Description

Appareil de mesure détaillée de consommation électrique Detailed meter of electrical consumption
11
La présente invention concerne un appareil de mesure détaillé de consommation électrique.The present invention relates to a detailed measuring device for electrical consumption.
Les mesures de consommations électriques sont effectuées classiquement au moyen de wattmètres ou compteurs d'énergie qui mesurent les tensions et courants d'alimentation des appareils, pour en déduire les valeurs de puissance et d'énergie consommées.The measurements of electrical consumption are carried out conventionally by means of power meters or energy meters which measure the voltages and currents of supply of the appliances, to deduce the values of power and energy consumed.
Les compteurs d'énergie les plus courants sont ceux utilisés pour la facturation des abonnés au réseau de distribution publique. Ils sont soit de type électromécanique - c'est-à-dire comprenant un moteur entraînant un disque gradué, dont la vitesse de rotation est proportionnelle à la puissance active consommée -, soit électroniques.The most common energy meters are those used for billing subscribers to the public distribution network. They are either electromechanical type - that is to say comprising a motor driving a graduated disc whose rotational speed is proportional to the active power consumed - or electronic.
Les compteurs d'énergie sont également nécessaires pour réaliser des mesures détaillées, par exemple pour connaître les consommations de chacun des départs d'un tableau électrique de répartition, c'est-à-dire pour connaître par exemple la consommation électrique des différents appareils électriques d'une maison d'habitation, d'un immeuble ou de locaux tertiaires. On parle alors de sous-comptage.Energy meters are also needed to carry out detailed measurements, for example to know the consumption of each of the departures of an electrical distribution board, that is to say to know for example the power consumption of the various electrical appliances. a dwelling house, a building or tertiary premises. This is called under-counting.
Les sous-comptages sont jusqu'à présent réalisés au moyen de multiples compteurs d'énergie classiques 1 , chacun relié à un départ de courant 2 particulier du tableau électrique, et nécessitant chacun des raccordements électriques 3 dédiés aux mesures de tension et de courant du départ auquel il est connecté. Une telle installation de mesure est représentée à la figure 1. Son désavantage majeur est qu'elle nécessite un câblage important pour les tensions et vers la centrale de calcul de consommation 4, câblage long à mettre en place, et coûteux.The sub-counts have heretofore been achieved by means of multiple conventional energy meters 1, each connected to a particular current 2 of the electrical switchboard, and each requiring electrical connections 3 dedicated to the voltage and current measurements of the switchgear. where it is connected. Such a measurement installation is represented in FIG. 1. Its major disadvantage is that it requires a large wiring for the voltages and towards the consumption calculation unit 4, long wiring to be put in place, and expensive.
A la figure 1 , on remarquera que pour les mesures de courant, on a représenté les capteurs de courant par des cercles pour schématiser le tore du capteur qui entoure le fil conducteur à mesurer, mais n'est pas en contact électrique direct avec lui. Or les tensions mesurées par les différents compteurs d'énergie, au niveau des différents départs, sont souvent les mêmes, car il s'agit des tensions fournies par le réseau électrique monophasé, bi- ou triphasé.In FIG. 1, it will be noted that, for current measurements, the current sensors are represented by circles to schematize the toroid of the sensor which surrounds the conductor wire to be measured, but is not in direct electrical contact with it. However, the voltages measured by the various energy meters, at the different feeders, are often the same, because they are the voltages supplied by the single-phase, two- or three-phase electrical network.
Il est donc possible de ne mesurer qu'en un seul point ces tensions, et les communiquer aux autres compteurs d'énergie, reliés à chaque départ de courant du tableau électrique. Les réseaux concernés étant généralement alternatifs à 50 ou 60 Hz, les valeurs de tension de chaque phase doivent cependant être mesurées et transmises plusieurs milliers de fois par seconde pour permettre des calculs précis de puissance.It is therefore possible to measure these voltages only in one point, and to communicate them to the other energy meters, connected to each current start of the electrical panel. As the networks concerned are generally alternating at 50 or 60 Hz, the voltage values of each However, the phase must be measured and transmitted several thousand times per second to allow accurate power calculations.
