Description

-1- DISPOSITIF DE CONTROLE D'UNE INSTALLATION DE PRODUCTION D'ENERGIE ELECTRIQUE ET INSTALLATION DE PRODUCTION D'ENERGIE ELECTRIQUE METTANT EN OUVRE UN TEL DISPOSITIF DOMAINE DE L'INVENTION -1- DEVICE FOR CONTROLLING AN ELECTRIC POWER GENERATION PLANT AND ELECTRIC POWER GENERATING PLANT ENHANCING SUCH DEVICE DOMAIN OF THE INVENTION

L'invention se rapporte au domaine général de la production d'énergie électrique par le biais de panneaux ou modules photovoltaïques. De manière connue, de tels panneaux transforment l'énergie solaire en un courant électrique continu. The invention relates to the general field of the production of electrical energy by means of panels or photovoltaic modules. In known manner, such panels convert solar energy into a continuous electric current.

Elle concerne plus particulièrement une installation de production d'énergie électrique. De telles installations mettent en oeuvre comme générateur d'électricité de tels modules photovoltaïques, et intègrent en outre une ou plusieurs batteries, ou peuvent être également raccordées au réseau domestique via un convertisseur. ETAT ANTERIEUR DE LA TECHNIQUE It relates more particularly to an installation of electrical energy production. Such installations implement such photovoltaic modules as the electricity generator, and also integrate one or more batteries, or can also be connected to the home network via a converter. PRIOR STATE OF THE TECHNIQUE

La sensibilisation à la protection de la planète, outre la hausse régulière des énergies fossiles, a conduit depuis quelques années déjà au développement de solutions de 20 remplacement pour la production d'énergie dites renouvelables et notamment l'énergie solaire. Awareness of the protection of the planet, in addition to the steady rise in fossil fuels, has led for some years now to the development of replacement solutions for the production of so-called renewable energy and in particular solar energy.

Outre son caractère non polluant, l'énergie solaire s'avère tout particulièrement adaptée pour la production d'électricité en des lieux isolés, tels que des zones arides, 25 ou à faible densité de population, dans lesquels la distribution d'énergie électrique par voie traditionnelle, c'est à dire par le réseau domestique, s'avère d'un coût prohibitif. In addition to its non-polluting character, solar energy is particularly suitable for the production of electricity in isolated places, such as arid areas, or low population density, in which the distribution of electrical energy by traditional way, that is to say by the domestic network, proves to be prohibitively expensive.

L'intérêt de ce type d'installation de production d'énergie électrique ne se limite pas 30 à ces seules zones isolées. En effet, l'essor des énergies renouvelables a conduit à la mise en place de champs de modules photovoltaïques sur les toits des habitations. Dans ce cas, ladite installation est reliée au réseau d'alimentation électrique domestique. Ce couplage nécessite cependant des tensions élevées aux bornes du circuit électrique de ladite installation. Ce faisant, cette installation présente une 35 certaine dangerosité pour les personnels assurant sa mise en place et sa maintenance, en raison même du principe physique sous tendant la production d'énergie électrique. 15 2940548 -2- En effet, et par conception, les modules photovoltaïques constitutifs d'une telle installation produisent de l'électricité sous l'action du rayonnement solaire, cette production ne s'arrêtant pas nonobstant la coupure du circuit auquel les modules sont raccordés. Cette tension est d'autant plus élevée que le nombre de module est lui- 5 même élevé, voire même le nombre de branches de tels modules montées en parallèle les unes par rapport aux autres, constituant ainsi le champ photovoltaïque de l'installation. The interest of this type of power generation installation is not limited to these isolated areas alone. Indeed, the rise of renewable energies has led to the establishment of photovoltaic module fields on the roofs of homes. In this case, said installation is connected to the domestic power supply network. This coupling however requires high voltages across the electrical circuit of said installation. In doing so, this installation presents a certain danger to the personnel ensuring its installation and its maintenance, because of the physical principle underlying the production of electrical energy. As a matter of fact, and by design, the photovoltaic modules constituting such an installation produce electricity under the action of solar radiation, this production not stopping notwithstanding the interruption of the circuit to which the modules are connected. connected. This voltage is even higher than the number of modules is itself high, or even the number of branches of such modules connected in parallel with each other, thus constituting the photovoltaic field of the installation.

