  1. 21. A review of the use of scientific knowledge in environmental impact assessment reports for dam construction.

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Memory Kamoyo; [2020]
    Keywords : ;

    Abstract : It is estimated that 3,700 major dams are either planned or under construction, notably in developing countries. Dams can pose a threat to fish diversity, as one of the biggest impacts of damming is habitat fragmentation. READ MORE

  3. 22. Testing Project Intervention Logic Against Principles of Technology Transfer: The Case of Two UNIDO Small Hydropower Projects

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Andreea Miu; [2019]
    Keywords : technology transfer; intervention logic; logic models; logic analysis; small hydropower; international development; UNIDO; Earth and Environmental Sciences;

    Abstract : Technology transfer (TT) is a process that allows countries to acquire, adapt, deploy, localise and innovate technologies from other countries. In the case of international development, TT can help enhance the technology capabilities of developing countries and empower them to boost their economic development. READ MORE

  4. 23. Experimental Investigation of Added Mass and Damping on a Model Kaplan Turbine for Rotor Dynamic Analysis

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

    Author : Timmy Nyman; [2018]
    Keywords : Added mass; added damping; rotor dynamics; kaplan turbine; vibrations; fluid dynamics;

    Abstract : The concept of added hydrodynamic properties such as added mass is of importance in modern hydropower development, mainly for rotor dynamic calculations. Added mass could result in reduced natural frequencies and altered mode compared to existing simulation models. READ MORE

  5. 24. Modelling the national electricity system of Rwanda : Contribution to the achievement of Sustainable Development Goal 7

    University essay from KTH/Energiteknik

    Author : CAROLINA NORDSTRÖM; IDA STENBERG FORSBERG; [2018]
    Keywords : Energy; Electricity; Rwanda; OSeMOSYS; MoManI; Sustainable development; SDG 7; Energi; Elektricitet; Rwanda; OSeMOSYS; MoManI; Hållbar utveckling; SDG 7;

    Abstract : För att ett samhälle ska utvecklas på ett modernt och framgångsrikt sätt är elektricitet en grundläggande faktor. Tillgång till elektricitet förhöjer levnadsstandarden för befolkningen genom att generera positiva synergieffekter såsom att fler utbildar sig, ekonomisk tillväxt och stabilitet, förbättrad välfärd och internationella samarbeten.

  6. 25. Construction, testing and verification of a brushless excitation system with wireless control of the field current in a synchronous generator.

    University essay from Uppsala universitet/Elektricitetslära

    Author : Rickard Larsson; Kenny Andersson; [2018]
    Keywords : Brushless excitation; synchronous generator; bluetooth; torque ripple; Borstlös matning; synkrongenerator; blåtand; momentpulsationer;

    Abstract : Synchronous generators have been used in hydropower from more than a century where, traditionally, the field current is transferred to the rotor using slip rings and carbon brushes. There are some major disadvantages following the use static excitation; regular and expensive maintenance, as well as a source of carbon dust which, due to buildup, may cause short circuits. READ MORE
