| Summary: | The renewable energy such as solar and wind energy has been developed
rapidly for decades, but the research in tidal stream turbine is just booming in recent
years. Tidal energy has various advantages as a renewable energy source, such as
clean, predicted. And the good use of tidal energy is a good target to discover for
clean and sustainable energy resources. Hence it is important to understand and
optimize the performance of the turbine and maximize the power harvesting under
different working conditions. The keys of this project are to build up a model of
variable-speed stream tidal turbine equipped with permanent magnet synchronous
generator (PMSG) and control this model. This project can be divided into two
portions: system modeling and controller design. The modeling work will be
implemented in Matlab environment. The target of the control part is to keep system
harness maximum power from flowing waves at variable tidal speed. After
adjustment of the controller, stable and efficient output can be obtained. Different
controllers will be designed to satisfy different working conditions. |
