1. Hydropower generator and power system interaction
Abstract : After decades of routine operation, the hydropower industry faces new challenges. Large-scale integration of other renewable sources of generation in the power system accentuates the role of hydropower as a regulating resource. READ MORE

2. Internal Design of a Class of Self-Excited Synchronous Generators
Abstract : INTERNAL DESIGN OF A CLASS OF SELF-EXCITEDABSTRACTWith the increasing trend of distributed generation and the need for alternative and renewable energy sources, self-excited induction and synchronous reluctance generators have attracted more attention for wind, tidal and hydropower applications. This thesis is concerned with the development of a class of self-excited synchronous reluctance generators (SRG). READ MORE

3. 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

4. A New Paradigm for Large Brushless Hydrogenerators : Advantages Beyond the Static System
Abstract : The grid code, FIKS, from the Norwegian transmission system operator (TSO), Statnett, states that synchronous generators > 25MVA, must have a static excitation system. However, an improved brushless excitation system is in operation on some commercial power plants (36MVA, 93.75rpm & 52MVA, 166. READ MORE

5. Comparison of Different Electrical Machines for Belt-driven Alternator and Starter
Abstract : This thesis focuses on the electromagnetic design of a synchronous machine suited for a belt-driven alternator and starter (BAS) in a micro hybridisation of a mid-size passenger car. The BAS needs to provide a high cranking torque to start the combustion engine, especially in a cool condition where the requirements are highest. READ MORE
