Hydro Kinetic Water Poncelet: 100 - 1,000 kW
The Energetic Drives engineering team worked with Hasz Consulting and Whitestone Power of Alaska to develop a state-of-the-art hydro kinetic turbine dubbed the Poncelet. This design
incorporates electrical engineering design, controls engineering development
and substantial research and development skill sets.
All mechanical components, designed by Hasz Consulting with minor oversight by the Energetic Drives
team, proved to exceed initial requirements in all categories.
The design criteria called for the Hydro Kinetic Turbine to be placed on
the surface of a river. Fish and
Wildlife required a low draught of the paddles and low speeds. This would
minimize disturbing the fish species in the local rivers.
The solution required a direct connect to a load (i.e., a village) with an option
for grid distribution. In order to
achieve this, Energetic Drives employed a Parker grid-tie inverter design with
unique control and function blocks enabling a “load demand, load adapt function”
consistent with UL 1741.
Finally, the unit needed to work in conjunction with exisiting diesel
generators currently being used in rural Alaska. The system would work in tandem with the
primary diesel in an iscochronous mode.
A very difficult proposition indeed!
Energetic Drives with Hasz Consulting
and Whitestone Power submitted the proposed design and gained approval from the
Fish and Wildlife of Alaska in 2011 after all criteria were met through many
hours of research and development.
above isolates the key components used to supply the system solution. The mule boat enables the poncelet to be used at multiple
locations on the river or along the shoreline.
magnet generator provides ultra-high efficiency energy conversion using 48
magnetic poles made of rare earth Neodymium magnets.
The grid-tie inverter, the smallest in class, provides
high efficiency conversion from AC to DC and re-inverting to AC in order to
provide 3 phase 60 Hz power at all speeds of rotation and flow of the river. A
global power supply is incorporated for deployment world-wide (380V, 460V, 575V and
690 volt 3-phase is standard).
Aluminum wheels provide light-weight structure and strength to the design. In
addition, the Poncelet's flotation pontoons are designed to float even if debris
were to breach the skin.
