Definitions

  • the present invention relates to a combined apparatus, of the "stand alone” type, for power production from discontinuous renewable sources and for the treatment of water, in particular for small powers from 1 KW to 5 KW.
  • the invention relates also to a method for managing a combined apparatus as outlined above.
  • Systems for power production from renewable sources of the "stand alone” type are characterized in that they are not connected to the electricity mains. In such cases the system directly produces and delivers the electricity that satisfies all energetic needs.
  • Systems of this type are known as “Stand Alone” systems and differ from the Grid systems, which are connected to the mains.
  • Photovoltaic and wind power systems are the most common and known among the stand alone systems. Photovoltaic systems are widely applied and widespread in road traffic signs and visual signs. The photovoltaic panel catches the sun energy in the daytime and supplies an accumulator. In the night time the accumulated power is released to supply the lamp and the electronic control system.
  • Stand alone photovoltaic and/or wind power systems are widely used in the areas that are not reached by the electric power mains, to supply home users or small industrial users.
  • systems of this type are widely used in the distant places of the planet, or in adverse weather conditions, such as deserts, polar regions, or the like.
  • the stand alone systems are constituted by few essential elements, described briefly later on.
  • the photovoltaic modules and/or wind turbines are aimed at collecting the solar energy.
  • the charge controller is a component that manages the produced energy. Normally, the electric power has a stabilized voltage of 12 or 24 Volt.
  • the charge controller disconnects the photovoltaic system and/or the wind turbines from the battery, when the latter is charged and in case of low voltage (e.g. night off-peaks) or voltage returns from the battery to the panels.
  • Storage batteries are necessary to store the power produced by the photovoltaic modules, which are discontinuous type renewable sources, and stabilized by the charge controller, so as to allow its deferred use.
  • the batteries allow the postponed use of the energy produced in a discontinuous way by photovoltaic modules, however possibility of continuous energy use 24 hours a day cannot be ensured.
  • Inverters are means for converting the direct current in alternating current.
  • Output current from the inverters has normally a standard voltage of 1 10 or 220 volt to allow supplying power to the electric/electronic destination devices.
  • the stand alone systems are more expensive with respect to the systems connected to the electricity mains due to the batteries, which allow to postpone the power delivery with respect to its production, however, they allow having electric power available also in places not reached by the electricity mains.
  • the conventional stand alone photovoltaic and/or wind power systems are little versatile and require specific design costs each time, since all the system elements must be determined and chosen one by one, depending on the installation type, and it is necessary to analyze the way of fastening to the support structures present on the spot.
  • drinking water must be supplied by water trucks or other transport means, or it must be produced in loco by means of purification systems.
  • the object of the present invention is to propose a combined, stand alone type apparatus, which includes means for producing energy from renewable sources and an optimized water treatment system.
  • Another object of the present invention is to propose a versatile and easy-to-install combined apparatus for producing electric power and drinking water in a continuous way from discontinuous renewable sources, which is capable of using both freshwater (also in presence of polluting substances) and brackish water.
  • a further object of the present invention is to propose a combined apparatus for producing electric power and drinking water, which is capable of receiving and managing the power coming simultaneously from a plurality of sources of different types.
  • a still further object of the present invention is to propose a method for managing the electric power produced by a plurality of sources of different types.
  • a combined apparatus for producing electric power and drinking water which includes a section that transforms the power produced by renewable sources that can be used in electric power production systems of the stand alone type, comprising:
  • At least a charge controller for controlling the electric power passage to/from said batteries
  • a portable container provided at least with: AC electric power input connecting means, DC electric power input connecting means, AC electric power output connecting means.
  • a combined apparatus according to the invention includes also a water treating system powered by the energy converting section and comprising inlet piping for water to be purified.
  • the elements of said apparatus are connected according to a three-phase wiring diagram to supply a three-phase AC output connection.
  • the components of said apparatus are connected according to a single-phase wiring diagram to supply at least a single-phase AC output.
  • An apparatus as outlined above can be connected to a plurality of types of electric power sources, preferably renewable sources, and it transforms the input power so as to make it usable for various types of usages, both industrial and domestic.
  • a main usage of the produced power is that of a water treating system, integrated directly into the apparatus.
  • An apparatus according to the present invention is very versatile, since it allows to connect various types of power sources without the necessity of re-designing and modifying the system components at each installation and allows delivery of the electric power and drinking water in a continuous flow 24 hours a day in the areas not reached by the electricity mains. Furthermore, the apparatus of the invention is very practical, since all the components are housed in a single portable container, correctly set previously and connected one to another so as to make its installation very quick. Due to its compact structure, the pre-installed and pre-configured modules, and to the use of renewable sources for the power production, the combined apparatus of the invention is particularly suitable to be used in the distant regions of the planet, since its installation does not require skilled labour, its operation is completely automatic and it has no environmental impact.
  • the combined apparatus of the invention includes a plurality of photovoltaic modules connected directly to the apparatus structure, so as to pass from a compact transport configuration to an extended, power production configuration.
  • the energy production by means of integrated photovoltaic modules, in an apparatus of the invention of medium dimensions, allows saving more than 10 tons of diesel fuel a year and to reduce the C02 emissions by more than 80% (for the production of the same amount of electric energy by motor generators of the conventional type).
  • the above mentioned objects are achieved by means of a method for managing the electric power produced by multiple power sources of different types in an apparatus for converting electric power comprising at least an inverter, electric power storage batteries and at least a charge controller for controlling the flow of electric power to/from said electric batteries, in which the apparatus is provided with at least an input connecting means for DC power produced by photovoltaic generators, at least an input connecting means for DC power produced by wind power generators and at least an AC power input connecting means, in which the method comprises a step of activating the flow of electric power from the above mentioned power sources for charging the electric batteries according to a predetermined sequence and a step of interrupting the flow of electric power by the above mentioned connecting means according to a further predetermined sequence, when the charge level of said batteries reaches specified values.
