  1. 6. Variable speed drive as an alternative solution for a micro-hydro power plant

    Master-uppsats, KTH/Elektrisk energiomvandling

    Författare :Malik Usman Akhtar; [2012]
    Nyckelord :;

    Sammanfattning : This diploma work is mainly focused on developing the control strategy for avariable speed drive as an alternative solution to a micro-hydro power plant. The detailed mathematical model for a micro-hydro system including a Kaplan turbine, mechanical shaft and electrical machines is presented and validated through simulations. LÄS MER
