  1. 1. Sustainable Production Patterns for Hydropower Units

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Hannington Kayanja; [2023]
    Nyckelord :Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Sammanfattning : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. LÄS MER

  3. 2. Är det möjligt att genomföra miljöanpassade åtgärder vid vattenkraft? : En studie om utrivning av reglermagasin, fiskväg och miljöanpassade flöden i Ljungans vattensystem

    Kandidat-uppsats, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Författare :Erica Roos; [2020]
    Nyckelord :Magazine; Regulation capacity; Flåsjön; Storsjön; Magasin; Reglerkraft; Flåsjön; Storsjön;

    Sammanfattning : Vattenkraft står för stor del av energiproduktionen i Sverige och är nödvändig för elsystemet med sin reglerförmåga. Vattenkraft som inte uppfyller moderna miljövillkor ska komma att omprövas enligt den nationella omprövningsplanen. LÄS MER

  4. 3. Conjunctive Operation of Hydro and Solar PV Power with Pumped Storage at Kafue Gorge Power Station (Zambia)

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Elvis Nyirenda; [2019]
    Nyckelord :Photovoltaic; Hydro; Power; Storage; Pumped Hydro Storage; Zambia;

    Sammanfattning : This report covers the work carried out to redesign the two existing conventional hydro power stations in Zambia on the Kafue river into the pumped storage facility with solar photovoltaic power so that security of supply and water conservation is achieved to reduce the power deficits during the dry and drought periods. The two stations are Kafue gorge upper power station (KGUPS) and Kafue gorge lower power station (KGLPS) with an installed capacity of 990 MW and 750 MW respectively. LÄS MER

  5. 4. On Control and stabilisation of floating wind platforms with the help of CFD analysis and the Magnus effect

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Georg Neumüller; [2017]
    Nyckelord :;

    Sammanfattning : With new technologies and possibilities arising both in the renewable energy sector as well as in the field of Computational Fluid Dynamics, this thesis describes the simulation of vortex- induced vibrations for floating wind turbine platforms. The aim is to control and stabilize floating wind platforms with the help of CFD and the Magnus effect. LÄS MER

  7. 5. Modeling and Optimization of Energy Utilization of Air Ventilation System of an Auditorium

    Master-uppsats, Högskolan i Gävle/Energisystem

    Författare :Kappina Kasturige Kamani Sylva; [2016]
    Nyckelord :Hybrid Ventilation; CFD modeling; Auditorium;

    Sammanfattning : Maintaining IAQ (Internal Air Quality) and thermal comfort of occupants in buildings have been a challenge to overcome satisfying the two ends: criteria for sustainability and cost effectiveness. Although there was a movement for mechanical ventilation systems in the recent past, in addition to the cost involved, they are found to not deliver the desired air quality, lead to social consequences such as sick building syndrome, contribute to environmental consequences related to ozone-depleting substances with increasing energy consumption, generate noise and having difficulties in cleaning and maintaining.
