Development of a HIL system for simulating FMUs
(Master thesis, 2023)Several years ago, USN purchased a servo test stand for education purposes, to demonstrate small-scale load handling, consisting of two induction machines connected to each other, and controlled by its own driver. The servo ... -
Development of an open control interface for a servo machine test stand
(Master thesis, 2022)For noen år siden gikk USN til anskaffelse av et servomaskin testoppsett, bestående av en servomaskin med tilhørende drive koblet til en frekvensstyrt asynkronmaskin. Oppsettet er brukt til småskala lasthåndteringsdemonstrasjoner ... -
Digital Twin for Industrial Induction Heating Equipment
(Master thesis, 2021)EFD Induction want to look at the possibility of developing a digital twin for their induction heating equipment. A digital twin has a variety of usages, such as monitoring, predictive maintenance, and testing what-if ... -
Direct methods for transient stability analysis and contingency screening in power systems
(Master thesis, 2023)This master’s thesis addresses the challenges associated with power interruption and unstable operation in power systems. It highlights the potential for enhancing transient stability analysis through the utilization of ... -
Emission Free Construction Site-Thermal Overloading of the Charging System
(Master thesis, 2022)In Norway, many municipalities set the target toward the emission-free construction site. Skagerak Energi also took a step toward this emission-free construction site by charging the construction machinery with the help ... -
Evaluation of battery storage in combination with hydro-power systems
(Master thesis, 2021)As the power grid moves away from larger rotating masses, thereby decreasing the inertia and making the grid more sensitive to production changes, it becomes more and more important that new and improved power reserves ... -
Frequency in power converter dominated system
(Master thesis, 2021)The penetration of power electronic converter into the power grid is increasing at a noticeable rate, which causes the number of conventional synchronous generators (SG) to decrease. As a result, the power electronic ... -
Frequency stability in integrated synchronous power systems
(Master thesis, 2018)In the later years, the frequency quality in the Nordic synchronous system has been reduced significantly. In order to restore the frequency quality, new requirements for the primary frequency control (FCR) is under ... -
Generating and capturing IEC 61850-9-2 sampled value measurement for data analysis
(Master thesis, 2021)The generation and transmission of sampled value IEC 61850-9-2 signal according to the abstract specifications of IEC 61850-7-2 subsection is never overrated. The communication pattern initiated from the instrument devices ... -
Grid stabilization through load side mechanisms
(Master thesis, 2023)The composition of the power systems is subject to change, both on the generation and load side. On the generation side there is an increase in renewable energy sources that are connected to the power system with power ... -
Heat transfer mechanisms in MV load break switches
(Master thesis, 2017)This report is part of an ongoing research project between University college of Southeast Norway and ABB Power product division. This report focuses on the heat transfer from two load break switch (LBS), normally used in ... -
Heating of buildings with focus on measurement and control
(Master thesis, 2015-09-25)In Norway 60% of all energy is commonly used for heating, during cold winters this number is seen to rise even higher. Any reduction in the standby power used for heating will result in large power savings. In this thesis ... -
Hybrid Machine Learning and Mechanistic Thermal Model of Synchronous Generator
(Master thesis, 2021)Overheating of synchronous generators may result in shortened generator lifespan, thus strict constraints are imposed on their operation. A dynamic model of the generator temperature may leave good monitoring of the generator ... -
Hybrid Machine Learning and Mechanistic Thermal Model of Synchronous Generator
(Master thesis, 2020)Strict constraints are imposed on the power factor in the operation of the synchronous machines for electricity production, which are in place to protect the synchronous generators from overheating due to the increase in ... -
Hydropower unit – An analysis of operational efficiencies and energy losses
(Master thesis, 2021)The beginning of the “green shift” has already started in the Nordic power grid. In this context, it means extensive use of intermittent energy sources like wind and solar power. The intermittent sources impact the operational ... -
Improving snow melt systems energy performance
(Master thesis, 2015-10-09)The Object of this report is the district heating snow melt system installed in Notodden, Norway.The heat is generated by 4.7MW woodchip burner, together with oil and electrical boilers to cover peak loads.The heat is ... -
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 ... -
Influence of thermal radiation in MV switchgear
(Master thesis, 2019)When developing MV switchgear units it is important that the finalized product is within IEC maximum temperature rise limit. When a switchgear unit is developed it is continuously tested until it meets the requirements, ... -
Model based control of run-of-river power plant Grønvollfoss
(Master thesis, 2015-10-09)Water level in the pondage is an important parameter for a run-of-river hydraulic power plant. Keeping a reasonably high waterfall will help to reduce the total cost of power generation. The aim of the work for this thesis ... -
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), ...
