  1. 21. Power Loss Evaluation of Submarine Cables in 500 MW Offshore Wind Farm

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lahiru Kushan Jayasinghe; [2017]
    Keywords : Power Loss; Offshore Windfarm; Submarine Cables; HVAC; HVDC LCC; HVDC VSC; MATLAB Simulink;

    Abstract : The main objective of this thesis is to develop a new methodology to evaluate the transmission cable losses of wind-generated electricity. The research included the power loss variations of submarine cables in relation to the line length, cable capacity and the transmission technology in an offshore wind farm having a capacity of 500 MW.

    Author : Olof Brandt Lundqvist; [2017]
    Keywords : ;

    Abstract : Wave power is an energy source which could make a decisive difference in thetransition towards a more sustainable energy sector. The growth of wave powerproduction has however not been as rapid as the growth in other renewableenergy fields, such as wind power and solar power. READ MORE

  5. 24. A New Cell Bypass Arrangement and Control for Modular Multilevel Converters based on Thyristor Forced Commutation Circuit

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Soteris Poyiadjis; [2017]
    Keywords : ;

    Abstract : HVDC transmission lines are a competitive and in some cases are proven to bea superior choice compared to AC transmission applications. Suitable convertershave been developed for that matter where Modulär Multilevel Converters (MMC)are highly preferred due to their low losses, no filtering requirementsand direct andfast control of AC and DC side.
