    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Nicklas Hillgren; [2011]
    Nyckelord :Hydropower; pressure transients; full column separation; large cavities; reverse waterhammer; Vattenkraft; trycktransienter; separation av vattenpelare; vattenslag; större kaviteter;

    Sammanfattning : Hydropower plants have the ability to go from a full load to no load in just a fewseconds. In order to go from full load to no load in a few seconds the flow iscontrolled by movement of guide vanes. At fault detection the guide vanes closesquickly for safety reasons. LÄS MER
