ENEC HPS presented a new river turbine design called the ENEC HPS turbine. The turbine uses blades attached to crankshafts that act as pistons in cylinders to transmit kinetic energy from flowing water to a generator via a crankshaft. Changing the blade positions allows for higher utilization of water's kinetic energy. A 5MW system uses 6 blades wrapped around each other in a 360 degree pattern. Support girders are needed due to flexing and twisting forces from the long crankshaft. The central girder can be attached to the generator to shift the center of gravity. The primary goal of this new turbine design is to transfer as much kinetic energy from water flows to a generator without large reservoirs in
3. The rods (blades) which more associate on paddles then on ordinary turbine rods are on
one side attached bearing the crank ends and the second end of the handle which acts as
a piston in the cylinder and they are together attached to a stationary shaft over which the
kinetic energy of the water flow is transmitted to the crankshaft, and from this point to
the turbine generator.
4. Changing positions of the blades of the impeller we achieve a higher level of usage of the
kinetic energy from the water flow.
On this picture we see build in six paddles from one side and six on the other and the
generator that is attached to the paddles in the middle.
5. 5MW system consist of 6 blades, which are mutually wrap around each other for ( 6 x 60° =
360°).
Blades dimensions (according to analysis):
width: 3,4m
height: 2,2m
Based on blades dimensions, it is designed whole system construction with it’s optimal
dimensions:
width: 22m
height: 26m
6. On the animated pictures above is displayed position of the supports (girders) which are
calculated in Constructional Project.
Due to use of long crancshaft, and appearance of the flexion as twisting forces, it is
necessary to apply supports (girders).
Middle support is possible to connect on generator and thereby, center of gravity is shifted
on the middle of the system.
7. On this picture we see a basic workshop model
So far are constructed various types of turbines of various technical solutions and
performances for high-downs from water reservoirs and flows to the natural flow of water,
with little exploitable effects in relation to the financial investments.
8. The primary object of the invention is to make the turbine, which will transfer as much kinetic
energy to the generator without creating large reservoirs of water, and in this way to produce
as much as possible of electric energy.
