  1. 1. Hydrostatic transmission in wind turbines : Development of test platform

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Joel Rapp; Jonatan Turesson; [2015]
    Keywords : Wind turbine; Hydrostatic transmission; Test platform; Maximum power tracking; Hydraulic system;

    Abstract : This master thesis project is a part of a larger project with the goal of develop-ing a drivetrain, utilizing a hydrostatic transmission, for horizontal axis mid-sizewind turbines. Some of the benefits from using a hydrostatic transmission are thata variable speed operation is possible without the use of a frequency converter,the generator may be placed on the ground and thus reduce weight in the nacelleand also using hydraulic components can increase lifetime and robustness of thesystem.

  3. 2. Design of a PV system with variations of hybrid system at Addis Ababa Institute of Technology

    University essay from KTH/Energiteknik

    Author : Lovisa Bergman; Amanda Enocksson; [2015]
    Keywords : ;

    Abstract : This paper proposes a renewable power generation system for Addis Ababa Institute of Technology (AAiT). The aim of hybridizing renewable energy sources is that the main load shall be covered by the available solar energy source and other sources shall function as a complement when there is a deficiency in the main source.

  4. 3. Influence of damping winding, controllersettings and exciter on the damping of rotorangle oscillations in a hydroelectric generator : The testing of a mathematical modell

    University essay from Elektricitetslära

    Author : Jonathan Hanning; [2011]
    Keywords : Mathematical model; generator; angle oscillation;

    Abstract : This thesis has been performed in the university context for Master thesis 30 credits,which is a compulsory exercise in order to gain a degree in electrical engineering. The thesis main objectives were to investigate how the damping and the stiffness of ahydroelectric generator changed depending on different parameter values, and to testa new mathematical model to calculate the damping and stiffness constants Kd and Ks.
