Abstract
This paper proposesthe design process and performance of an Urban Water-pipeline Energy Harvester (UWEH) System. The UWEH system design is broadly divided into two parts, namely, the electromagnetic and mechanical subsections modeling. The electromagnetic modeling includes the selection, design, prototyping and performance testing of a 65-kW permanent magnet synchronous generator (PMSG) which runs at the rated speed of 500 rpm. The mechanical modeling includes the installation, bearing selection, propeller system integration and waterproof sealing mechanism of the whole UWEH system for the field test. Detailed information on practical implementation is highlighted. Finally, based on the lessons learned from the problem associated with the mechanical subsection, a bearing-less buoyant rotor mechanism is proposed explaining its airgap control mechanism.
