  1. 1. Evaluating Security Mechanisms of Substation Automation Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ziyang Zhou; [2023]
    Nyckelord :Substation automation system; Threat modeling; Meta attack language; Stationsautomationssystem; Hotmodellering; Meta attack language;

    Sammanfattning : Substations are important components for transforming voltage and distributing power in electrical infrastructure. Modern substations are usually automated by substation automation systems, which offload the work of operators and reduce potential human error. LÄS MER

    Sammanfattning : Power systems in the industry today are adopting automated substations because of a growing trend of digitization. Substation automation has greatly reduced intervention from human as well as operation and maintenance costs. LÄS MER

  4. 3. Automatic post-fault analysis based on disturbance data stored in substation devices : Approach towards the preventive maintenance

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Riad Yalda; Miroslav Urosevic; [2019]
    Nyckelord :COMTRADE file; preventive maintenance; relay protection; automatic post-fault analysis; IEC 61850; wavelet transform.; COMTRADE filer; förebyggande underhåll; reläskydd; automatisk efterfelsanalys; IEC 61850; wavelettransform.;

    Sammanfattning : This report studies the possibilities of minimizing unplanned maintenance work and improving the availability of power supply by enabling preventive maintenance in power systems, without having to make additional investments in the existing systems. This was done using information from COMTRADE files (disturbance recording files) that are created in the event of a fault in the power system. LÄS MER

  5. 4. Digital secondary substations with auto-configuration of station monitoring through IEC 61850 and CIM

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Johan Wistedt; [2018]
    Nyckelord :IEC61850; RTU communication; HMI; grid protection; CIM; Network information system; intelligent electrical devices; secondary substation;

    Sammanfattning : This thesis explore the possibility to automate a process for configuration of secondary substations monitoring and control. By using a network information system (NIS), information of secondary substations can be extracted, such as feeder naming, primary equipment type, rating and model. LÄS MER
