6. 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

7. Demagnetization and Fault Simulations of Permanent Magnet Generators
Abstract : Permanent magnets are today widely used in electrical machines of all sorts. With their increase in popularity, the amount of research has increased as well. In the wind power project at Uppsala University permanent magnet synchronous generators have been studied for over a decade. READ MORE

8. Magnetic Leakage Fields and End Region Eddy Current Power Losses in Synchronous Generators
Abstract : The conversion of mechanical energy to electrical energy is done mainly with synchronous generators. They are used in hydropower generators and nuclear plants that presently account for about 80% of the electric energy production in Sweden. READ MORE

9. Direct Driven Generators for Vertical Axis Wind Turbines
Abstract : Wind power is a renewable energy source that is increasingly used all over the world. Most wind turbines have a horizontal axis of rotation but a few have a vertical axis of rotation. The concept presented in this thesis is a straight-bladed vertical axis wind turbine with a direct driven cable-wound permanent magnet synchronous generator. READ MORE
