  3. 7. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system

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

    Author : Sidharth Kapoor; [2022]
    Keywords : Melting of Ice; Numerical modeling; Transient conjugate heat transfer; Transient analysis; CFD; Switch heating; Heat pumps in Railways; Issmältning; Numerisk modellering; Transient värmeöverföring; Transientanalys; CFD; Värmepumpar i järnvägar;

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE

  4. 8. Elimination of Harmonic Disturbances in Softstarters

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Abstract : As modern electronics have started to reach its physical scaling limits, novel architectures and physics is needed to meet future demands. Oxide-based Resistive Random Access Memory (RRAM) is a new emerging technology that uses filament formation and rupture in thin oxides to generate resistive switching. READ MORE

  6. 10. Optimization of a battery energy storage system : For utilization of peak shaving and fast frequency reserve

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Robert Sundgren; [2020]
    Keywords : battery energy stroage system optimization;

    Abstract : As Sweden switches to increasing renewable electricity production the demand on the energy grid and energy market will become higher. Since a bigger part of the electricity consumption will come from flowing energy sources the production will become less stable and harder to plan with the consumption. READ MORE
