Description

SYSTEME DE STOCKAGE D'ENERGIE PAR AIR SOUS PRESSION ENTRAINE PAR EOLIENNEENERGY STORAGE SYSTEM BY PRESSURIZED AIR DRIVEN BY WIND TURBINE
L'invention a pour objet un procédé et un dispositif de production d'énergie électrique à partir d'une énergie renouvelable, notamment par stockage d'énergie potentielle.The subject of the invention is a method and a device for producing electrical energy from renewable energy, in particular by storing potential energy.
Il existe dans l'art antérieur un certain nombre de dispositifs de production d'énergie électrique à partir d'une énergie renouvelable. Tous ces dispositifs ont en commun qu'ils cherchent à transformer directement l'énergie renouvelable en énergie électrique, vapeur ou eau chaude. Dans ces dispositifs, on observe généralement une déperdition importante de l'énergie renouvelable utilisée, et sa conversion en énergie électrique se fait en général avec un rendement très faible (de l'ordre de 15 %). De ce fait, les dispositifs de l'art antérieur sont relativement peu utilisés, ou seulement pour des installations qui ne peuvent pas bénéficier de l'alimentation électrique générale.In the prior art, there are a number of devices for producing electrical energy from renewable energy. All these devices have in common that they seek to transform renewable energy directly into electrical energy, steam or hot water. In these devices, there is generally a significant loss of renewable energy used, and its conversion into electrical energy is generally done with a very low efficiency (of the order of 15%). As a result, the devices of the prior art are relatively little used, or only for installations which cannot benefit from the general electrical supply.
Pour notamment remédier à ces inconvénients, le but principal de la présente invention est de proposer un procédé de production d'énergie électrique à partir d'une énergie renouvelable qui est tel que la conversion de l'énergie renouvelable en énergie électrique est une suite d'opérations intégrées fonctionnant toutes en synergie. De plus, une partie de l'énergie électrique obtenue selon ce procédé est utilisée pour l'accomplissement de certaines des opérations nécessaires à cette conversion.To remedy these drawbacks in particular, the main object of the present invention is to propose a method for producing electrical energy from renewable energy which is such that the conversion of renewable energy into electrical energy is a series of integrated operations all working in synergy. In addition, part of the electrical energy obtained by this process is used for the performance of some of the operations necessary for this conversion.
Un autre but de l'invention est de proposer un dispositif de mise en oeuvre du procédé selon l'invention. Le dispositif selon l'invention est un dispositif qui fonctionne "en boucle", c'est à dire dans lequel une partie de l'énergie électrique produite est réutilisée pour le fonctionnement du dispositif.Another object of the invention is to propose a device for implementing the method according to the invention. The device according to the invention is a device which operates "in a loop", that is to say in which part of the electrical energy produced is reused for the operation of the device.
La mise en route du dispositif est réalisée entièrement à partir de l'énergie renouvelable, qui est captée et stockée. Par la suite, le système fonctionnant en boucle, l'énergie renouvelable sera utilisée uniquement pour pourvoir au remplacement de l'énergie potentielle qui a été déstockée, et pour optimiser les rendements des différentes étapes. Ce dispositif est particulièrement intéressant, dans la mesure où, grâce à l'amplification mécanique, il fonctionne comme un "levier à énergie".The device is started up entirely from renewable energy, which is captured and stored. Thereafter, the system operating in a loop, the renewable energy will be used only to provide for the replacement of the potential energy which has been destocked, and to optimize the yields of the different stages. This device is particularly interesting, insofar as, thanks to mechanical amplification, it functions as an "energy lever".
Ainsi, le choix de la dimension du dispositif ne dépend pas uniquement de l'importance ni de l'intensité de l'énergie renouvelable susceptible d'être captée, mais du besoin final en électricité. Toutefois, une bonne connaissance et une maîtrise parfaite du gisement naturel seront indispensables pour optimiser les performances du dispositif.Thus, the choice of the size of the device does not depend solely on the size and intensity of the renewable energy likely to be captured, but on the final need for electricity. However, a good knowledge and perfect mastery of the natural deposit will be essential to optimize the performance of the system.
Les opérations intégrées du procédé selon l'invention sont les suivantes : on capte une énergie renouvelable, - on utilise cette énergie renouvelable pour comprimer un gaz, on stocke ce gas comprimé à froid, on le déstocke ensuite de manière contrôlée, on convertit l'énergie issue de ce déstockage en énergie mécanique au moyen d'un dispositif mécanique, - cette énergie mécanique produite étant à son tour, convertie en énergie électrique.The integrated operations of the process according to the invention are as follows: we capture renewable energy, - we use this renewable energy to compress a gas, we store this compressed gas cold, we then destock it in a controlled manner, we convert the energy resulting from this destocking into mechanical energy by means of a mechanical device, - this mechanical energy produced being in turn converted into electrical energy.
