  1. 11. Analysis of atmospheric influences on ratio thermography for solar tower systems

    University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Author : Albin Englin; [2022]
    Keywords : Concentrated solar power; Ratio thermography; Shortwave infrared; Gray body assumption; Atmospheric compensation;

    Abstract : The knowledge of temperature and emissivity of the receiver are both critical for a solar tower power plant, in order to guarantee an efficient operation of the thermal receiver on the one hand, while monitoring any degradation of the receiver coating on the other hand. To make these measurements, a new thermographic system is currently being developed, using a multispectral camera working in the short wavelength infrared spectrum. READ MORE

    Abstract : To meet the aims of the Paris climate agreement, it is necessary to reduce energy use in buildings. Efficient HVAC systems are a critical part in achieving a low delivered energy use. READ MORE

  4. 13. Evaluation of Symmetrical Components Theory in Power Systems with Renewable Sources

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Daniil Danylov; [2021]
    Keywords : Symmetrical components theory; fault analysis; renewable sources; power electronics; PSCAD EMTDC; two bus system; inverter-based resources; line protection; nonlinear source.; Teori om symmetriska komponenter; felanalys; förnybara källor; kraftelektronik; PSCAD EMTDC; tvåbussystem; inverterbaserade resurser; linjeskydd; icke- linjär källa.;

    Abstract : Rapidly growing Inverter- Based Resources (IBR) have different fault properties compared to Synchronous Generators (SG). Therefore, it is necessary to study the fault behavior of systems that contain different types of IBR and compare it to the conventional system responses in order to understand what steps should be taken to adapt conventional protection settings for new types of sources.
