Abstract

Discriminator filter intended to be connected up between the electrical current supply network and an installation supplied by the said network and provided with means of remote control of its appliances through the current supply conductors, characterised in that all the branches of the filter and in particular the branches (L11, R11, C11, L21, C21, R21) situated at its two ends consist of damped resonance circuits whose tuning frequencies differ.

Description

La présente invention est relative aux filtres et se rapporte plus particulièrement aux filtres réjecteurs de courants porteurs destinés à être employés dans les installations de gestion de 1 éner gie utilisant le réseau électrique interne à une habitation. The present invention relates to filters and relates more particularly to filters for rejecting carrier currents intended for use in energy management installations using the internal electrical network of a dwelling.

Un émetteur placé sur le réseau à lînté- rieur de 1 installation, envoie des signaux codés de fréquence élevée par rapport aux 50 Hz du secteur, que chaque appareil branché sur le secteur est à même de détecter et d interpréter comme étant un signal de commande de mise en route ou non ou tout autre signal codé (point de consigne de régulation par exemple), à 1 aide d un récepteur décodeur. A transmitter placed on the network inside 1 installation sends coded signals of high frequency compared to the 50 Hz of the sector, which each device connected to the sector is able to detect and interpret as being a control signal start-up or not or any other coded signal (regulation setpoint for example), using a decoder receiver.

Un tel système de commande permet de réaliser des gains en énergie considérables et il semble pour cette raison devoir se développer dans un proche avenir. Such a control system allows considerable energy savings to be made and it therefore seems likely to develop in the near future.

L'utilisation des fils du secteur permet de réaliser une économie en matière d'installation électrique. The use of sector wires saves on electrical installation.

Cependant, il est nécessaire de disposer d'un filtre qui tout en laissant passer l'énergie électrique à 50 Hz destinée à 1 alimentation des appareils d'une installation, arrête les courants porteurs utilisés pour la télécommande des appareils de cette installation afin d'éviter que ces memes courants ne puissent en circulant sur le réseau perturber des installations voisines. However, it is necessary to have a filter which, while allowing electrical energy to pass at 50 Hz intended for supplying the devices of an installation, stops the carrier currents used for the remote control of the devices of this installation in order to prevent these same currents from being able to disturb neighboring installations by circulating on the network.

Or, les matériels existants sont d'un coût et d'un encombrement tels qu'ils condamnent l'emploi de cette technique de transmission à des fins de gestion de 1 énergie, surtout dans le secteur domestique. However, existing equipment is so costly and bulky that it condemns the use of this transmission technique for energy management purposes, especially in the domestic sector.

L invention vise donc à créer un filtre discriminateur qui permette de résoudre le problème énoncé ci-dessus. The invention therefore aims to create a discriminating filter which makes it possible to solve the problem stated above.

Elle a donc pour objet un filtre discriminateur destiné à être branché entre le réseau d alimentation en courant électrique et une installation alimentée par ledit réseau et pourvue de moyens de télécommande de ses appareils par les conducteurs d ali- mentationen courant. caractérisé en ce que toutes les branches du filtre et en particulier les branches situées aux deux extrémités de celui-ci sont constituées par des circuits résdnnants amortis dont les fréquences d'accord sont différentes. It therefore relates to a discriminating filter intended to be connected between the electric power supply network and an installation supplied by said network and provided with means for remote control of its devices by the current supply conductors. characterized in that all the branches of the filter and in particular the branches located at the two ends of the latter are constituted by damped resdnnant circuits whose tuning frequencies are different.

L'invention sera mieux comprise à la lecture de la description qui va suivre, faite en référence aux dessins annexés, donnés uniquement à titre d exemple et sur lesquels
- la Fig.1 est un schéma montrant des installations télécommandées par les conducteurs du réseau d alimentation équipées de filtres suivant l'in- vention;
- la Fig.2 est une vue schématique d'un filtre discriminateur suivant l'invention.The invention will be better understood on reading the description which follows, given with reference to the accompanying drawings, given solely by way of example and in which
- Fig.1 is a diagram showing installations remotely controlled by the conductors of the supply network equipped with filters according to the invention;
- Fig.2 is a schematic view of a discriminator filter according to the invention.

