  2. 2. Design and Assessment of HVDC Off-shore Wind Turbine Generator

    Author : Poopak Roshanfekr; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; annual energy efficiency.; permanent magnet assisted synchronous reluctance generator PMa-SynRG ; high voltage direct current HVDC ; wind energy; finite element method FEM ; maximum torque per ampere MTPA ; interior permanent magnet synchronous generator IPMSG ;

    Abstract : In this work, design and assessment of a 5 MW wind energy generator with a gearbox is performed to find an energy-efficient generator for HVDC offshore wind turbines, studying aninterior permanent magnet synchronous generator (IPMSG) as well as a permanent magnetassisted synchronous reluctance generator (PMa-SynRG). Quantities such as torque density,torque ripple, losses and amount of magnet material are studied. READ MORE
