Abstract
Description
La présente invention concerne un lampadaire comprenant un ensemble de cellules photovoltaïques, ainsi qu'un réseau de tels lampadaires. Un lampadaire comprend classiquement un mât se fixant dans le sol et une lanterne fixée à l'extrémité libre du mât et comprenant un dispositif lumineux. Des premiers câbles électriques souterrains sont reliés au réseau d'un fournisseur d'énergie, d'une part, et à chaque dispositif lumineux, d'autre part. Il existe des lampadaires comprenant un ensemble de cellules photovoltaïques permettant de capter l'énergie solaire et de la transformer en énergie électrique. L'énergie électrique est transportée via des deuxièmes câbles électriques souterrains vers un poste de comptage et de transformation avant d'être injectée dans le réseau du fournisseur d'énergie. Chaque lampadaire d'une zone est connecté sur les mêmes deuxièmes câbles qui peuvent courir sur de grandes distances avant d'atteindre le poste de comptage et de transformation. Les premiers câbles et le réseau du fournisseur d'énergie transportent un courant alternatif, tandis que les deuxièmes câbles transportent un courant continu. Les premiers câbles et le réseau du distributeur d'énergie sont constitués d'une paire de conducteurs, l'un supportant la phase et l'autre supportant le neutre. Les deuxièmes câbles sont également constitués d'une paire de conducteurs. Le poste de comptage et de transformation permet de transformer le courant continu en courant alternatif et de comptabiliser la quantité de courant alternatif injecté sur le réseau du fournisseur d'énergie. La grande longueur des deuxièmes câbles entraîne des pertes importantes sauf à utiliser des conducteurs à forte section ce qui est excessivement coûteux. Un tel réseau n'est pas viable du fait des coûts engendrés par son installation. En effet, il est nécessaire d'enterrer les premiers et les deuxièmes câbles et il est également nécessaire d'utiliser pour ces derniers des câbles à forte section. Un objet de la présente invention est de proposer un réseau de lampadaires qui ne présente pas les inconvénients de l'art antérieur et qui en particulier permet une mise en oeuvre aisée et peu onéreuse. The present invention relates to a lamp post comprising a set of photovoltaic cells, and a network of such streetlights. A floor lamp conventionally comprises a mast fixing in the ground and a lantern attached to the free end of the mast and comprising a light device. First underground electric cables are connected to the network of a power supplier, on the one hand, and to each light device, on the other hand. There are street lights including a set of photovoltaic cells to capture solar energy and transform it into electrical energy. The electrical energy is transported via second underground electrical cables to a metering and processing station before being injected into the energy supplier's network. Each lamppost in one zone is connected to the same second cables that can run over long distances before reaching the counting and transformation station. The first cables and the network of the energy supplier carry an alternating current, while the second cables carry a direct current. The first cables and the network of the energy distributor consist of a pair of conductors, one supporting the phase and the other supporting the neutral. The second cables also consist of a pair of conductors. The metering and transforming station converts direct current into alternating current and accounts for the amount of alternating current injected into the utility grid. The long length of the second cables causes significant losses except to use heavy section conductors which is excessively expensive. Such a network is not viable because of the costs incurred by its installation. Indeed, it is necessary to bury the first and second cables and it is also necessary to use for these cables with a large section. An object of the present invention is to provide a street lamp array which does not have the disadvantages of the prior art and which in particular allows easy and inexpensive implementation.
A cet effet, est proposé un lampadaire alimenté électriquement depuis un câble électrique, le lampadaire comprenant: - un mât se fixant dans le sol, - un dispositif lumineux fixé à l'extrémité libre du mât, - un ensemble de cellules photovoltaïques, et - un module de gestion d'énergie comprenant: - un onduleur et - un commutateur, l'onduleur transformant le courant électrique continu issu de l'ensemble de cellules photovoltaïques en un courant alternatif et le commutateur étant apte à prendre une première position dans laquelle le courant électrique issu de l'onduleur est envoyé sur le câble électrique et une deuxième position dans laquelle le courant provenant du câble électrique est envoyé vers le dispositif lumineux. Avantageusement, le lampadaire comprend un moyen de commande destiné à l0 changer la position du commutateur. Avantageusement, le moyen de commande comprend des moyens d'analyse d'une caractéristique du courant délivré par l'ensemble de cellules photovoltaïques et des moyens de comparaison de cette caractéristique à un seuil de déclenchement. Avantageusement, le seuil de déclenchement varie en fonction de la position du 15 commutateur. L'invention propose également un réseau de lampadaires comprenant: - un câble électrique, et - un ensemble de plusieurs lampadaires, chacun étant selon l'une des variantes précédentes.For this purpose, is proposed a lamp powered electrically from an electric cable, the lamp including: - a mast fixing in the ground, - a light device attached to the free end of the mast, - a set of photovoltaic cells, and - a power management module comprising: - an inverter and - a switch, the inverter transforming the direct electric current coming from the set of photovoltaic cells into an alternating current and the switch being able to take a first position in which the electrical current from the inverter is sent on the electric cable and a second position in which the current from the electric cable is sent to the light device. Advantageously, the street lamp comprises a control means for changing the position of the switch. Advantageously, the control means comprises means for analyzing a characteristic of the current delivered by the set of photovoltaic cells and means for comparing this characteristic to a trigger threshold. Advantageously, the triggering threshold varies according to the position of the switch. The invention also proposes a network of lampposts comprising: - an electric cable, and - a set of several street lamps, each being according to one of the preceding variants.
