The protagonist is the Lule River, where the implications of its domestication and agency is explored. READ MORE

  4. 3. Numerical simulations of the pressure time method in a full-scale turbine

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Hugo Jönsson; [2019]
    Keywords : ;

    Abstract : Efficiency measurements are an important part of operating and maintaining a hydroelectric turbine. In order to calculate the efficiency, one need a method to accurately measure the flow rate. The pressure time method is a way to calculate the flow rate from pressure measurements, which are done during a transient. READ MORE

  5. 4. Preliminary simulation of Porjus U9 turbine at speed no load

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Henrik Holmström; [2019]
    Keywords : Kaplan; Speed no-load; SNL;

    Abstract : Hydropower plants are shifting towards operating at off-designed conditions, meaning that the number of start-stop cycles and maintenance time due to cavitation increases. The speed no-load condition is the moment before magnetization of the generator, i.e., no load, low flow, constant runner rotational speed, guide vane and runner blade angle. READ MORE
