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

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Per Westerlund; KTH.; [2017]
    Keywords : 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

    University dissertation from Stockholm : KTH

    Author : Carl Johan Wallnerström; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Distribution System; Maintenance Management; Project Planning; Regulation; Reliability Analysis; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Risk Analysis; Risk Management; Risk Methods; the Network Performance Assessment Model NPAM ; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    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. Risk and Vulnerability Analysis of Large Scale Technical Infrastructures - Electrical Distribution Systems

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Jonas Johansson; Lund University.; Lunds universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The thesis treats the subject of risk and vulnerability analysis of large-scale technical infrastructures. In particular the focus is on the development of methods for vulnerability analysis of electrical distribution systems. The methods and the concepts behind them should nevertheless also be seen as applicable to other technical infrastructures. READ MORE

  4. 4. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Ingmar Leisse; Lund University.; Lunds universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

    Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE
