Ny stamstation i Yttermalung för anslutning av vindkraft : Nätstudie av olika utföranden i normal- och reservdrift

Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.

Utvärdering av viktmåttbaserad reglering av lokal- och regionnätens resursbehov

The Energy Market Inspectorate is implementing a new tariff regulation in Sweden. A small part of the new regulation concerns effectible operation costs and originally they where intended to be calculated using a modification of equivalent comparison standards, in Swedish Ekm. This thesis is intended to analyze if Fortums grid in Stockholm could be described correctly, using equivalent comparison standards. In Ekm every part of the distribution grid is designated a weighting in relation to 1 km 0.4kV over head line. These Ekm-measurements are intended to simplify comparison between different grid areas with different structure and geographical conditions.

Kollektivtrafikanalys av Frihamnen Göteborg. En studie av olika utbyggnadsscenarier och dess transportbehov vid en färdig utbyggnad av Frihamnen år 2040

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Sveriges inställning till EMU : underkastelse av kollektivet kontra nationell obundenhet

After Sweden became a member of the European Union, EU, the debate regarding the Swedish participation in the EU?s currency co-operation, the European Monetary Union, EMU, has been intense. One of the biggest issues has been how our national economic politics will work within such a monetary union. What instrument will remain for the national economic politics within the EMU are highly uncertain. The question whether we will be able to affect our own economy or not has long been the essence in the Swedish debate.

Elmätarens roll i framtidens elnät : Ett samarbete med Sweco Energuide AB och Mälarenergi Elnät AB

The initial aim of the roll out of smart electricity meters in Sweden was to allow remote readings of the households? monthly electricity consumption for billing purposes. Since then the transition towards a smart grid has become a more prioritized matter. In the roll out of next generation smart meters more attention is therefore given to how the Distribution System Operator (DSO) can benefit from the meter through different smart grid applications. This study uses a qualitative research method to identify three general fields of application and 15 specific concepts corresponding to ways in which the DSO can create added value from the information provided by the smart meter.

"Man får liksom inte bli slav under nationella prov" : en undersökning om lärares reflektioner kring de nationella proven i årskurs 3

Since the beginning of 1940 there have been externally developed tests in Sweden. Their appearances have changed over the years together with the cognitive approach. Nowadays, this kind of tests is going by the name of the national tests, which was introduced in the year of 1994. When the Swedish National Agency for Education received the assignment to develop new purposes and national tests to the third grade students, debate took a bounce. The matter was well discussed; national tests in third grade or not?The national tests thus far carried out four rounds in the third grade and the purpose of my study was to find out how teachers are reasoning about the tests.

Textile Grid

Resultatet är fem material som viksoch formas efter sin egen konstruktion..

Initiativ till förändring av det vetenskapliga publiceringssystemet : med fokus på högskolebiblioteket

This masters thesis shows that the changes in the scientific publishing system have affected the academic libraries. Both technological change and the increased prices on scientific journals have forced academic libraries to take action. Some Swedish academic libraries have started publishing the university s own research material. The issue has in many cases been treated more as a library concern, than as a concern for the university as a whole. Neither has there been a national coordination of these matters in Sweden.

Beslut om betydande miljöpåverkan för järnvägsprojekt : beslutsmotiveringar, åtgärder och regionala skillnader

This thesis examines the reasons to why railway projects conducted by Banverket (Swedish National Rail Administration) could be expected to cause significant effects on the environment, on which grounds the County Administrative Board and Swedish National Rail Administration base their decisions/assumptions and highlight regional differences between the different Swedish national rail administrations regions. Total 24 railway projects, conducted or being conducted, during the time period 2001 - January 2010 have been analyzed and studied. These projects represent eight different measures/activities which are dispersed throughout all five of the Swedish National Rail Administration´s different regions. Swedish legislations demands that the planner of a new railway project shall first conduct a pre-study and then conduct a public consultation which provides the participants an opportunity to provide input. The County Administrative Board shall then decide if the project could cause significant effects on the environment.

Om att rättigheten att behandlas lika ska vara lika på olika platser - En beskrivning av svensk diskrimineringslag i relation till EU

This bachelor thesis is studying the development of Swedish law in relation with EU-law. There are two different points of view expressed in the theories of Europeanization. One that means EU makes a big influence on national policy, one that says path-dependency will make the national policies differ. The case used in the study is discrimination on the ground of disability as regards employment. The aim of this thesis is, through a case study, to analyze the relation between Swedish and European law and by that shed some light on the matter of Europeanization..

VSM och 16 förluster

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Idealkonstruerade offer och gärningsmän i en verklig värld : En analys av fyra omskrivna sexualbrottsfall i svensk rikstäckande dagspress under 2000-talet med fokus på genus, etnicitet och social bakgrund

We have chosen to analyze how four well known sex crimes were presented in the Swedish national daily newspapers in the 2000s. We chose this topic because sex crimes are considered one of the most terrible crimes. Sex crimes involve the media and upset the society. Our purpose was to analyze if we could identify stereotypes and prejudices about sex crimes in the press reports.The four sex crimes were: Rissne case in 2000, Tumba case in 2003, Hagamannen case in 2006 and the Stureplan case in 2007. We have read all the news stories from the Swedish national daily newspapers Svenska dagbladet and Expressen about our four cases.

Förhandlingslösning som alternativ till fortsatt militär kamp : en studie av två irreguljära parters val

The Swedish Armed Forces tend to ask themselves if it is sufficiently multinational interoperablefor participation in international operations. An equally valid question today should be whether theSwedish Armed Forces are sufficiently nationally / internally interoperable, between their branchesof service, to be able to conduct independent operations based on the joint warfare theory.The lack of ability to joint warfare in the armed forces in general and the Swedish Armed Forcesspecially constitutes the essay´s fundamental problem. By using Codners and Sjöbloms custominteroperability theory, the Swedish Armed Forces documents were analyzed to highlight anyweaknesses related to joint warfare and national interoperability between Ground and Air Forces.The survey shows weaknesses linked to the custom theory and Swedish Armed Forces governingdocuments. The ability of a national interoperability is limited between Ground and Air Forcestoday, mostly because of weaknesses in the Swedish Armed Forces strategic concept which doesnot describe the importance of joint warfare at all levels sufficiently. This leads to deficienciesreflected in doctrines, regulations, technology, techniques and exercises.

Förflutna landskap idag : en diskussion om begreppet landskap

The first part of this essay focuses on how we relate to the landscape at the international and the national level today. The landscape convention is presented and compared to actual current Swedish policies. Different definitions of landscape are discussed. The second part renders the landscape in different archaeological contexts. The central theme is the attempt to investigate if and how we can approach prehistoric man by looking at the landscape as a socially constructed concept.
