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.

 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. .

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.

The study focus on the development of the bilateral relationship between India and the United States and the Next Step in Strategic Partnership (NSSP) from 2004 and the change in U.S. approach to India's neuclear program. With the rise of China to potential great power status I argue that the cooporation between the two is an act to balance the Chinese influence and to prevent future rivalry and a Chinese dominance of the East Asia. For the study I have used concepts and theorys from the realist tradition, in particular theorys of Balance of power and alliance forming..

We have studied the process of recruiting young people to the white power movement. With the help of theoretical concepts as Outsiders and Stigma, we have elaborated the purpose of the study. The focus of the study lays in finding out which elements contributes to adolescence seeking membership in white power, and furthermore what white power organizations offers young people, to attract them to recruitment. We also want to find out if it possibly lays a desire for communion, behind adolescences decision to join these movements, and also how the communion manitains within the group? To expand our knowledge in the field of White Power, we have taken note of a body of literature that deals with the current topic, and previous research that treats questions about subculture, community and recruitment.

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.

The relationship to professionals has proved to be a helping factor for personswith severe mental illness, but it is also a relationship characterised by anunbalanced power relation. The aim of this study was to compile and analyze theknowledge of what persons with severe mental illness themselves consider to behelping in the relationship to professionals, and to specifically analyse this from apower perspective. The analysis was conducted using Foucault?s ideas of powerand knowledge, and an empowerment perspective. The method used was anarrative review.

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

John A. Warden III is one the most mentioned air power theoretic of his time.He has written a number of theories concerning air power and the best way to use this to win wars.The author of this paper gives a short resume of what he consider are the central thoughts in John Warden´s theories. These thoughts result in four factors; Enemy as a system, centre of gravity, parallel attack/concentration and finally air superiority. These factors are then being used to inves-tigate if NATO used Wardens theories during the Kosovo war in 1999.The reason for the author to choose the Kosovo war specifically is due to the fact that NATO during the war only used air power as an instrument to get Serbia´s president Milosevic to the negotiation table but also the fact that this would turn out to be quite a challenge for NATO.The conclusion is that out of the four factors only one is traceable throughout the entire operation, and that is air superiority. Regarding the other three factors they can only be found in parts of the operation..

This essay is about power, democracy, solidarity and equality in preschool. I examine three different situations to determine if I could have acted more sensibly in my interactions with the children. I portray: a ?children?s choice meeting? where children select an activity, a so-called emotional gathering and a dialogue at the lunch table about a popular movie that we plan to watch together afterwards. The purpose of this essay is to examine which norms and values form the basis of my actions, and if so, how these lead me to use my power to shape the children.I have chosen to use hermeneutic and norm-critical perspectives where I investigate and examine my norms and values and how I react and act, both consciously and unconsciously.

The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types. The data was collected from an electric power line going from the north to the south of Sweden. The mean value of the clearcutted area around the power line was 120 meters. The main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set. The main parameter studied was the damage frequency at the edge of the forest compared to the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated. The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species. A marked difference was observed between tree species and damage frequency.

The wind power increase of Gotland as well as other parts of Sweden during the last ten year period has meant that this renewable energy source has increased its share over other fossil sources. The year of 2011 became the first when the wind power produced more energy than an average nuclear reactor. Now that wind power is in an expansive phase, the land issue will be of great interest. Land with good wind resources will be of interest to wind energy developers. The problems that this essay is based on are; how can landowners altering the economic conditions at a wind power establishment? What opportunities and obstacles exist for landowners who choose to set up wind power on their land? The purpose of this essay is to highlight the economic conditions that exist for landowners for the establishment of wind farms, with regard to compensation for the leasing and return on invested capital.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

This essay deals with the paradox of why the immigrants in Sweden, despite their considerable size of 12 % of the population and common interest and living opportunities, haven?t mobilized politically in any significant way. The aim with this essay is to reach a theoretical understanding of why this paradox exist. By the use of a critical case and a theoretical model, based on theories of collective action, the conclusion of this essay is that, despite the fact that the immigrants have a common interest and an organizational structure, the immigrants in Sweden has not mobilized politically in any significant way. The main reason for this is that they have a weak common identity and they don?t have the structural opportunities to act..
