  1. 1. Computational framework for studying charge transport in high-voltage gas-insulated systems

    Author : Shailendra Singh; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drift diffusion equation; gaseous dielectrics; high voltage; gas discharge; low temperature plasma; streamer propagation;

    Abstract : Increasing demands in electric energy stimulates a shift in functional requirements to power distribution networks and pushes equipment manufacturers to develop highly optimized products where high rated parameters (e.g., energy, voltages) are combined with reduced geometrical dimensions of components.

  2. 2. The Effects of Lightning on Low Voltage Power Networks

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Raul Montaño; Uppsala universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Lightning induced effects; Lightning Electromagnetic fields; Electromagnetic Compatibility EMC ; Surge Protective Devices SPDs ; Low voltage power networks; Elektroteknik; elektronik och fotonik; TECHNOLOGY Electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik;

    Abstract : The present society is highly dependant on complex electronics systems, which have a low damage threshold level. Therefore, there is a high risk of partial or total loss of the system’s electronics when they are exposed to a thunderstorm environment. READ MORE

  3. 3. Integration of Wind Power in Medium Voltage Networks - Voltage Control and Losses

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ingmar Leisse; Lunds universitet.; Lund University.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Since some years ago greenhouse gases and especially carbon dioxide have become one of the most widely debated issues. To reduce the emission of carbon dioxide and nuclear waste, renewable energy sources as for example wind power plants have become very successful. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

    Abstract : Popular Abstract in Swedish Målet med arbetet var att öka mängden vindkraft, solel och annan distribuerad generering (DG) som kan anslutas till befintliga distributionsnät på ett snabbt och kostnadseffektivt sätt. Att införa aktiv spänningsreglering i nätet, istället för installation av nya ledningar, har identifierats som en lämplig strategi. READ MORE

  5. 5. On Tracing Flicker Sources and Classification of Voltage Disturbances

    University dissertation from Department of Signals and Systems, Chalmers University of Technology

    Author : Peter Axelberg; Högskolan i Borås.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transmission and distribution; digital signal processing; power quality monitoring; light flicker; power system disturbance; support vector machines; Medicinteknik; voltage dips; voltagedips; Support Vector Machines;

    Abstract : Developments in measurement technology, communication and data storage have resulted in measurement systems that produce large amount of data. Together with the long existing need for characterizing the performance of the power system this has resulted in demand for automatic and efficient information-extraction methods. READ MORE