Sur la Fiv.1, on a représenté deux installations A et B alimentées chacune par le réseau. On Fiv. 1, two installations A and B are shown, each supplied by the network.

L'installation électrique A comporte des appareils électriques 1 télécommandables. The electrical installation A comprises remote-controlled electrical devices 1.

A cet effet, chaque appareil électrique 1 est pourvu d'un récepteur de télécommande 2 connecté par les conducteurs d'alimentation de l'appareil correspondant à un émetteur 3. To this end, each electrical appliance 1 is provided with a remote control receiver 2 connected by the supply conductors of the appliance corresponding to a transmitter 3.

Sur les conducteurs 4 de liaison de l'ins- tallation avec le réseau en aval du compteur 5 est disposé un filtre discriminateur 6 suivant l'invention.  On the conductors 4 connecting the installation with the network downstream of the counter 5 is arranged a discriminator filter 6 according to the invention.

L'installation électrique B est agencée de la même maniére que l'installation A et ses constituants portent donc les mêmes numéros de référence. The electrical installation B is arranged in the same way as the installation A and its components therefore bear the same reference numbers.

Le filtre discriminateur suivant 1' inven- tion va maintenant etre decrit en référence à la
Fig.2.The discriminating filter according to the invention will now be described with reference to the
Fig. 2.

L'originalité de ce filtre réside dans le fait qu'il doit conserver ses caractéristiques d'atténuation sans altération lorsque les impédances bran chées aux deux extrémités (composantes résistives et réactives) varient considérablement, soit en fonction de la nature de la charge branchée par l'abonné, soit en fonction de la configuration géométrique du réseau basse tension de distribution. The originality of this filter lies in the fact that it must retain its attenuation characteristics without alteration when the impedances connected to the two ends (resistive and reactive components) vary considerably, either according to the nature of the load connected by the subscriber, either according to the geometric configuration of the low-voltage distribution network.

De plus, ce filtre doit supporter le passage d un courant à 50 Hz important sans que son fonctionnement n'en soit perturbé. In addition, this filter must withstand the passage of a large 50 Hz current without affecting its operation.

Le filtre représenté à la Fig.2 comporte plusieurs cellules 8 à 10 formées chacune d'un circuit à résonance parallèle et d'un circuit à résonance série. The filter shown in Fig.2 has several cells 8 to 10 each formed of a parallel resonance circuit and a series resonance circuit.

Chaque circuit à résonance parallèle comprend une inductance L11, L12 ... L1n, une capacité C C 1 2' ... C1n et une résistance R11, R 1 2' ... R 1 n branchées en parallèle, ces résistances pouvant inclure les pertes des inductances et des capacités. Each parallel resonance circuit includes an inductor L11, L12 ... L1n, a capacitor CC 1 2 '... C1n and a resistor R11, R 1 2' ... R 1 n connected in parallel, these resistors can include the losses of inductors and capacities.

Chaque circuit à résonance série comprend une inductance L21 L22, ... L2n une capacité C21,
C22, ... C2n et une résistance R21, R22,--- R 2n branchees en série entre deux circuits à résonance parallèle successifs, ces résistances pouvant inclure les pertes des inductances et des capacités.Each series resonance circuit includes an inductor L21 L22, ... L2n a capacitor C21,
C22, ... C2n and a resistor R21, R22, --- R 2n connected in series between two successive parallel resonance circuits, these resistors can include losses of inductances and capacitors.

La première cellule 8 du filtre est connectée aux bornes de l'impédance de charge de l'abonné Za, le générateur G de signaux de telémesure étant connecté en parallèle sur la charge Za, en série avec une capacité d'injection Ci. The first cell 8 of the filter is connected to the terminals of the subscriber load impedance Za, the generator G of telemetry signals being connected in parallel to the load Za, in series with an injection capacity Ci.

