High current arc erosion on copper electrodes in air
(Journal article; Peer reviewed, 2011)An arc fault inside metal enclosed switchgear will cause the pressure to rise and vaporization of electrode material may contribute to the pressure rise. An experimental study of high current arc erosion on copper electrodes ... -
Model based control for run-of-river system. Part 1: Model implementation and tuning
(Journal article; Peer reviewed, 2015)Optimal operation and control of a run-of-river hydro power plant depends on good knowledge of the elements of the plant in the form of models. River reaches are often considered shallow channels with free surfaces. A ... -
Model based control for run-of-river system. Part 2: Comparison of control structures
(Journal article; Peer reviewed, 2015)Optimal operation and control of a run-of-river hydro power plant depend on good knowledge of the elements of the plant in the form of models. Both the control architecture of the system, i.e. the choice of inputs and ... -
Modeling and optimization of coolant channel cross sections in induction heating coils
(Journal article; Peer reviewed, 2011)In induction heating applications where high currents and intermittent power application dominate, thermal fatigue can be a limiting factor of the service life of the induction coil. The outer geometry of the coil is often ... -
Modeling for control of run-of-river power plant Grønvollsfoss
(Journal article; Peer reviewed, 2015-11-25)Design of optimal operation and control of a run-of-river hydro power plant depends on good models for the elements of the plant. River reaches are often considered to be shallow channels with free surface flow. A typical ... -
Modelling and control of a typical high head hydropower plant
(Conference object; Peer reviewed, 2011)This paper describes an effective mathematical model of a hydropower plant and how a decentralized control strategy for frequency and terminal voltage can be simulated. Several dynamic equations are presented for each ... -
Modelling the System Dynamics of Islanding Asynchronous Generators
(Journal article; Peer reviewed, 2014-03)Asynchronous generators are often used for small hydro power stations with an installed power capacity of under 1MW. The reason for this is their robustness and low cost. In order do be able to produce active electrical ... -
Power System Stability Using Modelica
(Journal article; Peer reviewed, 2014-12-09)This paper is concerned with power system modeling using the Modelica language in comparison to a traditional simulation tool. Though most common power system simulation tools are computationally efficient and reasonably ... -
Small scale arc fault testing of medium voltage metal enclosed switchgear
(Journal article; Peer reviewed, 2016-03-16)Internal arc fault tests are important for ensuring the safety of medium-voltage metal-enclosed switchgears. Since these tests are conducted at full scale, the costs of the test objects as well as the high-power laboratory ... -
Steady-state analysis and voltage control of self-excited induction generator (SEIG)
(Chapter; Peer reviewed, 2012)Self-Excited Induction Generators have become the prime choice for wind energy conversion in remote and rural areas due to many advantages over Grid Connected Induction Generators. However, their main drawback is poor ...
