1. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator
Sammanfattning : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. LÄS MER
2. Hydropower generator and power system interaction
Sammanfattning : 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. LÄS MER
3. Synchronous generator and frequency converter in wind turbine applications : system design and efficiency
Sammanfattning : This report deals with an electrical system for variable-speed wind powerplants. It consists of a synchronous generator, a diode rectifier and athyristor inverter. LÄS MER
4. Dynamic Models for Mechanical Analysis of Synchronous Hydropower Generators
Sammanfattning : Hydropower generators are essential for providing electricity for daily human activities. For that reason, designing and building reliable generators contributes to a sustainable energy supply market. LÄS MER
5. Measurement and modelling of unbalanced magnetic pull in hydropower generators
Sammanfattning : Hydropower research is often perceived to be an old and exhausted field of study but with ageing equipment and the need for more intermittent operation caused by an increased share of other renewable energy sources new challenges lie ahead.The main focus of this dissertation are the electromagnetic forces resulting from nonuniform air gap flux, whether it be caused by rotor eccentricity or a faulty field winding.
