  1. 1. Towards Intelligent Power-System Monitoring: Segmentation, Feature Extraction, and Identification of Underlying Causes

    Author : Cuong Le; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; harmonics analysis; Power-system monitoring; segmentation; power-system measurement; power quality; event analysis; signal-processing applications;

    Abstract : The increase in size of modern power systems together with the concept smart grid requires advanced monitoring to ensure system availability, reliability, and power quality. The huge amount of available data no longer permits analysis to be implemented manually and centrally. READ MORE

  2. 2. Wind-turbine harmonic emissions and propagation through a wind farm

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kai Yang; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; Electric power system; Wind power; Power quality; Power system harmonics; Technology - Electrical engineering; electronics and photonics; Teknikvetenskap - Elektroteknik; elektronik och fotonik; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

    Abstract : The increasing demand for sustainable energy is one of the driving forces behind the increasing use of wind power by means of wind-turbines in electric power systems. Modern wind turbines commonly employ variable-speed-generator technology associated with a power-electronic converter as part of the grid connection. READ MORE

  3. 3. Power Measurement Techniques for Nonsinusoidal Conditions. The Significance of Harmonics for the Measurement of Power and other AC quantities

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Stefan Svensson; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-sinusoidal; reactive; harmonics; power; sampling wattmeter;

    Abstract : The increased application of power electronics and other non-linear loads makes it necessary to re-evaluate the measuring techniques used in the power system, and the measuring problems these loads cause. An instrument utilising digital sampling techniques has been built and evaluated at the Swedish National Testing and Research Institute (SP). READ MORE