Cette dangerosité concerne également les personnels de secours, notamment les 10 pompiers, en cas d'incendie, susceptibles de devoir se déplacer ou d'intervenir au niveau du toit en question. This danger also concerns rescue personnel, in particular firefighters, in case of fire, who may have to move or intervene at the level of the roof in question.

Ainsi, la tension entre les deux bornes du circuit d'alimentation en énergie électrique de l'habitation considérée, lorsque cette énergie est produite par des modules photovoltaïques, dépasse facilement la valeur normative de 120 volts, constituant une limite de sécurité, pour atteindre plusieurs centaines de volts, soit une tension largement suffisante pour conduire à l'électrisation ou à l'électrocution du personnel en question. Thus, the voltage between the two terminals of the electrical energy supply circuit of the dwelling considered, when this energy is produced by photovoltaic modules, easily exceeds the normative value of 120 volts, constituting a safety limit, to reach several hundreds of volts, enough voltage to lead to the electrification or electrocution of the personnel in question.

Afin de pallier cette difficulté, on a proposé, par exemple dans le document FR 2 894 401, l'intégration d'un émetteur dans le circuit de l'installation de production d'énergie électrique, utilisant le courant porteur circulant dans ledit circuit pour envoyer de manière périodique un signal alternatif destiné à être capté par un capteur commandant un interrupteur monté en sortie des bornes de puissance de chacun des modules. In order to overcome this difficulty, it has been proposed, for example in document FR 2 894 401, the integration of a transmitter into the circuit of the electrical energy production installation, using the carrier current flowing in said circuit for periodically sending an alternating signal to be picked up by a sensor controlling a switch mounted at the output of the power terminals of each of the modules.

Si incontestablement, ce dispositif constitue un progrès par rapport aux installations de l'état antérieur de la technique, en revanche, l'expérience démontre que le circuit de puissance sur lequel est monté l'émetteur est lui-même susceptible d'être détruit notamment en cas d'incendie. Ce faisant, et dans une telle hypothèse, il n'est pas possible d'émettre le signal susceptible d'induire l'ouverture du ou des interrupteurs montés aux sorties des modules et partant, d'interrompre la production d'énergie électrique, de sorte que les mêmes dangers que ceux des dispositifs connus, notamment en termes de tension pour le personnel susceptible d'évoluer à ce niveau demeurent. On est en effet en mode sécurité positive, de sorte que même si les câbles de puissance sont coupés, les modules ou séries de modules demeurent sous tension. While undoubtedly, this device is an improvement over the installations of the prior art, however, experience shows that the power circuit on which the transmitter is mounted is itself likely to be destroyed including in case of fire. In doing so, and in such a case, it is not possible to emit the signal likely to induce the opening of the switch (s) mounted at the outputs of the modules and thus to interrupt the production of electrical energy, so that the same dangers as those of the known devices, especially in terms of tension for staff likely to evolve at this level remain. It is indeed in positive security mode, so that even if the power cables are cut, the modules or series of modules remain energized.

L'objet de l'invention est de s'affranchir de cet inconvénient. The object of the invention is to overcome this disadvantage.

EXPOSE DE L'INVENTION SUMMARY OF THE INVENTION

L'invention propose un dispositif de contrôle d'une installation de production d'énergie électrique comprenant une pluralité de modules photovoltaïques montés en série et/ou en parallèle et couplés à un circuit électrique d'alimentation d'une batterie de stockage d'électricité, ou d'alimentation d'un ou de plusieurs récepteurs, voire susceptibles d'être reliés au réseau d'alimentation électrique. The invention proposes a device for controlling an electrical energy production installation comprising a plurality of photovoltaic modules mounted in series and / or in parallel and coupled to an electric circuit for supplying an electric storage battery. , or supplying one or more receivers, or even likely to be connected to the power supply network.

