Kan Orust bli självförsörjande på förnybar el?

Examensarbete, avancerad nivå · Uppsala universitet

… of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid. The conclusion is that the …

Ny stamstation i Yttermalung för anslutning av vindkraft

Nätstudie av olika utföranden i normal- och reservdrift

Examensarbete, avancerad nivå · Uppsala universitet

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 …

Effekten av höghöjdsvistelse på anaerob arbetsförmåga

Kandidatuppsats · Mittuniversitetet

… expeditionen genomförde försökspersonerna ett anaerobt wingatetest där peak power, average power, minimum power and power drop uppmättes. Resultatet visade en signifikant sänkning av average power efter den genomförda expeditionen på hög höjd, med ett medelvärde på 8.44 ± 0,84 …

Peltierelement - spillvärme till el

Peltier element - waste heat into electricity

Examensarbete, grundnivå · Uppsala universitet

… used in a comparison study. The comparison was mainly done to know how much power could be obtained from each element. Even, a circuit with a step-up function has been created to give a higher output voltage than the peltier element itself. The result of the experiments was a …

Inventering av värmelager för kraftvärmesystem

Kandidatuppsats · Linköpings universitet

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 …

Implementering av en PSS i Trängslets kraftstation

Examensarbete, avancerad nivå · Uppsala universitet

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power …
