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 ... -
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 ... -
Consumer Flexibility as a Resource for Efficient Utilization of Existing Power Grids
(Master thesis, 2021)With the aid of demand response, this paper examines the impact of heating, cooling, ventilation, electrical vehicles and solar panels/photovoltaic (PVs) of a commercial building on the distribution grid. It also categorizes ... -
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 ... -
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 ... -
Modeling the Excitation Control System of a Hydropower Controller in Modelica
(Master thesis, 2021)Hydropower technologies are crucial to provide flexibility, reliability, and stability to the grid compared to other renewable energy technologies. Therefore, the number of hydropower plants, mainly the small-scale plants, ... -
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 ... -
Control Relevant Model of Synchronous Generator Attached to Turbine and Grid
(Master thesis, 2021)A synchronous generator is one of the important units in the hydropower plant that plays a key role in the production of electricity. Much effort has been done for designing more accurate models of synchronous machines ... -
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 ... -
Non-intrusive ultrasonic sound detection of internal arc fault in medium voltage switchgear
(Master thesis, 2021)Arc fault protection is becoming ever more critical for all power systems to maintain the safety of personnel and reduce damage to expensive equipment. An internal arc fault is an unintentional event within an enclosed ... -
Thermal capacity and loading assessment for 24 kV XLPE-insulated cables in air
(Master thesis, 2021)Charging large battery packs requires high currents, especially for short-term charging of electric vehicles. The ohmic losses heats up power cables and is the limiting factor for the current capacity. However, the power ... -
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 ... -
Testing All-in-one-protection for any power distribution application using real time simulation
(Master thesis, 2021)The work was done as part of Master thesis at the Department of Electrical Engineering at USN, Porsgrunn, Norway. -
Thermal overloading of MV metal enclosed switchgear
(Master thesis, 2022)Going electric is an important step toward a more environmentally friendly world by reducing greenhouse gases. Some electrical devices might be able to withstand a short-term overloading, which for example can be used for ... -
System Grounding of 132kV Networks
(Master thesis, 2022)As the use of other renewable energy sources such as wind increases to reduce the carbon dioxide emission into the environment, the transmission and distribution network increase, and the Local Vestfold and telemark region ... -
Optimal Scheduling for Mobile Battery Charging Systems
(Master thesis, 2022)A pilot project in Norway is currently being examined to give electric energy to construction sites in places where connection to the power grid is not available. This thesis proposes a generic mobile battery charging ... -
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 ... -