Il se caractérise en ce qu'il comprend : ^ au moins un interrupteur actionnable par un circuit dédié commandé par un récepteur d'ondes radio, susceptible de placer en court-circuit les modules photovoltaïques ou les séries de modules photovoltaïques, ^ et un émetteur radio extérieur à l'installation, apte à émettre un signal susceptible d'être capté par ledit récepteur, ledit signal induisant la fermeture dudit interrupteur afin de placer les modules ou les séries de modules en court- circuit. It is characterized in that it comprises: at least one switch actuable by a dedicated circuit controlled by a radio wave receiver, capable of short-circuiting the photovoltaic modules or series of photovoltaic modules, and a transmitter radio external to the installation, able to emit a signal that can be picked up by said receiver, said signal inducing the closing of said switch in order to place the modules or series of modules short-circuited.

En d'autres termes, en suite de la fermeture du ou des interrupteurs, on place chacun des modules ou chacune des séries de modules en court-circuit, de sorte que la tension à leurs bornes devient nulle, réduisant à néant tout danger d'électrocution du personnel susceptible d'évoluer au niveau de ladite installation, quand bien même lesdits modules sont toujours soumis à rayonnement solaire. In other words, following the closing of the switch (s), each of the modules or each series of modules is placed in short-circuit, so that the voltage at their terminals becomes zero, reducing to zero any danger of electrocution personnel likely to evolve at said installation, even though said modules are still subject to solar radiation.

Selon une première version de l'invention, chacun des modules est muni d'un interrupteur en question monté en parallèle à ses bornes. Le circuit d'actionnement associé à chacun desdits interrupteurs est muni du même récepteur d'onde radio, l'ensemble desdits récepteurs fonctionnant selon la même fréquence radio que celle de l'émetteur extérieur, de sorte que l'actionnement de ce dernier engendre la fermeture simultanée de tous les interrupteurs au niveau de chacun des modules. According to a first version of the invention, each of the modules is provided with a switch in question mounted in parallel at its terminals. The actuation circuit associated with each of said switches is provided with the same radio wave receiver, all of said receivers operating at the same radio frequency as that of the external transmitter, so that the actuation of the latter generates the simultaneous closing of all the switches at each of the modules.

Selon une autre variante de l'invention, les modules photovoltaïques sont montés en séries de plusieurs modules, lesdites séries étant elles-mêmes montées en parallèle les unes par rapport aux autres et, l'interrupteur caractéristique est lui-même monté en parallèle aux bornes de ces séries. Dans cette variante, l'installation ne comporte donc qu'un seul interrupteur qui, lorsqu'il est actionné par l'émetteur extérieur, engendre la mise en court circuit du circuit de puissance alimenté par les séries de modules photovoltaïques. -3- 2940548 -4- Selon une version avantageuse de l'invention, le circuit associé à chaque interrupteur comporte également un émetteur radio, apte à engendrer un signal radio de confirmation de la bonne réception et de la bonne application de la consigne, susceptible d'être capté par un indicateur, visuel notamment, extérieur à 5 l'installation, muni d'un récepteur approprié, permettant ainsi d'assurer le contrôle effectif pour le personnel susceptible d'intervenir. According to another variant of the invention, the photovoltaic modules are mounted in series of several modules, said series being themselves connected in parallel with each other and the characteristic switch is itself connected in parallel to the terminals. of these series. In this variant, the installation therefore comprises only one switch which, when actuated by the external transmitter, causes the short circuit of the power circuit supplied by the series of photovoltaic modules. According to an advantageous version of the invention, the circuit associated with each switch also comprises a radio transmitter, capable of generating a radio signal confirming the good reception and the correct application of the setpoint, capable of to be captured by an indicator, visual including outside the facility, provided with a suitable receiver, thus ensuring effective control for personnel likely to intervene.

BREVE DESCRIPTION DES FIGURES BRIEF DESCRIPTION OF THE FIGURES

10 La manière dont l'invention peut être réalisée et les avantages qui en découlent, ressortiront mieux des exemples de réalisation qui suivent, donnés à titre indicatif et non limitatifs à l'appui des figures annexées. The manner in which the invention can be realized and the advantages which result therefrom will emerge more clearly from the following exemplary embodiments, given by way of non-limiting indication, in support of the appended figures.

