Optimerad styrning av kondensatorbatterier - Ny möjlighet att minska förluster med elektronisk brytteknik

Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.

Fallet SAS : En studie i hur medial diskurs reproducerar maktförhållanden på arbetsmarknaden

Aim: The purpose of this study is to explore how the media through a certain discourse constructs a view of the labor market and the power relations between companies, unions and employees. The goal is to explore this through studying the media coverage of SAS? financial situation between September-December 2012 and our research question is the following: What view of the labor market and its power relations was constructed and reproduced by Swedish newspapers through their portrayal of SAS during September-December 2012?Method: This study analyses the findings with the help of questions based on theories of social constructivism, discourse, agenda-setting and power. A content and discourse analysis was compiled of 360 articles from five Swedish newspapers that addressed SAS and their situation from September-December 2012. The results of these analyses were further processed using power analysis and John Gaventa?s power cube.Results: In this study we conclude that the medial discourse constructs identities of the different actors and affect power relations between them, in favor of the company.

Socialarbetare : professionell medmänniska eller byråkrat?

The purpose of this study was to examine how social work professionals view their professional role and how they think about the concept of social work. I also wanted to investigate what they believe characterize a professional social work. For the purposes of this study, I chose a qualitative approach in which I interviewed five people linked to the social work. The theories which I have assumed in the analysis of the results are power theory, organization theory and professional theory. The results of this study show that the respondents believe that a professional social work is performed by someone who has training and experience in the field.

Den gröna konsumentmakten - medborgarens ekologiska insats

The aim of this thesis is to form a theory of the green consumer power and to distinguish whether this phenomenon could indicate a movement toward the ecological citizenship. To do so, scientific theories regarding the responsibility of companies have been used, as well as the public choice theory, to link individuals as citizens to individuals as consumers. The motives of corporate environmental responsibility, along with consumers ability to bring pressure in different dimensions, are later drawn on as indicators applied to empirical information. The largest producer of ecological products in Sweden, Arla Foods, is employed as case study to explore if the green consumer power can and does exist. The ecological citizenship uses the ecological footprint, to define in what ways we can minimize our part of environmental degradation.The study seems to strengthen the theory, consumers do have a power to make companies go green and they tend to use it increasingly.

Mätning i nätstationer - nyttor och problem

The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Validering av vattenkraftmodeller i ARISTO

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

Rytmikaren och båtbyggaren - En studie om den tysta kunskapen inom rytmiken

Title: Eurythmics, and building boats -A study in tacit knowledge.The education of eurhythmics at Malmö Academy of Music, is a program where a major part of the tutoring is oral; very little written information about the method is used. This essay will examine the forms in which the current knowledge base exists, as well as the methods in which this information is transmitted from teacher to student, and in which form the knowledge about the method of eurhythmics is existing. The tools for analysis are the theories on tacit knowledge. Interviews and written surveys are used as qualitative research methods. The content of these interviews and surveys are presented in the results chapter.

Investeringsbeslut för småskalig vindkraft : en fallstudie

Wind power is one of the sources of renewable energy which has to be developed further in order to lessen our dependence on non renewable sources of energy. It's mainly oil and coal which have to be replaced by green energy. Wind power is already established in many countries, for example Germany, The United States of America and Denmark but it has to be continually developed and expanded to meet the needs of the growing energy consumption in the world. During the last few years many types of small wind turbines have appeared on the market. These small wind turbines are an alternative to the big wind turbines or power generators which demand huge sums of investment money.A new target group can now buy the small wind turbines in order to cover their own usage of electricity.

Analys av mätdata från nätstationer

Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.

"Allt jag gör lär jag mig ju av". En studie om kunskapskrav och kunnande i anslutning till audionomstudenters praktiska utbildning

The audiologists´ knowledge-domain is generally described as a unique combination of medical, technical, social and behavioural sciences. It gives prominence to the importance of an adequate education relating to the knowledge-demands the students´encounter during their trainee-period. However, an important question is if the educational content corresponds to the knowledge-demands during the training? Aim: This study aimed to identify the knowledge-demands of students during their trainee-period. Furthermore, to identify how the students´ actual knowledge was related to the encountered knowledge-demands.

Fordrande ord : en kritisk diskursanalys av konsertinstitutioners informativa texter inför konserter

The aim of this master?s thesis is to explore concert institutions? informative texts prior to upcoming concerts ? texts in promotional materials and descriptive texts in programme papers. The thesis is carried out from a critical discourse analytical perspective. The discourse analysis is focusing on finding the texts? messages and it asks the question: To whom are these texts addressed? Theoretical support is mainly taken from Foucault?s theory about the relation between Power and knowledge.

Från snopp till kropp : En c-uppsats utformad inom sex och samlevnad

 Detta är endast en del av ett stort arbete, på grund av omständigheterna (till exempel möjligheten att publicera en power point) har vi varit tvungna att begränsa vår publikation till lärarhandledningen. Det finns också en elevutgåva, power point-presentation samt ett prov som inte publiceras. För att ta del av dessa krävs möjlighet att komma åt Biologi C för lärares kurswebb Vt-2008 på Södertörns högskolas intranät. .

"I go to Elland Road sometimes. Would you bomb me?" : en genealogisk närläsning av villkoren för överlevnad och subjektivitet i Sarah Kanes Blasted

Sarah Kane?s first play Blasted (1995) has often been read in a normative and biographical way by critics, authors and previous researchers. This essay makes a supplementary close reading of Blasted from gender and genealogical perspectives and utilizes theoretical works by Judith Butler, Luce Irigaray and Michel Foucault. My study makes clear that the characters different positions in language and talk create and maintain a power imbalance between them. Efforts to change and develop one?s individual position in language and talk are being made throughout the play since it is the only way to bring about a change in the social power structure.

Global uppvärmning : gymnasieelevers oro och kunskap

Global warming is generally recognized as one of the major environmental challenges we have to face in the near future. The students in school today are the ones that will have to deal with the consequences of it tomorrow. That is why education about it is so important. Previous research shows that students believe that environmental issues in general are important problems to be solved. I this study I tested students in grade twelve, in four different schools in order to find out what their level of knowledge about global warming is, how worried they are about it and if there are any correlation between their knowledge and their level of worry.

Svininfluensan : en kritisk diskursanalys av medias rapportering

Media has the power to influences society. Some call them the third power of a state. Through amongst others, the agenda setting theory and the framing theory, this report seeks to understand how media describes the swine influenza and how it uses its power to influence people to vaccinate. As this report will show, there is no doubt that media has had an impact on the Swedish population of which 60 per cent followed through with the vaccination. Media used an information discourse and attempted to present its articles in an impartial manner and used governmental authorities and experts to support its arguments.