La dernière cellule 10 du filtre est connectée aux bornes de l'impédance ZR du réseau en série avec l'alimentation à 50 Hz, 220V fournie par celui-ci. The last cell 10 of the filter is connected to the terminals of the impedance ZR of the network in series with the power supply at 50 Hz, 220V supplied by the latter.

Il est à remarquer que toutes les branches et en particulier les branches situées aux deux extrémités du filtre sont constituées par des circuits résonnants amortis dont les fréquences d'accord sont différentes. It should be noted that all the branches and in particular the branches situated at the two ends of the filter are constituted by damped resonant circuits whose tuning frequencies are different.

Le filtre ainsi constitué permet d'obtenir les avantages suivants. The filter thus formed provides the following advantages.

- Une forte impédance d'entrée coté abonné, afin de ne pas perturber le signal de télécommande. - A high input impedance on the subscriber side, so as not to disturb the remote control signal.

- Une faible impédance de sortie, coté réseau, ce qui protège 1-' abonné contre un éventuel signal perturbateur externe et limite les rayonnements. - A low output impedance, on the network side, which protects the subscriber against a possible external disturbing signal and limits radiation.

- Possibilité de mise en cascade sans interaction entre cellules. - Possibility of cascading without interaction between cells.

- Possibilité d'optimiser les fréquences d'accord des branches du filtre en vue d'élargir au maximum la bande atténuée. - Possibility of optimizing the tuning frequencies of the branches of the filter in order to widen the attenuated band as much as possible.

- Indépendance des performances vis à vis des variations des impédances, de charge des deux cotés du filtre, dans le cas de l'utilisation projetée. - Independence of performance with respect to variations in impedances, load on both sides of the filter, in the case of the intended use.

De plus, contrairement aux filtres classiques, les coefficients de qualité des inductances L et L2i sont très faibles ce qui équivaut à placer dans la structure les résistances R li et R 2i aboutissant au schéma de la Fig.2.  In addition, unlike conventional filters, the quality coefficients of the inductances L and L2i are very low, which is equivalent to placing the resistances R li and R 2i in the structure, leading to the diagram in Fig. 2.

La structure ainsi obtenue est profondément dissymétrique et ne fonctionne que dans le sens du montage indiqué sur la Fig.2. The structure thus obtained is deeply asymmetrical and works only in the direction of assembly indicated in Fig. 2.

Afin d'améliorer les performances du filtre, on utilise pour sa constitution des composants qui supportent l'application de fortes puissances à 50 Hz. In order to improve the performance of the filter, components used to support the application of high powers at 50 Hz are used for its constitution.

A cet effet, les inductances sont du type à noyau magnétique en ferrite dont l'emploi est habituellement réservé à des applications hautes frequences. For this purpose, the inductors are of the ferrite magnetic core type, the use of which is usually reserved for high frequency applications.

Pour les inductances, y compris les inductances de puissance. on utilise du fil fortement divisé. For inductors, including power inductors. strongly divided wire is used.

Le calcul des composants entrant dans la constitution du filtre de la Fig.2 est un calcul complexe d'optimisation qui prend en compte les pertes réelles des composants (résistances R . et R R2i) et
1i 2i détermine les fréquences d'accord optimales des différentes branches.The computation of the components entering into the constitution of the filter of Fig. 2 is a complex optimization computation which takes into account the real losses of the components (resistances R. And R R2i) and
1i 2i determines the optimal tuning frequencies of the different branches.

La méthode de calcul utilisée consiste en une formulation du problème permettant une succession de contraintes linéaires enveloppant les contraintes non linéaires. The calculation method used consists of a formulation of the problem allowing a succession of linear constraints enveloping the nonlinear constraints.

Les contraintes linéaires sont alors résolues par la méthode du simplexe appliqué à la formulation duale.  The linear constraints are then resolved by the simplex method applied to the dual formulation.
