Definitions

  • a pumped storage plant is currently the only practical method for large-scale storage of electrical energy.
  • a reversible pump/turbine is used to pump water up during off peak hours and then the same unit is used to generate energy during peak hours.
  • Pumped storage is a proven, economical form of energy storage that makes better use of existing capacity.
  • Facilities can be built at moderate costs as a peaking or intermediate capacity plant.
  • pumped storage provides low-cost peak energy. It has superior operating characteristics used for load-levelling and load-following duties, and provides excellent response times for automatic generation control purposes. These characteristics reduce the cycling and load-following demands on base-load plants and provide overall improvements in system reliability and operating economy.
  • the amount of power from the potential energy in water that a water turbine can generate is directly proportional to the flow (volume) of water and to the head. It requires more energy to pump a volume of water up a set head than that volume of water can generate for the same head.
  • patent US7188471 B2 An example of the prior art which is similar to this invention is patent US7188471 B2.
  • This prior art does not allow for the storage volume required by this current invention, or the separate operation modes of generating and pumping.
  • This prior art relies on "a pump for evacuating water from said enclosure, said pump calibrated to evacuate from said primary chamber approximately the same volume of water admitted into said enclosure by said intake valve.”
  • This prior art also details the pump as being operated by wave motion and being in continuous operation.
  • patent US6347910 Bl Another example of prior art which comes close (but with many differences) to the novel ideas in this present invention is detailed in patent US6347910 Bl.
  • Said prior art is a sealed unit and does not utilize the present invention required water pressure difference between the top of the body of water elevation (generally close to or at atmospheric pressure) and the elevation of the top of the water in the lower reservoir which is submerged at the bottom of the body of water, but also at the same basic air pressure as the atmosphere above the body of water.
  • This prior art relies on some kind of two stage pump system in order to operate.
  • Patent application US20030059292 is similar but used with moving water currents.
  • This disclosure also is "pressurized at a pre-determined internal pressure sufficient to offset the external pressure of the body of water in which the energy converting module is submerged" so it is doubtful it would operate efficiently since there would be little to no pressure difference.
  • the relatively shallow water depth of the SubGenStor system (not more than ⁇ 500m), separate generation and pumping/clearing modes nor the possible large output generator units along with multihour storage volume are also novel aspects of this present disclosed invention.
  • the primary object of this invention is to provide a Submerged Generation and Storage system (SubGenStor) composed of multi-megawatt turbine or pump/turbines that are capable of generating power and energy.
  • SubGenStor Submerged Generation and Storage system
  • a power-generating pump/turbine energy storage system which offers the advantage that the pump/generating units are located underwater out of visual range and can be located in close proximity to the load center.
  • This system allows multiple, modular units to be used. By the novel idea of mounting these at the bottom of a lake or ocean (any body of water) the units do not require water channels (penstocks or tailrace) of any great length.
  • Prior art allows for pump/ turbines similar to these units to enable the capture and storage of energy, but all previous have been located at or near or under the ground and do not utilize the novel idea of being submerged in what is basically its own upper reservoir.
  • Prior art also allows for various pump/turbine plants to be located around or utilize existing lakes, but none envision the arrangement of this invention.
  • the turbine or pump/turbine units are mounted in a watertight structure beneath a body of water and with the use of air vents the lower storage reservoir is kept at normal atmospheric pressure while the storage reservoir fills during generation. At the end of a period of generation or when the lower storage reservoir is filled the lower reservoir is pumped clear or forced clear of water by mechanical or pressure means. Vent tubes floating at the surface and/or access caissons will be equipped with all necessary warning devices for marine traffic.
  • Underwater cables will carry the generated energy to inverters, converters, transformers, switchgear etc. as required located on the shore and then into the electricity grid.
  • the underwater structure is designed such that it can also assist with the inlet and outlet of the water flow to and from the pump/turbine.
  • a specific object is to provide a water pump/turbine for generating power which is characterized by a modular construction and provides a high cycle efficiency at relatively low cost and without sacrifice of structural integrity.
  • the power generated could be variable frequency AC transmitted to the shore where it is converted to DC then via power electronics to pure waveform AC voltage. Power generated could also be high voltage AC or DC.
  • Still another object is the ability to provide a battery of mutually supporting power generating pump/turbines that are disposed in parallel to one another.
  • a turbine or pump/turbine that essentially comprises multi-vane input and output stator (the water distributor); a rotating turbine/impeller unit and a multi-pole rotor in a motor/generator stator.
  • Some or all of the units may include direct or gear drive from the turbine/impeller to a variable (or constant) speed electrical rotor. It is possible that a torque converter could take the place of or assist the gearbox.
  • the body of water will usually be large enough such that operation of the system will not lower or increase the upper water level any substantial amount.
  • This invention could generate at high voltage, low ampere variable frequency AC for transmission to the shore. Energy is then converted to DC, then back to a pure AC waveform to match the power grid using existing commercially available power electronics.
  • the generators can be high voltage DC for transmission to the shore and then converted to pure waveform AC to match the power grid. They could also be synchronous high voltage AC then transformed at the shore to match the power grid.
  • the turbine or pump/turbine system above functions in the Generation mode as follows: directed by the inlet shape 103 in figures water enters past the valve and into the scroll case where pressure is equalized around the distributor assembly. The water flow is controlled and made laminar (or at least substantially less turbulent) as it passes between the wicket gates of the turbine onto the turbine rotor (runner).
  • the water pressure (head difference from upper water level 108 to lower water level 115) causes the turbine rotor to rotate at a speed proportional to the flow and pressure of the water due to gravity.
  • the output shaft torque acts to drive the associated generator 101 (or gearbox then generator) thereby producing power which is transmitted to the transformer 102 then to the desired point of use by a power cable 104.
  • the area enlarges and flow is directed into the draft tube section where it expands gradually and leaves the turbine unit to enter the lower storage reservoir 109.
  • the water level of the lower storage reservoir 115 will vary based on flow and operation. In generation mode it will fill with water while air is vented to the surface either through the access shaft and air vent 106 or air equalization tubes 118 or both depending on construction. This air could possibly be used to operate a Wells type turbine 117 & 120 to generate additional energy.
  • the system operates as follows: when the lower storage reservoir 109 is full and/or excess power is available in the system the unit is switched to pump mode which enables the water in the reservoir to be forced back into the main body of water.
  • the power flow is reversed and the generator/motor 101 spins in reverse which causes the turbine/impeller to suck water back through the draft tube and force the water back out the distributor gates past the valve and back into the main water body.
  • the water level 115 changes air is vented back into the reservoir through the access shaft and air vent 106 or air equalization tubes 118 or both depending on construction. This air could be used to operate a Wells type turbine 117 & 120 to generate additional energy.
  • the preferred method is to use a normal hydroelectric unit to generate the energy the same steps would occur during generation, but the clearing of the lower storage reservoir would occur by sealing the air vent 111 or air equalization tubes 118 or both and using high pressure air to purge the lower storage reservoir through multiple check valves 125 whose inlet is located below the top of the ballast water 110 area then discharge straight out or travel up the side of the reservoir discharging near the top of the lower reservoir.
  • An optional feature of the invention is to provide the intake/discharge sections with a coating and making such surfaces smoother so as to promote higher efficiency flow. Similar coatings may be applied to the exposed surfaces of the pump/turbine for the same or other reasons (possibly to prevent marine growth).
  • the station could also be designed using a conventional hydroelectric turbine and storage for compressed air 123. The compressed air could be used to purge the water from the lower reservoir when it is full by sealing the vents. The compressed air could be supplied from wind turbines 124 which operate as compressors and/or electrically driven compressors.
  • the electrical motor/generating units may be Alternating Current or Direct Current motor/generators and that they may be located within the airtight module, outside the module or both.
  • Another possible modification is to have more than one rotor on a shaft, with the number of stator stages increased correspondingly .