Dès lors, seule la mesure de courant est nécessaire, et l'on simplifie le câblage correspondant. Un dispositif de mesure de consommation électrique utilisant ce principe de simplification par mesure d'une tension unique, commune pour tous les départs d'un tableau électrique, est décrit dans la demande de brevet japonais JP 2001-298 877.Therefore, only the measurement of current is necessary, and one simplifies the corresponding wiring. An electrical consumption measuring device using this principle of simplification by measuring a single voltage common to all the starts of an electrical panel is described in Japanese Patent Application JP 2001-298 877.
Plus précisément, le dispositif de mesure décrit dans cette demande de brevet japonais, comprend des liaisons filaires analogiques permettant la mesure des intensités consommées sur chaque départ du tableau électrique, ces mesures étant transmises ensuite à une centrale de collecte desdites mesures, qui réalise un calcul de la puissance consommée et de l'énergie consommées par fil de départ, à partir des mesures de courant pour chaque fil correspondant.More specifically, the measuring device described in this Japanese patent application, includes analog wire links for measuring the intensities consumed on each start of the electrical panel, these measurements being then transmitted to a central collection of said measurements, which carries out a calculation the power consumed and the energy consumed by the starting wire, from the current measurements for each corresponding wire.
Une ligne unique fournit quant à elle la tension commune à tous les points de mesure, c'est-à-dire à tous les départs du tableau.A single line provides the voltage common to all measurement points, that is to say, all departures of the table.
Si un tel dispositif permet de résoudre les désavantages des dispositifs existants, notamment en termes de complexité du câblage mis en œuvre pour la mesure (qui est simplifié dans le dispositif décrit dans JP2001- 298 877), il n'en comporte pas moins au moins deux inconvénients majeurs.If such a device makes it possible to solve the disadvantages of the existing devices, in particular in terms of the complexity of the wiring used for the measurement (which is simplified in the device described in JP2001-298 877), it includes not less than two major disadvantages.
On a remarqué qu'avec un tel dispositif, un phénomène de parasitage important affecte les valeurs des mesures de courant transmises depuis chaque départ du tableau, vers la centrale de collecte des mesures. Ceci est dû à la longueur des liaisons analogiques et des signaux de faible amplitude délivrés par les capteurs de courant classiques.It has been noticed that with such a device, a significant interference phenomenon affects the values of the current measurements transmitted from each start of the array to the measurement collection center. This is due to the length of analog links and low amplitude signals delivered by conventional current sensors.
: En outre, le dispositif est conçu pour la mesure d'un nombre déterminé de capteurs de courant. Ce nombre ne peut dépasser quelques dizaines, sans quoi les liaisons vers les capteurs de courant deviennent trop longues et difficiles à mettre en œuvre.In addition, the device is designed for measuring a determined number of current sensors. This number can not exceed a few tens, otherwise the links to the current sensors become too long and difficult to implement.
Le problème technique sous-jacent à la présente invention, est donc.de fournir un dispositif de mesure détaillée des puissances et énergies consornmées sur départ d'un tableau électrique, qui soit à la fois très simple au niveau du câblage, et qui permette de s'affranchir des phénomènes de parasitage des mesures, dues à la présence même de l'installation électrique. Le problème technique cité ci-dessus, trouve une solution avec la présente invention, sous la forme d'un dispositif de mesure détaillée de la puissance et/ou de l'énergie consommée à travers au moins un départ d'un tableau électrique comprenant plusieurs départs, et raccordé à un réseau électrique monophasé, biphasé ou triphasé, ledit dispositif comprenant :The technical problem underlying the present invention, therefore, is to provide a device for measuring the power and energy consumption on the basis of an electrical panel, which is both very simple at the level of the wiring, and which makes it possible to to overcome the interference phenomena measures, due to the very presence of the electrical installation. The technical problem cited above finds a solution with the present invention, in the form of a device for the detailed measurement of the power and / or energy consumed through at least one start of an electrical panel comprising several outlets, and connected to a single-phase, two-phase or three-phase electrical network, said device comprising:
- une centrale de collecte de mesures commune aux différents départs électriques du tableau,a central collection of measurements common to the different electrical outputs of the board,
- un faisceau de fils de mesure de tension reliant la centrale de collecte aux câbles d'un départ électrique du tableau, le câble de chaque phase du départ étant relié à un fil de mesure de Ia tension correspondante, eta bundle of voltage measuring wires connecting the collection unit to the cables of an electrical feeder of the switchboard, the cable of each phase of the feeder being connected to a measuring wire of the corresponding voltage, and