La figure 1 est une représentation schématique d'un circuit selon une première forme 15 de réalisation de l'invention dans laquelle l'installation de production d'énergie électrique est couplée au réseau d'alimentation domestique. La figure 2 est une vue analogue à la figure 1, mais illustrant une autre forme de réalisation de l'invention. Figure 1 is a schematic representation of a circuit according to a first embodiment of the invention in which the power generation plant is coupled to the domestic power supply network. Figure 2 is a view similar to Figure 1, but illustrating another embodiment of the invention.

20 DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION

La figure 1 illustre donc une première forme de réalisation du dispositif conforme à l'invention. Le schéma représenté concerne une installation de production d'énergie électrique par la mise en oeuvre de modules photovoltaïques. Cette installation est, en 25 l'espèce, destinée à être couplée au réseau d'alimentation domestique, étant cependant entendu qu'une telle installation pourrait être raccordée à un récepteur électrique ou à une batterie d'accumulateurs via des protections adéquates du type fusibles ou disjoncteur. FIG. 1 thus illustrates a first embodiment of the device according to the invention. The diagram shown relates to an installation for producing electrical energy by the implementation of photovoltaic modules. This installation is, in this case, intended to be coupled to the domestic supply network, it being understood, however, that such an installation could be connected to an electric receiver or to a storage battery via adequate fuse-type protections. or circuit breaker.

30 Cette installation comprend fondamentalement un certain nombre de générateurs d'énergie électrique (2), montés en série, la figure 1 illustrant en l'espèce trois séries (10, 11, 12) de tels générateurs montées en parallèle. This installation basically comprises a certain number of electric power generators (2), connected in series, FIG. 1 illustrating in this case three series (10, 11, 12) of such generators connected in parallel.

Chacun de ces générateurs (2) est constitué d'un module (3) d'énergie 35 photovoltaïque. Un tel module est en soi connu pour la transformation du rayonnement solaire en courant électrique continu. 2940548 -5- Ces séries sont montées sur un circuit de puissance (1) fermé notamment sur un onduleur ou convertisseur (6), destiné, de manière connue, à transformer le courant continu produit par les modules photovoltaïques (3) en un courant alternatif afin de permettre son raccordement au réseau domestique (9). 5 Selon une caractéristique fondamentale de l'invention, les deux branches du circuit de puissance (1) sont en outre susceptibles d'être court-circuitées par une branche conductrice (15) associée à un interrupteur (4). Plus précisément, cet interrupteur (4) est donc susceptible de fermer la branche (15) et donc de mettre en court-circuit les 10 deux branches du circuit de puissance (1), conduisant à générer une tension nulle aux bornes des différentes séries (10), (11) et (12) de modules photovoltaïques. Each of these generators (2) consists of a module (3) of photovoltaic energy. Such a module is in itself known for the transformation of solar radiation into direct electric current. These series are mounted on a closed power circuit (1), in particular on an inverter or converter (6), intended, in known manner, to convert the direct current produced by the photovoltaic modules (3) into an alternating current. to allow connection to the home network (9). According to a fundamental characteristic of the invention, the two branches of the power circuit (1) are furthermore capable of being short-circuited by a conductive branch (15) associated with a switch (4). More precisely, this switch (4) is thus capable of closing the branch (15) and thus of shorting the two branches of the power circuit (1), leading to generating a zero voltage across the different series ( 10), (11) and (12) of photovoltaic modules.

Selon l'invention, cet interrupteur (4) est fermé par un circuit électrique intégré dans un boitier (7) après réception d'un signal radio transmis par un émetteur (8) externe à 15 l'installation, et réceptionné par un récepteur (5) associé au circuit électrique (7) de l'interrupteur (4). According to the invention, this switch (4) is closed by an electric circuit integrated in a box (7) after receiving a radio signal transmitted by a transmitter (8) external to the installation, and received by a receiver ( 5) associated with the electrical circuit (7) of the switch (4).

