  1. 1. A DSO-driven evaluation of a CIM profile : Development of a CIM profile based on use cases related to monitoring Vattenfalls low voltage network

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Louise Persson; [2022]
    Keywords : ;

    Abstract : The transition to more renewable energy sources places high demands on the power systems to be more flexible, and makes it grow in complexity. This has led to a growing need of a common format or language for data exchange in power systems because of the growing number of interconnected networks operated by different companies and utilities that need to communicate on a daily basis.

  3. 2. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

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

    Author : Hjörtur Brynjarsson; [2021]
    Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

  4. 3. Emergency Power for Wind Turbine Yaw System - Project initialization tool

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Vigan Spahiu; [2020]
    Keywords : Technology and Engineering;

    Abstract : The Yaw Power Backup System (YPBS) is a safety system that needs to be incorporated in the Wind Power Plant (WPP) in order to provide emergency power during a power outage. The YPBS enables the Wind Turbine Generator (WTG) to perform a yawing operation in extreme weather conditions. READ MORE

  5. 4. Eliminating zero-missing phenomenon in long, high voltage, underground cables

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

    Author : Agnes Linnet; [2019]
    Keywords : Underground cable; zero-missing phenomenon; switching transients; shunt reactors; underexcited generators; Underjordisk kabel; nollbristande fenomen; växlingstransienter; shuntreaktorer; underexiterad generatorer;

    Abstract : The maximum length of an high voltage underground cable (HV UGC) cable is oftenconstrained by the criterion that the cable cannot have more than 50% reactivepower compensation. If this limit is exceeded the current in the circuit breaker maynot have a zero crossing after energization, which is referred to as the zero missingphenomenon. READ MORE

  6. 5. The Emergence and Compensation of Reactive Power in the North Western Province of Zambia

    University essay from Uppsala universitet/Elektricitetslära

    Author : Matthew Koenig-Barron; [2017]
    Keywords : reactive compensation; Zambia; transformer; powerworld; shunt reactor; long line model;

    Abstract : The design of a transmission project is as varied in the factors that affect it as the people to which the project supplies electricity. This thesis focuses on the theoretical considerations in the design process that affect the emergence of reactive power in a system and how reactive compensation is achieved. READ MORE