L'énergie renouvelable utilisée peut être le vent, le soleil, ou toute autre énergie renouvelable. Cette énergie, captée, va servir à actionner un ou plusieurs surpresseurs pneumatiques qui vont comprimer un gaz. Le gaz comprimé est ensuite stocké à froid dans différents réservoirs et à différentes pressions. De manière préférentielle, le gaz utilisé est de l'air.The renewable energy used can be wind, sun, or any other renewable energy. This energy, captured, will be used to activate one or more pneumatic boosters which will compress a gas. The compressed gas is then stored cold in different tanks and at different pressures. Preferably, the gas used is air.
Le déstockage du gaz comprimé est réalisé par chauffage. Ce chauffage provient soit des calories qui sont récupérées à divers points du dispositif (notamment au niveau des compresseurs ou des turbines), soit de l'énergie captée par des capteurs solaires, soit d'une résistance électrique alimentée par de l'électricité produite par le procédé selon l'invention, soit encore par tout autre procédé de chauffage. Le gaz comprimé chauffé va pénétrer dans un dispositif de circulation des fluides tel que, notamment, un système de pompage. Ce système de pompage comprend une ou plusieurs pompes telles que notamment des pompes hydrauliques, des pompes à vis sans fin, des pompes à membranes, des pompes centrifuges, des pompes à pistons mécaniques simple effet ou double effet, l'action desdites pompes étant éventuellement amplifiée par des vérins hydrauliques.The destocking of the compressed gas is carried out by heating. This heating comes either from the calories which are recovered at various points of the device (in particular at the level of the compressors or the turbines), or from the energy captured by solar collectors, or from an electrical resistance supplied by the electricity produced by the process according to the invention, or again by any other heating process. The heated compressed gas will enter a fluid circulation device such as, in particular, a pumping system. This pumping system comprises one or more pumps such as, in particular, hydraulic pumps, worm pumps, diaphragm pumps, centrifugal pumps, single acting or double acting mechanical piston pumps, the action of said pumps possibly being amplified by hydraulic cylinders.
L'électricité produite par le procédé selon l'invention est utilisée de deux manières différentes : une partie de cette électricité est utilisée pour permettre la réalisation ou l'optimisation de certaines étapes du procédé (compression du gaz, déstockage du gaz comprimé, fonctionnement de la turbomachine), l'autre partie de l'électricité est destinée à être transmise au réseau national d'électricité ou à être utilisée sur place conformément à la réglementation en vigueur ou éventuellement transmise à un utilisateur final.The electricity produced by the process according to the invention is used in two different ways: part of this electricity is used to allow the realization or the optimization of certain stages of the process (compression of the gas, destocking of the compressed gas, operation of the turbomachine), the other part of the electricity is intended to be transmitted to the national electricity network or to be used on site in accordance with the regulations in force or possibly transmitted to an end user.
Le dispositif selon l'invention est un dispositif de mise en oeuvre du procédé ci-dessus décrit, caractérisé en ce que : il comprend un moyen de capter une énergie renouvelable et de la convertir de manière à faire fonctionner un ou plusieurs surpresseurs pneumatiques, un moyen de stocker du gaz comprimé à froid, puis de le déstocker par chauffage contrôlé pour actionner un dispositif de circulation des fluides qui expulsera un fluide spécial vers une turbomachine capable de produire de l'électricité, et l'énergie ainsi produite sert à alimenter les différents moyens dudit dispositif.The device according to the invention is a device for implementing the method described above, characterized in that: it comprises a means of capturing renewable energy and of converting it so as to operate one or more pneumatic boosters, a means of storing compressed gas cold, then of destocking it by controlled heating to actuate a device of circulation of fluids which will expel a special fluid towards a turbomachine capable of producing electricity, and the energy thus produced is used to supply the different means of said device.
Ainsi, le dispositif selon l'invention peut être alimenté par une source extérieure, l'énergie renouvelable, et/ou par une source interne, l'énergie produite par ce même dispositif. Par ailleurs, du fait de l'utilisation "en boucle", l'opérateur qui surveille le dispositif a une possibilité d'intervention et de contrôle à plusieurs niveaux notamment en intervenant sur les débits de circulation de gaz et de fluide, et en régulant la quantité d'énergie à redistribuer dans le système, il peut faire varier et optimiser le fonctionnement du dispositif.Thus, the device according to the invention can be powered by an external source, renewable energy, and / or by an internal source, the energy produced by this same device. Furthermore, due to the "loop" use, the operator who monitors the device has the possibility of intervention and control at several levels, in particular by intervening on the flow rates of gas and fluid, and by regulating the amount of energy to be redistributed in the system, it can vary and optimize the operation of the device.
La description détaillée qui suit se réfère à la figure unique jointe qui illustre non limitativement l'invention, et qui fait ressortir d'autres particularités et avantages de l'invention.The detailed description which follows refers to the attached single figure which illustrates, without limitation, the invention, and which highlights other features and advantages of the invention.
Cette figure unique est un schéma du dispositif de mise en oeuvre du procédé de production d'énergie électrique à partir d'une énergie renouvelable selon l'invention.This single figure is a diagram of the device for implementing the method of producing electrical energy from renewable energy according to the invention.