- au moins un faisceau de fils munis de capteurs de courant reliant la centrale de collecte aux câbles électriques de chaque départ électrique mesuré, chaque câble du départ étant muni d'un capteur de mesure, caractérisé en ce que les fils des capteurs de courant du faisceau relié à chaque départ du tableau, sont regroupés et connectés à au moins un module de calcul numérique relié à la centrale de collecte par l'intermédiaire d'une liaison numérique commune à tous les modules de calcul, ladite liaison numérique permettant la transmission en temps réel des valeurs de tensions des phases mesurées depuis la centrale de collecte vers les modules de mesure, pour permettre le calcul par chacun de ces derniers des valeurs de puissance et/ou d'énergie consommées sur chaque départ correspondant, à partir des valeurs de courant mesurées localement et des valeurs de tension reçues par la liaison numérique.at least one bundle of wires provided with current sensors connecting the central collection unit to the electric cables of each measured electrical outlet, each cable of the outlet being provided with a measurement sensor, characterized in that the wires of the current sensors of the beam connected to each start of the array, are grouped together and connected to at least one digital calculation module connected to the collection unit via a digital link common to all the calculation modules, said digital link allowing the transmission in real time phase voltage values measured from the collection center to the measurement modules, to allow the calculation by each of the power values and / or energy consumed on each corresponding start, from the values of current measured locally and voltage values received by the digital link.
Par liaison numérique, on entend un câble ou tout autre moyen permettant la transmission de données numérisées entre les deux extrémités dudit fil.Digital link means a cable or any other means for transmitting digitized data between the two ends of said wire.
Avantageusement, la liaison numérique permet en outre la transmission depuis chaque module vers la centrale de collecte, des valeurs calculées de puissance et/ou d'énergie consommée(s) sur le départ correspondant.Advantageously, the digital link also allows the transmission from each module to the central collection, calculated power and / or energy values consumed (s) on the corresponding departure.
Selon une première variante d'exécution de l'invention, cette liaison numérique comprend un fil de bus métallique classique, du type de ceux utilisés dans les ordinateurs.According to a first variant embodiment of the invention, this digital link comprises a conventional metal bus wire of the type used in computers.
Selon une seconde variante, alternative de l'invention, cette liaison numérique comprend un fil de bus constitué d'une, ou plusieurs, fibre(s) optique(s), permettant la transmission des données de mesure sous forme numérique, par impulsions lumineuses. Un tel dispositif de transport d'informations numérisées par fibres optiques ne sera pas décrit plus avant dans le cadre de la présente description, puisqu'il est par ailleurs déjà utilisé dans d'autres domaines techniques. Selon une troisième variante d'exécution de l'invention, la liaison numérique comprend une liaison hertzienne, plus précisément une liaison par ondes hertziennes modulées.According to a second alternative variant of the invention, this digital link comprises a bus wire consisting of one or more optical fibers enabling the transmission of measurement data in the form of digital, by light pulses. Such an optical fiber scanned information transport device will not be described further in the context of the present description, since it is also already used in other technical fields. According to a third variant embodiment of the invention, the digital link comprises a radio link, more specifically a modulated radio link.
Avantageusement, la centrale de collecte est en outre reliée à des moyens de transmission à distance des mesures instantanées et des mesures enregistrées par chaque module de calcul. En effet, on aura compris que les modules de calcul ne permettent pas seulement de calculer la puissance et/ou l'énergie sur chaque départ du tableau électrique, mais également chaque module possède une mémoire qui lui permet de stocker un certain nombre de valeurs de puissance et/ou d'énergie calculées sur les périodes de temps précédentes, et éventuellement de les restituer vers la centrale de collecte sous une forme de valeurs numériques.Advantageously, the collection center is further connected to means for remote transmission of the instantaneous measurements and the measurements recorded by each calculation module. Indeed, it will be understood that the calculation modules do not only allow to calculate the power and / or energy on each start of the electrical panel, but also each module has a memory that allows it to store a number of values of power and / or energy calculated over the previous periods of time, and possibly to return them to the central collection in the form of numerical values.