20 Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels : la Fig. 1 représente un réseau de lampadaires selon l'invention, et 25 la Fig. 2 est une représentation schématique d'un module de gestion d'énergie. La Fig. 1 montre un réseau 100 de lampadaires. Dans le mode de réalisation présenté ici, le réseau 100 comprend un câble électrique 114 et trois lampadaires 102a-c. Chaque lampadaire 102a-c comprend un mât 104 se fixant dans le sol, une lanterne 106 fixée à l'extrémité libre du mât 104 et comprenant un dispositif lumineux, 30 et un ensemble de cellules photovoltaïques 108. Chaque lampadaire 102a-c est alimenté électriquement à un réseau électrique 112 d'un fournisseur d'énergie via le câble électrique 114 classiquement constitué de deux conducteurs. Comme cela est expliqué ci-dessous, le câble électrique 114 transporte uniquement un courant alternatif. Entre le réseau du distributeur 112 et le câble électrique 114 est disposé un poste de comptage 116 qui comptabilise le courant qui provient du réseau du fournisseur 112 et le courant qui provient du câble électrique 114. Chaque lampadaire 102a-c comprend un module de gestion d'énergie 110 qui est 5 représenté sur la Fig. 2. Le module de gestion d'énergie 110 comprend un onduleur 202 et un commutateur 204. L'onduleur 202 est connecté à l'ensemble de cellules photovoltaïques 108 du lampadaire 102a-c et transforme le courant électrique continu issu de l'ensemble de cellules photovoltaïques 108 en courant alternatif. Le courant alternatif ainsi généré 10 est envoyé via le commutateur 204 sur le câble électrique 114, jusqu'au poste de comptage 116, puis jusqu'au réseau du distributeur 112. De par le positionnement d'un onduleur 202 sur chaque lampadaire 102a-c, la distance entre l'ensemble de cellules photovoltaïques 108 et l'onduleur 202 est réduite, d'où une réduction des pertes en courant continu et une réduction des sections des câbles.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being given in relation to the attached drawings, among which: Fig. 1 represents a network of lampposts according to the invention, and FIG. 2 is a schematic representation of a power management module. Fig. 1 shows a network 100 of lampposts. In the embodiment presented here, the network 100 comprises an electric cable 114 and three streetlights 102a-c. Each lamppost 102a-c comprises a mast 104 which is fixed in the ground, a lantern 106 fixed to the free end of the mast 104 and comprising a light device, and a set of photovoltaic cells 108. Each lamppost 102a-c is electrically powered. to an electricity network 112 of a power supplier via the electric cable 114 conventionally consisting of two conductors. As explained below, the electric cable 114 carries only alternating current. Between the network of the distributor 112 and the electric cable 114 is arranged a counting station 116 which counts the current that comes from the network of the supplier 112 and the current that comes from the electric cable 114. Each lamppost 102a-c includes a management module. energy 110 which is shown in FIG. 2. The energy management module 110 comprises an inverter 202 and a switch 204. The inverter 202 is connected to the set of photovoltaic cells 108 of the lamppost 102a-c and transforms the continuous electric current from the set of photovoltaic cells 108 AC. The alternating current thus generated 10 is sent via the switch 204 on the electric cable 114, up to the counting station 116, then to the network of the distributor 112. By the positioning of an inverter 202 on each lamppost 102a-c , the distance between the set of photovoltaic cells 108 and the inverter 202 is reduced, resulting in a reduction in DC losses and a reduction in cable cross-sections.
