Abstract :
Favourable land formations in places with large differential tide heights can cause fast flowing tidal streams. One such tidal stream in the Northern Territory, with power densities as high as 6 kW/m2 , is the site of a kinetic tidal generator project. This paper presents the development of a high efficiency tidal generator to harness the kinetic energy present in the moving water and shows measured results from the site. It highlights the use of a high efficiency “lift” type turbine, a state of the art low-speed high-torque brushless DC machine type generator and synchronous rectifier, and a digital PID controller used to track the point of maximum power of the turbine