De préférence, les moyens de transmission comprennent un module de radiotéléphonie à la norme GSM. Ceci permet à un électricien muni d'un téléphone GSM, de récupérer des données du dispositif de mesure, sans avoir à se déplacer sur le lieu où ce compteur est installé. Il peut également visualiser immédiatement l'effet de la mise en marche d'un appareil électrique sur les puissances appelées par les différents départs mesurés, tout en se déplaçant dans le bâtiment.Preferably, the transmission means comprise a GSM radio module. This allows an electrician with a GSM phone to retrieve data from the measuring device, without having to move to the place where this meter is installed. It can also immediately see the effect of starting an electrical device on the powers called by the different measured starts, while moving in the building.
Afin d'obtenir une bonne précision des mesures, la fréquence de transmission des mesures des tensions depuis la centrale de collecte (5) vers chaque module (9), est supérieure à 4000 Hz, c'est-à-dire que plus de 4.103 échantillons de tension de chaque phase mesurée sont transmis chaque seconde de la centrale de collecte vers les modules de calcul. Ces échantillons peuvent avantageusement être datés, permettant ainsi une interpolation par les modules de calcul, pour synchroniser au mieux les mesures de tension et de courant. Un bus de terrain répondant à la norme BOSCH CAN 1.2 remplit avantageusement ces fonctions.In order to obtain a good accuracy of the measurements, the transmission frequency of the measurements of the voltages from the collection unit (5) to each module (9) is greater than 4000 Hz, that is to say that more than 4.10 3 voltage samples of each measured phase are transmitted every second from the collection center to the calculation modules. These samples can advantageously be dated, thus allowing interpolation by the calculation modules, to synchronize the voltage and current measurements as well as possible. A fieldbus meeting the BOSCH CAN 1.2 standard performs these functions advantageously.
Selon nue variante possible d'exécution de l'invention, les mesures des tensions sont transmises par la centrale de collecte aux modules sous forme d'un ensemble de données numériques permettant aux modules de reconstituer les mesures de tension initiales. L'invention va à présent être décrite plus en détail à l'aide du dessin schématique annexé, qui représente à titre d'exemple non limitatif, une forme d'exécution préférée d'un dispositif de mesure de consommation électrique selon l'invention.According to nue possible variant embodiment of the invention, the voltages measurements are transmitted by the collection center to the modules in the form of a set of digital data allowing the modules to reconstruct the initial voltage measurements. The invention will now be described in more detail with the aid of the attached schematic drawing, which represents by way of nonlimiting example, a preferred embodiment of an electrical consumption measuring device according to the invention.

Le fil de bus permet la transmission, au format numérique, c'est-à- dire comme les données transmises à l'intérieur d'un ordinateur -, depuis la centrale de collecte 5 vers chaque module de mesure 9, des valeurs des tensions mesurées, et la transmission, le cas échéant, depuis chaque module 9 vers la centrale de collecte 5, des valeurs correspondantes de puissance et/ou d'énergie consommée(s) sur le départ 2 correspondant, calculées par ledit module à partir des valeurs de courant mesurées sur ledit départ et de la tension transmise sur le bus. La centrale de collecte 5 est équipée d'une interface utilisateur permettant la configuration du système de mesure et en particulier de sélectionner pour chaque capteur de courant de chaque module de calcul 9, la tension mesurée par la centrale de collecte qui sera utilisée pour le calcul de puissance et d'énergie. L'interface permet en outre la visualisation en temps réel des calculs de puissance et d'énergie de tous les départs mesurés du tableau électrique de répartition.The bus wire allows the transmission, in digital format, that is to say as the data transmitted inside a computer - from the collection unit 5 to each measurement module 9, the values of the voltages measured, and the transmission, if any, from each module 9 to the central collection 5, the corresponding values of power and / or energy consumed (s) on the corresponding 2 departure, calculated by said module from the values current measured on said start and the voltage transmitted on the bus.
