The Research and Design of Vertical-shaft Water Turbine Power Generation Device

摘要

Under the circumstances of global climate becoming warm, the development of tidal energy which is a reproducible clean energy attracts great attention. And the effective usage of developed tidal energy is the critical problem of developing the tidal energy. Presently, the utilization rate of tidal energy is improved mostly by changing water turbine's structure, which is under research. And the refinement of already built tidal energy generating set is restricted by cost. The electronics and electric device of water turbine are designed by taking certain control strategy under the structure of water turbine unchanged. So the water turbine is run at maximum efficiency. And the tidal energy can be applied as far as possible. After experiment, the designed experimental device is up to the control requirements.
