1. 1. Study Of Universal Islanding Detection Techniques In Distributed Generation Systems

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Ochai Ochalla Danladi; [2023]
   Keywords : Distributed Generation; Islanding; Quality Factor; Resonance Frequency; Low Voltage; Medium Voltage; Electronic Power Converter; Inverter;

   Abstract : Energy security, global warming, and climate change have been a major source of global discussions and development. Likewise, the rising cost of electricity for consumers and exponential demand for energy are major factors driving the incremental growth and integration of sustainable forms of energy generation into power the system cycle.

3. 2. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

   University essay from Umeå universitet/Institutionen för fysik

   Author : Sara Holmér; [2021]
   Keywords : ;

   Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

4. 3. Managing cost accounting implementation through discourse: A single case study of PEC model implementation in Region Halland

   University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

   Author : Justus Kokki; Like Ma; [2020]
   Keywords : Hospitals; Accounting and organizational change; Process analysis; Time-driven activity-based costing; Implementation of new system;

   Abstract : This paper examines accounting and organizational change process and its institutional background by conducting a case study of the implementation process of a simplified Time-Driven Activity-Based Costing system in a Swedish Healthcare Region. Using a framework adapted from Zbaracki (1998), separating reality and rhetoric along a process-view, the paper examines how institutional forces enter the implementation process and how the arising tensions are managed along the process.

5. 4. Analysis of the energy consumption of the powertrain and the auxiliary systems for battery-electric trucks

   University essay from KTH/Fordonsdynamik

   Author : Guanqiao Song; [2020]
   Keywords : Battery-electric truck; Energy consumption analysis; Battery loss; PT1 battery model; Power Take Off; Sankey diagram; Direct-Current charging; Batterielektrisk lastbil; Energiförbrukningsanalys; Batteriförlust; PT1 batterimodell; Power Take Off; Sankey diagram; Direct-Current charging;

   Abstract : The electrification of the truck is crucial to meet the strategic vision of the European Union (EU) to contribute to net-zero greenhouse gas emissions for all sectors of the economy and society. The battery-electric truck is very efficient to reduce the emissions and has also a lower Total Cost of Ownership (TCO) compared to diesel trucks. READ MORE

6. 5. On the Influence of Scattering From a Power-pole on an Airport Radar

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