16. Fast-response rotating brushless exciters for improved stability of synchronous generators
Abstract : The Norwegian Network Code FIKS from the Norwegian Transmission System Operator (TSO) Statnett, states that synchronous generators ≥ 25 MVA must have a static excitation system. It also includes requirements on the step time response and the available field winding ceiling voltage of the excitation system. READ MORE

18. Contributions to the electromechanics of unbalanced magnetic pull in a synchronous hydropower generator
Abstract : Misalignment between the rotor geometrical axis and the geometrical stator axis in a hydropower generator is usually present at standstill and when the machine is under operation. Now, rotor-stator eccentricity in a rotating electrical machine is a harbinger to abnormal operating conditions of the machine. READ MORE

19. Analysis and Control Aspects of Brushless Induction Machines with Rotating Power Electronic Converters
Abstract : This thesis deals with the steady-state, dynamic and control aspects of new type of brushless configuration of a doubly-fed induction machine in which the slip rings and carbon brushes are replaced by rotating power electronics and a rotating exciter. The aim is to study the stability of this novel configuration of the generator under mechanical and grid disturbances for wind power applications. READ MORE

20. On Design and Analysis of a Novel Transverse Flux Generator for Direct-driven Wind Application
Abstract : This thesis deals with the analysis of a permanent magnet synchronous generator suited for direct-drivenwind turbines inmegawatt class. The higher specific torque and power density of a transverse flux permanent magnet machine in comparison to conventional radial-flux machines make it a promising solution for direct-driven wind turbine generators.
