(Master thesis, 2020)As an alternative to fossil fuels and as a sustainable energy carrier, there are considerable interestsin investigating hydrogen. Hence, it seems significant to evaluate the behavior of hydrogen in refueling or storing. ... -
State Space Model Based PID Controller Tuning
(Master thesis, 2019)Advances in digital computing over the last years have resulted in new and powerful tools for obtaining process models. An example of such a tool is the dsr toolbox, which gives a state space model based on measured ... -
Dispersion of hydrogen in confined spaces
(Master thesis, 2019)Usage of hydrogen as fuel gives rise to possible accidental risks due to leakage and dispersion. The highest risk from hydrogen leak is the formation of a large volume of the hydrogen-air mixture, which could be ignited ... -
Improving the design of MV load-break switch contacts
(Master thesis, 2019)The breaking of currents either during maintenance, faults, or overload is common in load-break switches. Because switches are usually placed before critical installations it is important that their designs implementations ... -
Online monitoring and visualizing of a generator’s capability with Simulink
(Master thesis, 2019)The power systems today are becoming more larger, complex and are operating closer to their security and stability limits particularly due to an increase in load demands and number of environmental concerns. Voltage ... -
Model Fittng and State Estimation for Thermal Model of Synchronous Generator
(Master thesis, 2019)The power factor of a synchronous generator, in a European hydropower generation, is constrained to [0.85, 0.95], and for Norway, it is generally below 0.86. A higher power factor means more exploited power (active power), ... -
Process simulation of CO2 absorption at TCM Mongstad
(Master thesis, 2019)Developing robust and predictable process simulation tools for CO2 capture is important for improving carbon capture technology and reduce man made CO2 emissions. In this thesis, five different scenarios of experimental ... -
