… system for extracting electrical energy from ocean waves with a Wave Energy Converter (WEC). The components is bought from subcontractors and then assembled into wave energy converters, buoys and marine substations by Seabased. In the future Seabased will produce more of the …
En statisk och dynamisk modelldesign över VSC-HVDC för implementering i ARISTO
… dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well …
… to, various electrical devices as, flow meters, temperature sensors, frequency converter and more. In order to control and manage the various electrical devices or elements, the USB-6009 (DAQ) is being used, which is programmed through the LabVIEW, to control and monitor the …
… system. Grid-connected systems are not profitable because of the cost of power converters, and also because of prohibition of net metering in Sweden. Solar water heaters are not profitable because there is currently no subsidy available.
… and development havebeen done for several years. Severaltypes of wave energy converters (WEC)have been created. The project facesmany challenges, but as always itultimately boils down to cost versusefficiency and energy conversion. Oneway to reduce production costs is toreduce …
Förnyelsebar energi är viktigt för att minska människans negativa miljöpåverkan. Ett steg i processen är optimeringav transmissionsnätet och investering i fler förnyelsebara energikällor, till exempel vinkraftparker.Vinkraftparker med enbart likströmsöverföring har lägre …
En analys av hur grunden för frihetsberövandet påverkar ersättningens bestämmande
The purpose of this study is to investigate a group of female converters and their subsequent experiences when transitioning to islam by bearing hijab. The study analyzes how this religious conversion has shaped and influenced the identity of mentioned women, as well as their …
En studie om fem kvinnors konvertering till islam
The purpose of this study is to investigate a group of female converters and their subsequent experiences when transitioning to islam by bearing hijab. The study analyzes how this religious conversion has shaped and influenced the identity of mentioned women, as well as their …
Att ta fram ett konstruktionsunderlag för ett småskaligt vindkraftverk som vanlig användare är en tidskrävande process och professionell hjälp kan behövas. Ett verktyg som automatiskt genererar ett sådant underlag skulle medföra stora tidsbesparingar samtidigt som det går att …
… air ” 18.9 kWh/m2/yearComputer units ” 7.8 kWh/m2/yearFrequency converters ? 4.4 kWh/m2/year Waste heat from industrial processes, primarily from the production hall leads to high cooling demand to maintain good thermal comfort. Limitations in operation control of the buildings …
… and resistance. The final circuit was based on the chosen analog to digital-converter, Maxim integrated´s Max134, which is the main component of the circuit for this instrument. A circuit diagram and PCB layout were made. The result of this project is a constructed DMM board …
… of uninterruptible power for motor operation is facilitated using a frequency converter. Direct current operated frequency converters can be applied directly to the power reserve which removes the need for additional power-converting. Batteries have long constituted the power …
… scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as …
Energi är en resurs som måste användas effektiv för att undvika onödig negativ miljöpåverkan och utgifter. Återmatning från nedåtgående malmtåg till uppåtgående malmtåg leder till en effektivisering i energiutnyttjande. Beräkningen av den återmatade energin utgår ifrån tågets …
… of two different technologies(Doubly fed induction generators and full power converters) can meet therequirements and technical proposals have been given on how to be able to meetcompliance with the new grid codes. The Requirements for Generators contains many non-exhaustive and …