Cette figure unique représente un moyen 1 de capter une énergie renouvelable. Suivant un mode de réalisation particulier de l'invention, l'énergie renouvelable utilisée est le vent, et le moyen 1 est une éolienne. L'énergie ainsi captée sert à faire fonctionner un ou plusieurs surpresseurs pneumatiques ou un ou plusieurs compresseurs 2, qui ont pour action de comprimer un gaz, tel que notamment l'air.This unique figure represents a means 1 of capturing renewable energy. According to a particular embodiment of the invention, the renewable energy used is the wind, and the means 1 is a wind turbine. The energy thus captured is used to operate one or more pneumatic boosters or one or more compressors 2, which act to compress a gas, such as in particular air.
Selon un mode de réalisation particulier de l'invention, le gaz comprimé peut être stocké à froid dans différents réservoirs 3a, 3b, 3c, et à différentes pressions.According to a particular embodiment of the invention, the compressed gas can be stored cold in different tanks 3a, 3b, 3c, and at different pressures.
Le gaz comprimé est ensuite déstocké par chauffage. Les différents moyens de chauffage que l'on peut employer sont notamment une résistance électrique 4a, la chaleur provenant du récupérateur de chaleur 4b, ou les capteurs solaires 4c.The compressed gas is then destocked by heating. The different heating means that can be used are in particular an electrical resistance 4a, the heat coming from the heat recovery unit 4b, or the solar collectors 4c.
Le gaz comprimé ainsi déstocké actionne un dispositif mécanique de circulation des fluides 5.The compressed gas thus removed from storage actuates a mechanical device for circulating the fluids 5.
Le dispositif mécanique de circulation des fluides 5 est constitué par une ou plusieurs pompes à aspiration et à refoulement, telles que des pompes hydrauliques et/ou des pompes à vis sans fin, et/ou des pompes à membranes, et/ou des pompes centrifuges, et/ou des pompes à pistons mécaniques simple effet ou double effet. Il s'agit d'une station de pompage fonctionnant en circuit fermé.The mechanical fluid circulation device 5 consists of one or more suction and discharge pumps, such as hydraulic pumps and / or worm pumps, and / or diaphragm pumps, and / or centrifugal pumps, and / or single acting or double acting mechanical piston pumps. It is a pumping station operating in a closed circuit.
Cette ou ces pompes aspirent et refoulent un fluide hydraulique 6 et expulsent ce fluide vers des conduites forcées 7.This or these pumps suck and discharge a hydraulic fluid 6 and expel this fluid towards penstocks 7.
Grâce à ces conduites, le fluide parvient de manière continue et sous pression dans une turbomachine 8 telle que notamment un turbocompresseur, un turbogénérateur, ou encore un turboalternateur.Thanks to these pipes, the fluid is supplied continuously and under pressure in a turbomachine 8 such as in particular a turbocharger, a turbogenerator, or even a turbo-alternator.
Suivant une autre variante avantageuse de l'invention, l'effet des pompes est amplifié par des vérins hydrauliques ou pneumatiques.According to another advantageous variant of the invention, the effect of the pumps is amplified by hydraulic or pneumatic cylinders.
Le fluide aspiré et refoulé par les pompes 5 est un fluide spécial dont la composition chimique et la viscosité sont déterminées et constamment contrôlées. La composition chimique est contrôlée par des prélèvements et des analyses fréquentes. La viscosité est contrôlée en agissant sur la température du fluide. De préférence, le fluide est d'origine naturelle et biodégradable.The fluid sucked in and discharged by the pumps 5 is a special fluid whose chemical composition and viscosity are determined and constantly checked. The chemical composition is checked by frequent sampling and analysis. The viscosity is controlled by acting on the temperature of the fluid. Preferably, the fluid is of natural origin and biodegradable.
Un autre mode de réalisation du dispositif selon l'invention consiste à utiliser des turbomachines aussi bien pour comprimer le gaz que pour faire circuler le fluide ou l'éjecter vers le groupe turbine/alternateur.Another embodiment of the device according to the invention consists in using turbomachines as well for compressing the gas as for circulating the fluid or ejecting it towards the turbine / alternator group.
Suivant le dispositif selon l'invention, l'électricité produite est réutilisée pour l'alimentation des surpresseurs pneumatiques qui servent à comprimer le gaz.According to the device according to the invention, the electricity produced is reused to supply the pneumatic boosters which are used to compress the gas.
Dans le cas où le chauffage du gaz comprimé, en vue de son déstockage, est réalisé notamment au moyen d'une résistance électrique, cette résistance est alimentée avec l'énergie produite selon le procédé.In the case where the heating of the compressed gas, with a view to its destocking, is carried out in particular by means of an electrical resistance, this resistance is supplied with the energy produced according to the method.
Enfin l'énergie produite est également réutilisée pour l'alimentation de la turbomachine. Finally, the energy produced is also reused to supply the turbomachine.
