  1. 1. FEATURE EXTRACTION AND CLASSIFICATION OF TRANSIENT FAULT RECORDS

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Emanuel Bjurhager; [2023]
    Keywords : ;

    Abstract : As the power distribution system grows and more sensors are added, more data is created every day. This data can be crucial for finding faults, but there is now so much data that it ends up being unused. This presents a valuable opportunity to gain crucial insights into the continuously expanding and increasingly complex power distribution system. READ MORE

  3. 2. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Farsad Mansori; [2022]
    Keywords : Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

    Abstract : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. READ MORE

  4. 3. CHILLER DIAGNOSTICS Machine learning approach Carrier

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Vilius Koegst; Tatiana Orlova; [2022]
    Keywords : Technology and Engineering;

    Abstract : Chillers are large and complex machines that are used for temperature regulation in large buildings and plants. An undetected fault in the machine can lead to extended downtime and cause both great financial losses and increased environmental impact. READ MORE

  5. 4. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Isabelle Löfgren; [2022]
    Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

  6. 5. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Soham SinhaRoy; [2022]
    Keywords : Symmetrical monopole; HVDC LCC and VSC; CTL; MMC; Converter reactor; DC smoothing reactor; DC pole-to-pole fault; Peak factor; SCC; SCR; PSCAD EMTDC;

    Abstract : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. READ MORE
