Utredning av åtgärder för ventilation, värme och kyla
… for the different areas have been divided into two different parts, electricity- and heat consumption. Electricity consumption is roughly 500 MWh per year and the heat consumption is around 1020 MWh per year. This is only the consumption of the areas that have been investigated …
… purpose has been to develop a design tool to be used for development of new electric motors for Atlas Copcos electric nutrunners. The focus of the thesis has been to increase productivity by decreasing the power losses in an electric tool. The productivity is defined as the …
This thesis is focused on identifying and documenting all electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief technical description and information of the systems around the reactors. Furthermore there will …
… degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for …
… evaluate the possibilities and difficulties associated with the design of an electric power assist servo for all terrain vehicles (ATVs). The project has been carried out in collaboration with Nira Control AB. Nira designs and manufactures electric and electro mechanic products …
… of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer. The company Minesto has developed a technology that is called Deep Green …
The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power …
… play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät (SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more …
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical …
Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
… in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was …
… perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data …
The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a …
… efforts shall be rewarded. The nuclear power energy importance for the Swedish electricity power balance hasbeen discussed. The conclusion is that customers, electricity generators and thepublic benefits from reliable and secure nuclear power management.
… will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear …
… it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied: ? Certificate system. A certificate …
