  1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

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

    Author : Muhammad Umar Farooq; [2023]
    Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces.

  3. 2. Unlocking the Potential of Battery Energy Storage Systems in the Nordic Frequency Regulation Markets : A techno-economic analysis to evaluate long-term profitability

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Theodor Ingman; Henrik von Sivers; [2023]
    Keywords : ;

    Abstract : As the Swedish power system has increased its shares of production coming from intermittent renewables, the production coming from large rotational units as nuclear, and hydropower, has decreased. Thereby, the power system has become more sensitive to sudden changes between production and consumption of electricity, increasing the risk of disruptions in the electricity grid. READ MORE

  4. 3. Efficiency of radial piston hydraulic motors

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jennifer Eriksson; [2023]
    Keywords : Efficiency; Loss mechanics; MATLAB; Simulation model; Radial piston hydraulic motor;

    Abstract : In a world with high energy cost, the efficiency of motors becomes increasingly important. Thereby, the understanding of loss mechanics is of great significance and having accurate simulation models for the efficiency of motors is crucial. READ MORE

  5. 4. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

    University essay from Uppsala universitet/Elektricitetslära

    Author : Benjamin Hedlund Peters; Linda Goude; [2023]
    Keywords : wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

    Abstract : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.