15 La mise en oeuvre d'un tel réseau 100 nécessite la mise en place d'un seul réseau de câbles électriques 114 et ceux-ci sont de section réduite car les pertes sont réduites du fait qu'ils transportent un courant alternatif. Le commutateur 204 est prévu pour pouvoir prendre une première position dans laquelle le courant électrique issu de l'onduleur 202 est envoyé sur le câble électrique 20 114 et une deuxième position dans laquelle le courant provenant du câble électrique 114 est envoyé vers le dispositif lumineux 206 de la lanterne 106. La première position correspond à une position jour et la deuxième position correspond à une position nuit. La commande du commutateur 204 s'effectue par exemple à distance depuis un 25 poste de commande. Dans un autre mode de réalisation, la commande du commutateur 204 peut s'effectuer automatiquement en fonction de la luminosité ambiante. A cette fin, le module de gestion d'énergie 110 comprend un moyen de commande 208 destiné à changer la position du commutateur 204.The implementation of such a network 100 requires the establishment of a single network of electric cables 114 and these are of reduced section because the losses are reduced because they carry an alternating current. The switch 204 is provided to be able to take a first position in which the electric current from the inverter 202 is sent on the electric cable 114 and a second position in which the current from the electric cable 114 is sent to the light device 206 lantern 106. The first position corresponds to a day position and the second position corresponds to a night position. The control of the switch 204 is effected for example remotely from a control station. In another embodiment, the control of the switch 204 can be performed automatically depending on the ambient brightness. For this purpose, the power management module 110 includes a control means 208 for changing the position of the switch 204.
30 Le moyen de commande 208 comprend des moyens d'analyse d'une caractéristique du courant délivré par l'ensemble de cellules photovoltaïques 108 et des moyens de comparaison de cette caractéristique à un seuil de déclenchement. La caractéristique ainsi relevée et analysée est comparée au seuil de déclenchement. La valeur du seuil de déclenchement peut varier en fonction de la position du commutateur 204 au moment de l'analyse. Cette caractéristique peut être par exemple l'intensité ou la tension. Lorsque le seuil de déclenchement est atteint, le moyen de commande 208 commande le changement de position du commutateur 204. Par exemple, lorsque le commutateur 204 est en position jour et lorsque l'intensité du courant électrique délivré par l'ensemble de cellules photovoltaïques 108 passe sous un seuil inférieur de déclenchement, le moyen de commande 208 commande le passage du commutateur 204 en position nuit. Lorsque le commutateur 204 est en position nuit et lorsque l'intensité du courant électrique délivré par l'ensemble de cellules photovoltaïques 108 passe au-dessus d'un seuil supérieur de déclenchement, le moyen de commande 208 commande le passage du commutateur 204 en position jour. La valeur du seuil inférieur et la valeur du seuil supérieur peuvent être différentes. Cette mise en oeuvre particulière permet de commander individuellement chaque lampadaire 102a-c du réseau 100, et en fonction de l'ensoleillement local, chaque lampadaire 102a-c peut être soit en position jour, soit en position nuit et ceci indépendamment de la position des autres lampadaires du réseau 100, ce qui permet d'optimiser la production d'énergie électrique par les ensembles de cellules photovoltaïques 108, d'une part, et la consommation d'énergie électrique par les dispositif lumineux 206, d'autre part. Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art. The control means 208 comprises means for analyzing a characteristic of the current delivered by the set of photovoltaic cells 108 and means for comparing this characteristic to a trigger threshold. The characteristic thus noted and analyzed is compared to the triggering threshold. The value of the trip threshold may vary depending on the position of the switch 204 at the time of analysis. This characteristic can be, for example, the intensity or the voltage. When the triggering threshold is reached, the control means 208 controls the change of position of the switch 204. For example, when the switch 204 is in the day position and when the intensity of the electric current delivered by the set of photovoltaic cells 108 passes under a lower trigger threshold, the control means 208 controls the passage of the switch 204 in the night position. When the switch 204 is in the night position and when the intensity of the electric current delivered by the set of photovoltaic cells 108 passes over a higher trigger threshold, the control means 208 controls the passage of the switch 204 in position day. The value of the lower threshold and the value of the upper threshold may be different. This particular implementation makes it possible to individually control each lamppost 102a-c of the network 100, and depending on the local irradiation, each lamppost 102a-c can be either in the day position or in the night position and this independently of the position of the other streetlights of the network 100, which optimizes the production of electrical energy by the sets of photovoltaic cells 108, on the one hand, and the consumption of electrical energy by the light device 206, on the other hand. Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art.
