Mainland world energy potential of underutilized water resources in TWh of electric energy production per year is achievable for such micro-hydro power also in rivers

and channels.

Market

Acceptable capacity in GW on a global scale for the use of micro-hydro power underwater river (coastal mainland) and

marine (tidal) - based to explore possible market.

Market

КȖȕкțȘș «ТехȕȖșȚаȘȚ 2014»

The cost of a KWh generated by micro-hydro electric energy compared to other sources within less than 0,01 €

taking into account the ratio of fuel and maintenance costs and payback of the construction of the power plant.

Market

According to International Rivers, the modern use of small, mini and micro-hydro power comes out to more economical

level than the construction of a large HPP.

Market

R&D Tests of model vortex turbines for micro-HPP conducted in the laboratory of hydrodynamics of the St. Petersburg State Polytechnic University and obtained positive results.

It was determined that cavitation occurred at the exit of the blade at a flow

coefficient of approximately 0.33 for the 1.5 pitch blade geometry, while the

uniform blade geometry had a value of 1.35. When the rotation rate was

reduced to 250 rpm, cavitation occurred at a flow coefficient of 0.72.

From the simulations at both rotation rates, it was determined that both

geometry and rotation rate have a significant effect on the onset of cavitation

and water vapor inception within the flow field. As the rotation rate of the

turbine decreases, the onset of cavitation will be prolonged to larger flow

coefficients. (Cavitation Phenomena and Performance Implications in

Archimedes Flow Turbines Jacob D. Riglin, William C. Schleicher and

Alparslan Oztekin).

R&D

The option to install a HPP 5 kW river based on the hanging bracket on one of the banks of the canal or river.

Design

Installation of the underwater generator at the bottom on the cradle 40 m. Option deep installation of micro-hydro in the intertidal zone along the coast or on the river bottom.

Analogues Propeller turbines can rotate at a right angle to the flow and have higher rotation speed than that caused by the danger of falling under the knife of fish and other species of flora and fauna.

Tidal turbine casting

Analogues The dimensions of the underwater hydroelectric turbines with spiral Riv GenТМ is 11 .9 m wide and 2.8 m high, 2.3 m in depth. Power output for this design is only 30 kW flow rate of 3 m/s. Comparable with the proposed design, where hydro reactor power of 20 kW and has dimensions of a length of 1.85 m and a wheel diameter of 1 m.

Financial statistics Analysis of the cost of building a micro-hydropower for the World Bank.

Features of fabrication and

operation of a portable

underwater plant provides

a comparative low cost that

allows you to compete on terms

of return of investment with any

other renewable energy sources

such as wind and solar power

plants. As can be seen from the

table, we managed to reduce the

cost of installation kilowatt of the

micro-HPP by several times, due

to the compressibility of the flow

and thus the selection is almost

entirely the kinetic energy.

Advantages over analogues:

• Horizontal vortex turbine is several times more powerful than the

existing vertical turbine Savenius technology “In stream” and completely

environmentally safe for the surrounding flora and fauna

• Turbines with small dimensions can be installed in rivers with

velocity more than 1.8 m/sec at a depth of at least 1 m from the surface.

• The receptivity of the flow is the highest of all known turbines, as there

are large surfaces washing of turbine blades

• Turbine have a high torque value on the shaft that allows the use of

inexpensive gearboxes or really do without them, using underwater

low-speed generators

• the manufacturing Costs of turbines are low, since blades can be made

on special bending machines with high performance automated production

lines for manufacturing • power Plants with a jet of spiral turbines easily

scalable , thus no need to readjust the productive line with changing

customer demand • Low cost of fabrication, construction and operation,

allows the use of such hydroelectric power plant in different abnormal

conditions and their mobility allows them to disassemble and assemble,

depending on need, allowing them to be used in the temporary grade of

plants, is much easier to get permission to use them.
