1. 21. Short-circuit Contributions from Fully-rated Converter Wind Turbines : Modeling and simulation of steady-state short-circuit contributions from FRC wind turbines in offshore wind power plants

   University essay from KTH/Elektriska energisystem

   Author : Joakim Ahnlund; [2014]
   Keywords : ;

   Abstract : In recent years there has been an increase in wind power plants installed out at sea. The generated power of wind turbine generators (WTGs) are collected through numerous subsea cables into a single hub, the offshore platform. Subsequently, this platform is interconnected with the onshore main grid through a further stretch of cable. READ MORE

   Abstract : The rapid growth of the electric power system has in recent decades resulted in an increase of the number of transmission lines and total power outage in Norway. The challenge of a fast growing electrical grid has also resulted in huge increases of overhead lines and their total length. READ MORE

4. 23. Thermodynamic modeling of the stacking fault energy in austenitic stainless steels

   University essay from KTH/Termodynamisk modellering

   Author : Malin Olsson; [2014]
   Keywords : Austenitic stainless steel; Stacking fault energy; Thermodynamic modeling; Thermo-Calc;

   Abstract : The stacking fault energy (SFE) of seven austenitic stainless steels with the compositions x(Cr)=20 at%, 8≤x(Ni)≤20 at% and 0≤x(Mn)≤8 at% have been calculated at room temperature using the thermodynamics-based Olson and Cohen modeling approach [1]. Modeling has been performed using the TCFE7 database together with the Thermo-Calc 3. READ MORE

5. 24. Study on Fault Detection andLocalization for Wave length Division Multiplexing Passive Optical Network

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Sunil Poudel; [2013]
   Keywords : Wavelength division multiplexing passive optical network WDM-PON ; open access;

   Abstract : Wavelength division multiplexing passive optical network (WDM-PON) can meet growing bandwidth demand in access network by providing high bandwidth to the end users. Failure in the access network is becoming critical as a large volume of traffic might be affected. READ MORE

6. 25. Grid Code Compliance – Wind farm HVDC connection

   University essay from Elektricitetslära

   Author : Martin Västermark; [2013]
   Keywords : Grid Codes; HVDC; Offshore Wind; East Anglia; PSS E;

   Abstract : A rapid development of offshore wind power is planned in GB as a part to fulfil the EU2020 targets. 25 GW wind power capacity has been awarded to developers in nine different offshore zones outside the coast of UK. READ MORE
