  2. 1. Assessment of Interruption Costs in Electric Power Systems using the Weibull-Markov Mode

    Author : Jasper van Casteren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semi-Markov model; interruption cost; power system reliability; customer damage function; duration distribution; reliability worth;

    Abstract : Modern competitive electricity markets do not ask for power systems with the highest possible technical perfection, but for systems with the highest possible economic efficiency. Higher efficiency can only be reached when accurate and flexible analysis tools are used. READ MORE

  4. 2. Component reliability importance indices for maintenance optimization of electrical networks

    Author : Patrik Hilber; Roland Eriksson; Lina Bertling; Gerd Kjolle; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; Reliability Importance Index; Maintenance Optimization; Asset Management; Customer Interruption Cost; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Monte Carlo Simulation; Elkraftteknik; Electric power engineering; Elkraftteknik;

    Abstract : Maximum asset performance is one of the major goals for electric power system managers. To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. READ MORE

  5. 3. Maintenance optimization for power distribution systems

    Author : Patrik Hilber; Lina Bertling; Roland Eriksson; Lalit Goel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability Importance Index; Multiobjective Optimization; Maintenance Optimization; Asset Management; Customer Interruption Cost; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Monte Carlo Simulation; Evolutionary Particle Swarm Optimization.; Electric power engineering; Elkraftteknik;

    Abstract : Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. READ MORE

  6. 4. Varicose Veins : Aspects on Diagnosis and Surgical Treatment

    Author : Lena Blomgren; David Bergqvist; Gunnar Johansson; Lars Norgren; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Varicose veins; Venous insufficiency; Surgery; Duplex; Quality of life; Cost analysis; Kirurgi; Surgery; Kirurgi;

    Abstract : Treatment for varicose veins (VV) is insufficiently evidence based and recurrence rates are high. The aim of this thesis was to study the long-term results after VV surgery, risk factors for recurrences and the effect of preoperative duplex scanning on recurrence rate, quality of life (QoL) and costs.

  7. 5. Risk-based methods for reliability investments in electric power distribution systems

    Author : Karin Alvehag; Lennart Söder; Kjølle Gerd; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distribution system reliability; risk management; quality regulation design; customer interruption costs; weather modeling; Monte Carlo simulations; Electric power engineering; Elkraftteknik;

    Abstract : Society relies more and more on a continuous supply of electricity. However, while underinvestments in reliability lead to an unacceptable number of power interruptions, overinvestments result in too high costs for society. READ MORE
