The Turbine "SETUR"
and its practical use
|
The turbine SETUR is a hydraulic motor, which is able
to function with relatively small energy input. It is able to effectively
utilize micro energies from water sources that are renewable and convert
them into useful work. General characteristics of this equipment are
concealed in the fact that this is relatively new type of equipment which is
utilizing hydraulic principles not implemented anywhere in the World. This
"Rolling Hydraulic Machine" is at the moment the only technical equipment,
which can be from the economical, ecological cleanliness, and technical
simplicity point of view installed under unstable or borderline energy
conditions. It is therefore able to successfully produce mechanical energy
with effectiveness of 65 - 75% where other apparatus for technical and
economical reasons cannot be installed. In practice, it is about potential
energy obtained form very small down grades and minimal water flow
quantities. For example effective possibilities to harvest energy present
themselves with water level differences of around 0.5 - 1.5 meters or water
volumes of 2 - 20 liters/sec passing through the turbine. In practice, these
unusually small natural water sources are not being utilized anywhere in the
world at this time, even though they represent more then half of the
worldwide hydro-energy potential. Turbine SETUR appears to be the possible
source of the driving force in the inevitable change of this negative
situation towards improvement, because it offers to its users simply,
inexpensively, and effectively to explore natural and renewable resources
where it was absolutely not possible until now.
World's innovation, new principle of function, and
simple industrial utilization of turbine SETUR and for its economical use
made it possible to obtain wide ranging coverage of patenting protection. In
most of the industrialized countries in the world the Rolling Hydraulic
Machine is patented nationally or internationally including improved
applications and technical innovations are subject to attached patenting
protection. (For example, in the USA it is the United States Patent
6,139,267, in Australia Letters Patent No. 722378, the publication of the
Euro-patent is prepared by the European Patent Office, application solutions
under the name Hydraulic Motor is registered for international patent
protection Registration PCT/CZ99/00012 etc.).
Practical utilization of turbine SETUR for the
purposes of energy harvest is prepared in two formats. The first is based on
the concept of machine for the production of small (micro) quantities of
electrical energy and the second is utilized to power a water pump for local
irrigation systems. Both of these concepts are characterized by the fact
that they enable the user to utilize minimal, in practice by other equipment
unusable, source of potential renewable energy. Past experiences prove that
from the economical sense the micro-turbine SETUR is able to pay for itself
in just a few years, if it is producing electricity, which is being
completely utilized in closed manufacturing production circuit, or in just
few months if it is equipped by a water pump and is being used for long term
irrigation of farming production. In case of need it is technically possible
to equip the turbine SETUR with both functions at the same time, which is to
power the generator as well as the water pump. Practical testing has
confirmed that micro-quantities of electrical energy, especially in an
accumulated form can save the lives or profoundly affect the lives of people
who for some reason cannot be without a source of electrical energy and have
no other means to generate it. Also the utilization of the turbine SETUR as
the source of energy to drive a water pump to irrigate a land can in its own
way act as an instrument for the survival of people in the long term or
under unexpected array of (negative) conditions. |

The Installation of Home Water Powered Electrical Generator DVE
(Practical, Simplified procedure)
|
Our Goal: Provide a sufficient quantity of electrical power
for average operation of "Our" cabin, using a nearby water source.
Before considering the installation of DVE it is necessary to do some
calculations on energy balance:
A) Source of Electrical Energy
B) Anticipated usage of Electrical Energy
A) Energy balance for water powered machine, operation of Home Water Powered
Electrical Generator:
Before we begin with the installation of the DVE, it will be necessary to
research all ownerships of land including local land and water rights,
building permits, and other applicable law and legal considerations if those
issues have not been worked out.
In the country site where "Our" cabin is built, we will give an approximate
estimate of the potential capacity to produce electrical energy from the
water which will power the generator DVE. For our calculations we need two
measurements:
1. Water down slope: H [m]
We will obtain "H" by simply measuring the differences between: upper water
level, (the point where we will install the water intake pipe) and lower
water level, (the point or location where the DVE will be installed).
In our example it was measured: H = 5m
2. Water volume: Q [l/s]
"Q" will be established at the location where the DVE will be installed by
doing a few repeated measurements. This can be done by filling a larger
container (barrel) of a known volume while timing the period needed to fill
the container with a stopwatch.
In our example it was measured:
Barrel with a volume of 200 liters; average time to fill it: 25sec.
Water flow: Q=200/25=8 l/s
Q = 8 l/s
3. Calculating the sustained output of the electrical generator
With the assumption that the entire water volume will pass through the
turbine and will produce usable energy, we will calculate the expected
energy yield on the output contacts of the generator this way:
GIVEN: Mechanical Efficiency of Turbine: hM = 0,7 (70%)
GIVEN: Efficiency of Generator: hG = 0,5 (50%)
GIVEN: Coefficient of Hydraulic Loses in water supply pipes: 0,765
Electrical output PEL:
PEL= g * Q * H * hM * hG * 0,765 =
PEL= 9,81 * 8 * 5 * 0,7 * 0,5 * 0,765 = 105W
PEL= 105 W
In Conclusion:
Our water power source (in the example above) is capable of converting its
energy potential to electrical power output of 105 W. The turbine SETUR will
be equipped with a 3-phased synchronies generator with parameters as
follows:
Output: 120 Watt
Voltage: 3x24 Volt AC (Alternating Current)
B) Energy Balance of electrical energy consumption in "Our" cabin
The basis for this calculation is "Our" useful layout of electrical devices
throughout the dwelling and their rated consumption in Watts, as it can be
seen on the next cabin floor drawing. At the same time we will establish the
expected duration of their daily operation. All findings will be laid out in
tables and from there we'll calculate electrical energy consumption.