En d'autres termes, sur injonction d'un utilisateur, et par exemple du personnel de sécurité ou de pompiers, on induit par simple émission d'un signal radio par le biais 20 d'un émetteur (8) la mise hors tension du circuit de puissance (1) par fermeture de l'interrupteur (4). In other words, at the request of a user, and for example security personnel or firefighters, a radio signal is simply transmitted by means of a transmitter (8) and the power is turned off. power circuit (1) by closing the switch (4).

Cet interrupteur est par exemple de nature électronique par exemple un transistor à effet de champ MOSFET ou un thyristor, mais peut également être de nature 25 mécanique, du type relais ou disjoncteur. This switch is for example electronic in nature, for example a MOSFET field effect transistor or a thyristor, but can also be of a mechanical nature, of the relay or circuit breaker type.

Selon une variante de réalisation de l'invention représentée en relation avec la figure 2, chacun des modules photovoltaïques (3) comporte une branche parallèle intégrant un interrupteur (13) susceptible, lorsque celui-ci est fermé, de mettre en court-circuit 30 ledit module photovoltaïque (3) et corollairement de générer une tension nulle à ses bornes, quand bien même ledit module est soumis au rayonnement solaire. A l'instar de l'interrupteur (4), chacun des interrupteurs (13) est commandé par un circuit électrique actionné par un signal radio réceptionné par un émetteur (14) et transmis audit circuit. 35 2940548 -6- Dans ce cas de figure, l'intégralité des modules photovoltaïques (3) de l'installation est donc simultanément mise en court-circuit par l'émission du signal radio par le canal de l'émetteur (8). Cela suppose donc que l'intégralité des récepteurs (14) fonctionne sur la même fréquence radio. 5 Selon une variante avantageuse de l'invention, le circuit électrique associé à l'interrupteur (4) ou aux interrupteurs (13) mis en oeuvre est également susceptible de comprendre un émetteur radio (non représenté), destiné à émettre un signal radio au niveau d'un organe de restitution sensorielle, lumineux ou auditif (également non 10 représenté), placé hors de l'installation, et propre à matérialiser la bonne application de la consigne de fermeture du ou des interrupteurs considérés. According to an alternative embodiment of the invention shown in relation with FIG. 2, each of the photovoltaic modules (3) comprises a parallel branch integrating a switch (13) capable, when the latter is closed, of short-circuiting said photovoltaic module (3) and consequently to generate a zero voltage across its terminals, even when said module is subjected to solar radiation. Like the switch (4), each of the switches (13) is controlled by an electric circuit operated by a radio signal received by a transmitter (14) and transmitted to said circuit. In this case, the entire photovoltaic module (3) of the installation is thus simultaneously short-circuited by the transmission of the radio signal by the channel of the transmitter (8). This therefore assumes that all receivers (14) operate on the same radio frequency. According to an advantageous variant of the invention, the electric circuit associated with the switch (4) or with the switches (13) used may also comprise a radio transmitter (not shown), intended to emit a radio signal at level of a sensory, luminous or auditory restitution device (also not shown), placed outside the installation, and suitable for materializing the correct application of the closing instruction of the switch or switches considered.

Dans ces conditions, l'intervention de tout personnel, notamment de sécurité ou de maintenance, est sécurisée, puisqu'aussi bien, en raison de la tension nulle générée 15 aux bandes des séries de modules, il n'y a plus aucun risque d'électrocution quand bien même les bornes de sortie du circuit de puissance (1) raccordées au niveau de l'onduleur (6) pourraient être détruites notamment en raison d'un incendie. Under these conditions, the intervention of any personnel, in particular security or maintenance, is secure, since, because of the zero voltage generated on the strips of the series of modules, there is no longer any risk of damage. electrocution even if the output terminals of the power circuit (1) connected to the level of the inverter (6) could be destroyed in particular because of a fire.

On conçoit dès lors tout l'intérêt de l'invention notamment en termes de sécurisation 20 des intervenants. It is therefore conceivable that the interest of the invention particularly in terms of securing the speakers.
