    Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE

  3. 3. Converter Interfaced Distributed Generation - Grid Interconnection Issues

    Author : Fainan Magueed; Chalmers University of Technology; []
    Keywords : VSC; harmonics; LCL-filter; power quality; weak grid; voltage regulation; vector control; strong grid; distributed generation; intentional islanding; L-filter; voltage dips;

    Abstract : Distributed generation (DG) with a converter interface to the grid is found in many of the green power resources applications. In this thesis, the control of a voltage source converter (VSC), as the DG front end, is in focus regarding the power quality problems that could appear at the connection point. READ MORE

  4. 4. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications

    Author : Jan Svensson; Chalmers University of Technology; []
    Keywords : wind turbine; voltage source converter; voltage angle control; frequency response; vector current control; grid-connected; forced-commutated; measurements;

    Abstract : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. READ MORE

  5. 5. Wind Turbine Characterization by Voltage Source Converter Based Test Equipment

    Author : Nicolas Espinoza; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Grid Integration; Frequency Scan; Discrete Control; Wind Power; Grid Emulation; Voltage Source Converter VSC ; Grid Code; Low Voltage Ride Through LVRT ;

    Abstract : In countries where wind power has become a relevant part of the total generated electrical power, transmission system operators (TSOs) have included in their Grid Codes specific technical requirements for interconnection of wind power plants. Some Grid Codes demand specific testing procedures in order to verify the fulfilment for their requirements. READ MORE
