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

    University dissertation from Stockholm : Elektrotekniska system

    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

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kai Yang; Luleå tekniska universitet.; [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

  4. 4. Dynamic Analysis of Harmonics in Electrical Systems

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Erik Möllerstedt; Lunds universitet.; Lund University.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; converter control; modeling; linear time periodic systems; frequency domain analysis; harmonics; power systems; small signal stability; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Frequency domain analysis and design of power systems is complicated in the presence of harmonics, switching dynamics, nonlinearities, unbalances, and for systems with mixed ac/dc dynamics. The reason is that linearization of the system does not lead to a time invariant system, but a system with periodically time varying dynamics, which implies that there is coupling between different frequencies.
