  1. 11. Real-time detection of stator resistance unbalances in three phase drives

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

    Author : Bhanu Pratap Singh; [2020]
    Keywords : DC voltage injection; Fault detection; Field-Oriented Control; Induction machine; Inter-Turn Short Circuit; Short circuit; Sequence; Stator resistance unbalance; Symmetrical components; likspänningsinjektion; feldetektering; fält orienterad reglering; induktionsmaskin; InterTurn Short Circuit; kortslut; sekvenser; statormotstånd obalans; symmetriska komponenter;

    Abstract : An estimated 30% of the faults in Induction Machine (IM) are related to its stator. These faults are mostly in the form of an Inter-Turn Short Circuit (ITSC) fault i.e., when two winding inside the stator of IM are shorted due to insulation failure. READ MORE

  2. 12. Condition monitoring of induction machines using a signal injection technique

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

    Author : Sathiya Lingam Senthil Kumar; [2020]
    Keywords : Condition monitoring; fault detection; fault diagnosis; stator winding fault; inter-turn fault.; Tillståndsövervakning; feldetektering; feldiagnos; statorlindningsfel; kortslutning mellan varv.;

    Abstract : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. READ MORE

  3. 13. Risk Management in Medical Devices: Hazard Identificationand Verification of Mitigation Controls

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Gislé Segura Roca; [2020]
    Keywords : ;

    Abstract : During this project, the risk management of a medical device under development that deals with drug administration has been done. The aim of the project is to evaluate if part of the device is safe according to the current regulations in Sweden. READ MORE

  4. 14. Developing for Resilience: Introducing a Chaos Engineering tool

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Ignacio Monge Solano; Enikő Matók; [2020]
    Keywords : chaos engineering; fault injection; resilience testing; distributed systems;

    Abstract : Software complexity continues to accelerate, as new tools, frameworks, and technologiesbecome available. This, in turn, increases its fragility and liability. Despite the amount ofinvestment to test and harden their systems, companies still pay the price of failure. READ MORE

  5. 15. Lineage-driven Fault Injection for Actor-based Programs

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

    Author : Yonas Ghidei; [2019]
    Keywords : ;

    Abstract : Lineage-driven fault injection (LDFI) is an approach for finding bugs or faults in distributed systems. Its current state-of-the-art implementation, Molly, takes programs written in the logic programming language Dedalus as its input. The problem is that Dedalus is a small and obscure language, used to serve as a proof of concept for Molly. READ MORE
