author : Nicholas Honeth; Lars Nordström; Valeriy Vyatkin; KTH; []

    Abstract : The electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.

  4. 4. Opportunistic Content Distribution : Feasibility, Design and Performance Evaluation

    Author : Ólafur Helgason; Gunnar Karlsson; Cecilia Mascolo; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : Originally, the main purpose of the wired Internet was to interconnect hosts on different networks in order to allow them to communicate. Although this is still an important service, the Internet has evolved and today its predominant application is to provide its users with access to contents. READ MORE

  5. 5. Distribution Preserving Quantization

    Author : Minyue Li; W. Bastiaan Kleijn; Jan Østergaard; KTH; []

    Abstract : In the lossy coding of perceptually relevant signals, such as sound and images, the ultimate goal is to achieve good perceived quality of the reconstructed signal, under a constraint on the bit-rate. Conventional methodologies focus either on a rate-distortion optimization or on the preservation of signal features. READ MORE
