  1. 16. Rotor dynamical modelling and analysis of hydropower units

    Författare :Rolf Gustavsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : In almost all production of electricity the rotating machines serves as an important part of the energy transformation system. In hydropower units, a hydraulic turbine connected to a generator converts the potential energy stored in the water reservoir into electrical energy in the generator. LÄS MER

  3. 17. Porjus : en vision för industriell utveckling i övre Norrland

    Författare :Staffan Hansson; Luleå tekniska universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Teknikhistoria; History of Technology;

    Sammanfattning : In the late 19th century it became possible to utilize electricity in lighting, industrial processes and for traction. To Sweden, which at that time was gradually being transformed from an overwhelmingly agrarian country into an industrialized nation, this was of great advantage because Sweden was a country well furnished with hydro-electric power, but almost completely lacking in other sources of energy.

  4. 18. Development of the Pressure-Time Method for Flow Rate Measurement in Hydropower Plants by Numerical Simulation

    Författare :Simindokht Saemi; Michel Cervantes; Thomas Staubli; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydropower is a clean and sustainable energy resource developed since the late 19th century. To specify the hydraulic performance characteristics of hydraulic turbines, the volumetric flow rate as one of the few basic quantities should be determined. Discharge represents the most difficult quantity to measure. LÄS MER

  5. 19. Electrification of rural Mozambique : Sustainable energy solutions

    Författare :Miguel Meque Uamusse; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; hydropower potential; Rural electrification; mini-grid; biomass; climate change effects;

    Sammanfattning : The UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. The effects on socioeconomic development by access to safe, affordable, and clean electricity stands out as educational benefits, income improvement, and health progress. LÄS MER

  7. 20. Studies of Transient and Pulsating flows with application to Hydropower

    Författare :Joel Sundström; Michel Cervantes; Mehdi Seddighi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent flows; Pipe flow; Unsteadiness; Friction modeling; Strömningslära; Fluid Mechanics;

    Sammanfattning : The rotational motion of a hydraulic turbine runner makes pulsating flows ubiquitous in different locations of the machine. The cyclic loading thus induced may generate large pressure forces acting periodically on both stationary and rotating parts. LÄS MER
