Abstract

Telecontrol equipment for an MV/LV substation between a medium-voltage network and a low-voltage network. The telecontrol equipment including a first device configured to power the equipment from the low-voltage network and from an auxiliary source, a second device configured to communicate information gathered by the equipment to outside, a third device configured to monitor the medium-voltage network at the substation level, and a fourth device configured to monitor the low-voltage network at the substation level.

First claim

The invention claimed is:

1. Telecontrol equipment for an MV/LV substation between a medium-voltage network and a low-voltage network, the telecontrol equipment comprising:
first means for powering said equipment from the low-voltage network and from an auxiliary source;
second means for communicating information gathered by said equipment to outside;
third means for monitoring the medium-voltage network at a substation level; and
fourth means for monitoring the low-voltage network at the substation level, each of the first means, the third means, and the fourth means being directly linked to the second means by a series connection.

2. The telecontrol equipment according to claim 1 , wherein the first means and/or the second means and/or the third means and/or the fourth means are formed by a module comprising a casing housing electronic means for fulfilling a function of the respective first, second, third, and/or fourth means.

3. The telecontrol equipment according to claim 2 , wherein the electronic means comprise means for being updatable.

4. The telecontrol equipment according to claim 2 , wherein the third means are formed by a plurality of similar modules each comprising a casing housing electronic means for monitoring a line of the medium-voltage network.

5. The telecontrol equipment according to claim 2 , wherein each of the second, third, and fourth means comprise a casing provided with means for fixing onto a DIN rail and a profile of which is similar, said casings being attachable according to a constant pitch to form a row.

6. The telecontrol equipment according to claim 5 , wherein the first means comprise a casing provided with fixing means for fixing on a wall mount and provided on a face opposite said fixing means with a DIN rail onto which the casings of the second, third, and fourth means are installable.

7. The telecontrol equipment according to claim 5 , wherein the casings of the second, third, and fourth means comprise a nose opposite the fixing means for fixing onto the DIN rail, said nose comprising a human/machine interface to indicate main functions of the respective module.

8. The telecontrol equipment according to claim 1 , wherein the fourth means comprise electronic means for measuring current, voltage, energy, and/or power of the low-voltage network.

9. The telecontrol equipment according to claim 8 , wherein the fourth means are associated with a set of three current sensors placeable on a line of the low-voltage network, said three current sensors being self-powered, and communicating wirelessly with said fourth means.

10. The telecontrol equipment according to claim 9 , wherein the fourth means are associated with a plurality of similar sets of three current sensors, and the electronic means of the fourth means synchronize measurements of said sets of three current sensors such that the fourth means monitors a plurality of lines of the LV network.

11. The telecontrol equipment according to claim 8 , wherein the electronic means of the fourth means indicate a fault transition, monitor balancing of loads, and/or measure frequency in the LV network.

12. The telecontrol equipment according to claim 8 , wherein the electronic means of the fourth means monitor a transformer of the substation.

13. The telecontrol equipment according to claim 1 , further comprising series power supply connection systems from the first means to the second, third, and fourth means, the second means serving as relay for power supply for the third and fourth means.

14. The telecontrol equipment according to claim 1 , wherein said second means ensures communication within the telecontrol equipment and with the outside.

15. The telecontrol equipment according to claim 14 , wherein the second means comprise an electronic communication assembly and at least one cassette for communication to a management center, said cassette being removable and interchangeable according to medium and protocol used for the management center.

16. Telecontrol equipment for an MV/LV substation between a medium-voltage network and a low-voltage network, the telecontrol equipment comprising:
a first device including circuitry and configured to power the equipment from the low-voltage network and from an auxiliary source;
a second device including circuitry and configured to communicate information gathered by the equipment to outside;
a third device including circuitry and configured to monitor the medium-voltage network at a substation level; and
a fourth device including circuitry and configured to monitor the low-voltage network at the substation level, each of the first device, the third device, and the fourth device being directly linked to the second device by a series connection.

17. Telecontrol equipment for an MV/LV substation between a medium-voltage network and a low-voltage network, the telecontrol equipment comprising:
a first device including circuitry and configured to power the equipment from the low-voltage network and from an auxiliary source;
a second device including circuitry and configured to communicate information gathered by the equipment to outside;
a third device including circuitry and configured to monitor the medium-voltage network at a substation level;
a fourth device including circuitry and configured to monitor the low-voltage network at the substation level; and
series power supply connectors connected from the first device to the second device, the third device, and the fourth device, the second device serving as relay for power supply for the third device and the fourth device.
