  1. 1. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Farsad Mansori; [2022]
    Keywords : Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

    Abstract : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. READ MORE

  3. 2. Turbo For Fuel Cell Electric Vehicle

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Adam Hansson; Mohammed Abu Al-Soud; [2022]
    Keywords : Turbo; Fuel Cell; Centrifugal Compressor; Radial Turbine; Axial Turbine; Technology and Engineering;

    Abstract : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. READ MORE

  4. 3. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.

    University essay from Uppsala universitet/Elektricitetslära

    Author : Alfred Nerby; [2022]
    Keywords : Renewable; Wind; Solar; multi-source; park; collection grid; substation; transmission; HVAC; HVDC; converters; shunt reactors; transformer; losses; CAPEX; OPEX;

    Abstract : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.

  5. 4. Design of a radial-inflow microturbine for combined heat and power generation unit

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Salvador María Beltrán Martínez; [2021]
    Keywords : radial inflow turbine; turbomachinery; rotor; nozzle vanes; reaction; design; TurbAero; CAD; blade speed ratio; specific speed; efficiency; turbine exhaust; turbine; inlet; pressure drop; Euler equation; losses; blade loading plot; pressure side; suction side; Technology and Engineering;

    Abstract : This project aims to design a radial inflow microturbine that will be part of a system to generate both heat and electricity. Considering the specific power and the mass flow rates involved with the system, a radial inflow turbine was chosen. This type of turbine provides much larger power density in a single stage compared to the other types.. READ MORE

  6. 5. Determination of aerodynamic damping at high reduced frequencies

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

    Author : Minghao Pan; [2017]
    Keywords : Aerodynamic damping; reduced frequency; forced response; acoustic mode; acoustic resonance; Aerodynamisk dämpning; reducerad frekvens; aerodynamiskt påtvingade vibrationer; akustiskt svängningsform; akustisk resonans;

    Abstract : Forced response which is blade vibration due to an external excitation can lead to blade failure. The estimation of the level of vibration is dependent on the determination of aerodynamic damping. This thesisinvestigates the determination of aerodynamic damping at high reduced frequencies in turbomachines. READ MORE
