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), ... -
Modeling of a Fault Ride Through in Transmission System with Distributed Hydropower Production
(Master thesis, 2018)As part of the development plan for the European Transmission Network, the European Network of Transmission System Operator (ENTSO-E) proposed the creation of a Network code dealing the requirements for the grid connections ... -
Modeling of hot-spots in transformer using analytical or numerical methods
(Master thesis, 2023)Due to the increasing penetration of renewable energy sources into electrical grids, high variation of power becomes a problem for the stability of power systems. To keep the system balanced, hydro generators occasionally ... -
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, ... -
Monitoring 50/60Hz Grid Coupling – A Study In Conjunction with Wind-Energy Feed to Main Grids
(Master thesis, 2016)This master thesis is about investigating and comparing findings for different voltage control strategies for the 60Hz grid connection using microcontroller (Arduino). The P-Control, PI-Control, PID control and Open loop ... -
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 ... -
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 ... -
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 ... -
Power loss measurements in MV switchgear for Cigré-working group