After calculating daily consumption (see Table I.) we will select battery
voltage (12 V or 24 V DC). With regards to loses in power supply wiring it
is better to choose higher voltage: USYST=24 V
- Further we'll calculate basic capacity of Battery CA [Ah]:

Battery capacity calculated this way is for uninterrupted working regime of
DVE, without regard to its reserve capacity and without consideration to the
depth of battery cycling. It is safer to consider daily reduction of
operation of DVE max. 0,5 hour.
Coefficient for battery charging is thus:kA= 24 / (24 -
0,5) = 1,021
In order to maximize life expectancy of the batteries, the depth of
discharge should not exceed 50% of its capacity.
For those reasons the depth of discharge will be set to:hV =
0,5
- Next we'll calculate the optimum capacity of the batteries for operation
of our electrical devices:
C = CA* kA / hV = 79,125 *
1,021 / 0,5 = 161,617 Ah
From available selection of optimal battery capacities we have selected two
12Volt batteries with the rating of 80 Ah. They will be connected in series
for a total of 24 Volts:
|

Total available energy output of the selected batteries equals: C=160 Ahand
output Voltage of both batteries connected in series: U = 24 V (this
coincides with USYST)
In order to operate the most energy demanding electrical devices
simultaneously, it will be important to select appliances with a minimum
power consumption designed for 230 V, 50 Hz AC power system in "Our" cabin.
These appliances are selected as an example:
Refrigerator : 55 W
Water Pump : 180 W
Television : 50 W
Light : 13 W
Total : 298 W
From the above example it is self evident that the minimum setting of the DC
to AC converter operating at system Voltage of 24 V, has to be:
Pstr. = 300 W
The required current consumption will be partly covered by the batteries and
partly by the output of the DVE. The current on the DC side of the DC to AC
converter will be:
Istr. = PM / USYST = 300 / 24 = 12,5 A
- Since there is a sizable current required by the DC to AC converter it is
of paramount importance to properly dimension the electrical wiring. In our
case with consideration to loses of 3% in the connective cabling to both
sides (that is the + & - connections) of the DC to AC converter, wiring with
a minimum of 6mm2cross sectional dimension and a maximum length of 8m (with
wiring from batteries to the DC - AC converter). It is assumed that the
current carrying capability is 2,5 A/ mm2.
This concludes the calculations of balance between consumption, suggested
battery capacity, and output of DC to AC converter. For additional assurance
we will confirm the capabilities of the power source (DVE) on reduced daily
output in the time span from 6a.m. to 12p.m. or approximately 18 hours.
Ad = 1899 Wh / day = 24 hours
Adr = 1899 Wh / 18 hours -> will determine the continuous reduced output
during the operation "Our" live-in accommodation (cabin):
P18 = Ad / 18 = 1899 / 18 = 105,5 W
Based on our above calculations, DVE is capable of a continuous output of
PEL= 105 W
In Conclusion::
Comparing calculations and data from sections "A" and "B" we can conclude
that the output of the electrical source is sufficient for our operation. In
such case that the calculated data in P18 > PEL (greater then) is more than
5%, it will be necessary to reconsider the operation of "Our" cabin by
readjusting consumption requirements in the appropriate table (Table I.)
used above.
Should you require additional or more detailed information for the above
example and also the possibility of energy power grid setup, we will be glad
to supply it. |
