  3. 17. Analysis of Prerequisites for Connection of a Large-Scale Photovoltaic System to the Electric Power Grid

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

    Author : Fanny Lilja; [2021]
    Keywords : solar energy; large-scale photovoltaic system; PV; Swedish power system; power output fluctuations; voltage quality; voltage variations; reactive power compensation; PSS E; solenergi; storskalig solcellsanläggning; PV; Sveriges kraftsystem; effekförändringar; spänningskvalitet; spänningsvariationer; reaktiv effektkompensering; PSS E;

    Abstract : The deployment of large-scale photovoltaic (PV) systems is rising in the Swedish power system, both in quantity and in system size. However, the intermittent characteristics of the PV production raises questions concerning the stability in the electric power grid, and power output fluctuations from the PV systems can lead to voltage quality issues.

  6. 20. Optimal Demagnetization of Transformer After Winding Resistance Measurements

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

    Author : Niclas Grönström; [2020]
    Keywords : ;

    Abstract : In this thesis, transformer demagnetization in connection to winding resistance tests is investigated. In transformer testing, winding resistance measurement (WRM) is an important test used to detect winding or connection faults. It is common practice to measure the resistance by injecting a DC current into the windings of a transformer. READ MORE