Abstract

L'invention porte sur un système de Génération et de Stockage Immergé (SubGenStor) constitué par des turbines ou des pompes/turbines de plusieurs mégawatts, qui sont capables de stocker et de générer de l'énergie renouvelable. Le but de cette invention est de créer un ensemble station de stockage et de génération d'énergie renouvelable écologique et virtuellement invisible, constitué en majeure partie par des composants disponibles dans le commerce ou des composants dont le développement est actuellement très avancé (à savoir, des composants et une construction sous-marins modulaires). Cette invention utilise des réservoirs de stockage inférieurs immergés réalisés par l'homme, montés sur le fond de la masse d'eau, lesquels réservoirs sont à la même pression que l'air directement au-dessus du niveau d'eau supérieur de la masse d'eau dans laquelle ils sont disposés, et sont évacués vers celui-ci. La capacité d'énergie et la durée sont limitées uniquement par la profondeur de fonctionnement et par la taille du réservoir de stockage inférieur. Ces installations pourraient être disposées à proximité de centres de charge, tels que des villes, le long de zones côtières. Un avantage supplémentaire peut être obtenu lorsqu'ils sont disposés dans une zone soumise aux marées. Comme un procédé de génération par les marées peut être utilisé, de l'énergie peut être générée lorsque la marée est haute, et moins d'énergie peut être utilisée si le réservoir est vidé/pompé lorsque la marée est basse. Le rendement de cycle peut alors être rendu maximal en fonction de l'ampleur des marées. Le réservoir inférieur et les structures sous-marines associées pourraient également être utilisés pour ancrer ou supporter des éoliennes en mer pour délivrer de l'énergie renouvelable supplémentaire sous la forme d'air à haute pression ou d'électricité.
