… av mappen. För att få ett korrekt simulerat turbovarvtal under transienten var turbineffektivitetsmultiplikatorer introducerade. Med det var inte tillräckligt med tvåpunkts kalibrering av dessa och låta GT-Power interpolera emellan utan flera varvtal behövde kalibreras in för …
Utformning av bypassventil för reglering av turbininloppstryck
… skall undersökas är att reglera turbininloppstrycket med en bypassventil förbi turbinen, likt en extern wastegate. För att dimensionera denna bypassventil inför tillverkning samt för att undersöka bypassventilens inverkan på motorn utfördes simuleringar i GT-Power. Därefter …
The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the …
… Industrial Turbomachinery AB in Finspång. The company produce steam- and gas turbines and also provides service and maintenance. The purpose with this project has been to develop diagnostic methods that oversee the health of the control valves. By using the developed methods you …
… upgrading biogas. In this report there are short reviews of heat engines, gas turbines, fuel cells, PSA, scrubbers, cryogenics, internal methane enrichment, ecologic lung, sulphide- and water removal. Interesting and appropriate technologies for Gryaab might be high temperature …
… Inspection plugs can be found on virtually all aircraft engines and gas turbines. They are used during inspections with fiber optics done at regular intervals during engine operation. Since the inspection plugs are screwed in and out many times during the life of an engine, it …
Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
… and the consequent wind energy curtailment, additional cost efficient wind turbines could be established on the island. An alternative to EV load management is to increase grid capacity with a costly new sub-marine transmission cable. A Matlab model was used to estimate …
… effektvariationer vid varierande vindhastigheter. Aerodynamiska effekter hos turbinen ger problembilden en ytterligare dimension. De bakomliggande orsakerna beskrivs teoretiskt. Olika designmässiga val för att anpassa vindkraftverket till de dynamiska problemen tas även upp.

… is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools …
… is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects …
… about 30 GWh of electricity could be produced if the steam instead expands in turbines to reduce its pressure.
En förstudie i Leticia, Colombia
… turbin av modellen Darrieus installeras på en ponton vid samhället Milagrosa. Turbinen beräknas i dagsläget täcka det elbehov som finns i samhället. Dock kvarstår finansieringsfrågan.
… but the possibilities for solar cells are also an interesting solution. A wind turbine that will be able to produce the yearly amount of electric energy that the port needs, should have a rated power at around 20 kW and a tower height of at least 18 m.
… water current. The path of the movement is circular or a shape of an ”8”. The turbine under the wing is powered by the water flow which in turn leads to generation of electricity by the generator. The purpose of this thesis is to investigate the potential of using the Deep Green …
… power generation systems, based on the company’s own produced gas and steam turbines. The company has for years worked to establish a Lean-based thinking. The Procurement function, within the Supply Chain Management department (GP) is responsible for purchasing the supply system …
