Description

SYSTEM FOR GENERATING ELECTRIC POWER BY VIRTUE OF HYDROSTATIC ENERGY AND METHOD THEREOF

TECHNICAL FIELD

[001] The present disclosure relates to the field of generating electric power. More particularly, the present disclosure relates to a system and method for generating electric power by virtue of hydrostatic energy.

BACKGROUND

[002] Consumption of electricity has increased in each and every sector like industrial, domestic, agriculture etc. This has led to a greater demand for power generation. The different methods available to generate power are hydro, thermal, solar, wind, nuclear etc. But all of these methods are used to generate power at a large scale and also they require more expenditure in terms of installation and configuration of heavy machinery.

[003] Typically, the hydro power generation requires a large amount of water and construction of a storage structure. The hydro power generation is highly expensive and also time and cost required to construct the project's cost is high.

[004] In the light of aforementioned discussion there exists a need for a system and method that would ameliorate or overcome the above mentioned disadvantages.

[018] It is to be understood that the present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The present disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

[019] The use of "including", "comprising" or "having" and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. The terms "a" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. Further, the use of terms "first", "second", and "third", and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

[020] Referring to FIG. 1 is a block diagram 100 depicting a system for generating electric power, according to exemplary embodiments of the present disclosure. The block diagram depicts a water head container unit 102, a turbine unit 104, a pump unit 106 and a generator unit 108. The water head container unit 102 is used to provide storage of water for supplying. The turbine unit 104 is a rotary machine that generates electric power. The pump unit 106 is a device that pumps water from the water. The generator unit 108 is a device that converts mechanical energy to electrical energy for use in an external circuit.

[021] Referring to FIG. 2A - FIG. 2D are diagrams 200a- 200d depicting various configurations of closed conduit systems for generating electric power by virtue of hydrostatic energy, according to exemplary embodiments of the present disclosure. The closed conduit assembly includes a flow pipe 202, a water head container 204, water 206 flow by means of hydrostatic energy 206 at stable state, a turbine 208, for example a reactive turbine, multiple pumps 210a - 210c, for example centrifugal pumps and a generator 212. The water head container 204 is elevated at predetermined height with an inlet 204a and an outlet 204b. The inlet of the flow pipe 202a connected to an outlet of the water head container 204b for allowing flow of water 206 from the water head container 204 by virtue of hydrostatic energy.

[022] As shown in FIG. 2A - FIG. 2D, the turbine inlet 208a allows the flow of water 206 from the outlet of the water head container 204b and discharges to the turbine outlet 208b. Furthermore a generator 212 is connected to the turbine 208. The inlet of the pump 210d configured for collecting the discharged water 206 by virtue of gravitational energy from the turbine outlet 208b and pass through the outlet of the pump 210e. Water 206 flows from the outlet of the pump 210e to the water head container 204a by means of hydrostatic energy resulting in formation of the closed conduit of water with hydrostatic energy in a static state.

[023] As shown in FIG. 2A - FIG. 2D, switching on the pump 210a initiates pumping of water from the outlet of the pump 210e using the captive electric power resulting in continuous flow from the water head container 204 followed by striking the turbine 208 resulting in rotation of the turbine 208 and passing through the at least one pump 210e to the inlet of the water head container 210d resulting in generation of electric power. The generated electric power is higher than the captive electric power. The captive electric power here may be referred as input electric power to activate the pump.

[024] Referring to FIG. 3 is a diagram 300 depicting results obtained from various head heights of water container and flow of water by virtue of hydrostatic energy for generating hydrostatic energy, according to exemplary embodiments of the present disclosure. FIG. 3 represents calculation of amount of power consumption by pump from the below formula:

Pp=Q*H*G*W/n

, Q = Discharge of water M³/Sec

G = Gravitational force 9.81 m/sec²

H = Head of pump=suction head+ delivery head+ friction head n = Efficiency of pump

W = Specific weight of water 1000 kg/m³

Pp = power consumption by pump in watts.

FIG. 3 also represents calculation of power generation by turbine from the below formula:

Pg =Q*H*G*W*n

Here, Q = Discharge of water M³/Sec (302)

G = Gravitational force 9.81 m/sec² (304)

H = Hydraulic head (306)

n = Efficiency of turbine (308)

W = Specific weight of water 1000 kg/m³ (310)

Pg = power generation by turbine in watts (312).

[025] As shown in FIG. 3, as a first example configuration, power (Pg) of 2322W may be generated by using discharge of water (Q) as 0.042 M³/sec, head of pump (H) is 9.3m and efficiency (n) of turbine as 0.6. As a second example configuration, 58342W of power generation can be generated by using discharge of water (Q) as 0.144 M³/sec, head of pump as (H) 59m and efficiency (n) of turbine as 0.7, without limiting the scope of the disclosure. [026] Referring to FIG. 4 is a flow diagram 400 depicting a method for generating electric power by means of hydrostatic energy, according to exemplary embodiments of the present disclosure. The method starts at step 402 by enabling a flow of water from an outlet of a water head container through a flow pipe by virtue of gravitational energy. The method continues to next step 404 by discharging the flow of water from the outlet of the water head container to an inlet of a turbine. The method continues to next step 406 by collecting the discharged water from the turbine outlet to the inlet of at least one pump and pass through the outlet of the at least one pump.

[027] As shown in FIG. 4, the method continues to next step 408 by discharging the water from the outlet of the at least one pump to the inlet of the water head container by virtue of hydrostatic energy resulting in formation of a closed conduit of water with hydrostatic energy at stable state. The method continues to next step 410 by switching on the at least one pump for initiating the pumping of water using the captive electric power resulting in continuous circultion of water from outlet of the water head container to the inlet of the water head container. The method continues to next step 412 for generation of electric power by the generator connected to the turbine in response to the rotation of the turbine in response to water striking the turbine.

[028] The present disclosure has been described in terms of certain preferred embodiments and illustrations thereof, other embodiments and modifications to preferred embodiments may be possible that are within the principles and spirit of the invention. The above descriptions and figures are therefore to be regarded as illustrative and not restrictive.

[029] Thus the scope of the present disclosure is defined by the appended claims and includes both combinations and sub combinations of the various features described herein above as well as variations and modifications thereof, which would occur to persons skilled in the art upon reading the foregoing description.
