  1. 1. Substation digitalization and fault isolation : A study of the influence of degree of digitalization to regulatory indicators in the power grid

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

    Author : Ili Atalla; [2023]
    Keywords : ;

    Abstract : With changes in the energy sector, more demand is set on the power grid as electricity consumption is seen to increase and more decentralized renewable energy production is connecting to the grid. Svenska Kraftnät, electric system transmission operator in Sweden, describes the importance a more secure operation of the power system. READ MORE

  2. 2. Statistical analysis of corrective and preventive maintenance in medical equipment

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Linn von Schewelov; [2022]
    Keywords : Correlation Analysis; Regression Analysis; Survival Analysis; Medical equipment; Corrective Maintenance; Preventive Maintenance; Least squares; Cox Proportional Hazards model;

    Abstract :  Maintenance of medical equipment plays an important role in ensuring the healthcare quality so that the care can be conducted with minimal risk. Preventive maintenance is performed to maintain the equipment in satisfactory operating condition, while corrective maintenance is made when there is an unpredicted maintenance requirement.

  3. 3. Improving maintenance scheduling with condition monitoring on the electric distribution grid : An economic analysis comparing corrective and predictive maintenance

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

    Author : Hugo Vincenti; [2022]
    Keywords : Condition-based maintenance; predictive maintenance; health index; failure rate; maintenance scheduling; sensors; economic analysis; simulation; Tillståndsbaserat underhåll; förebyggande underhåll; hälsoindex; felfrekvens; underhållsplanering; sensorer; ekonomisk analys; simulering.;

    Abstract : A growing use of sensors on the electric grid has opened the door to new methods of asset management: Distribution System Operators are now looking into conditionbased maintenance, as opposed to the traditional corrective or time-based methods. As an emerging field, the methodology must be constructed from the ground, with the little data available. READ MORE

  4. 4. Natural Language Processing for Swedish Nuclear Power Plants : A study of the challenges of applying Natural language processing in Operations and Maintenance and how BERT can be used in this industry

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Felix Kåhrström; [2022]
    Keywords : NLP; Natural language processing; Machine learning; BERT; Nuclear power plant;

    Abstract : In this study, the current use of natural language processing in Swedish and international nuclear power plants has been investigated through semi-structured interviews. Furthermore, natural language processing techniques have been studied to find out how text data can be analyzed and utilized to aid operations and maintenance in the Swedish nuclear power plant industry.

  5. 5. Periodical Maintenance Modelling and Optimisation Assuming Imperfect Preventive Maintenance and Perfect Corrective Maintenance

    University essay from KTH/Optimeringslära och systemteori

    Author : Madeleine Engvall Birr; Lisette Lansryd; [2021]
    Keywords : Master Thesis; Maintenance Management; Maintenance Modelling; Imperfect PM; Perfect CM; Periodic Policy; Genetic Algorithms; Age Reduction; Masterexamensarbete; Underhållsarbete; Underhållsmodellering; Ofullständiga FU; Perfekta AU; Periodisk Planläggning; Genetiska Algoritmer; Åldersreduktion;

    Abstract : In this paper, a periodic maintenance model is formulated assumingcontinuous monitoring, imperfect preventive maintenance (PM) and perfect correctivemaintenance (CM) using three decision variables, (I, N, Z). The model is derived in aninfinite horizon context where the mean cost per unit time is modelled. READ MORE
