Abstract

A method and a system of control of power consumption of communications between electrical modules of an electrical infrastructure, including a star-shaped communication network between a central module, or master module, and a set of slave modules, the master module being set up to be connected to the slave modules by non-wireline communications links in a star pattern, and a processing circuit set up to regulate the power levels of communications links at least in a direction of reception by the master module from at least one slave module or by at least one slave module from the master module.

Claims

1. A method of control of power consumption of communications between nodes of an intra-substation or an inter-substations communication network of an electrical infrastructure, the nodes of an intra-substation communication network being formed by electrical equipment within the substation, the nodes of an inter-substations communication network being formed by the substations themselves, a node belonging to an intra-substation or an inter-substations communication network being called an electrical module, the method comprising:

defining a star-shaped communication network by partitioning the electrical modules between a central, master module and a set of slave modules, the master module being configured to be connected to the slave modules by non-wireline communications links in star pattern, and

minimizing power consumed during communication via communication links by regulating power levels of the communications links at least in a direction of reception by the master module from at least one slave module or by at least one slave module from the master module, said regulation of the power levels being processed according to a generic process modelling the communications links.

2. The method according to claim 1, further comprising regulating the power levels of communications links in a direction of transmission from the master module to at least one slave module or from at least one slave module to the master module.

3. The method according to claim 2, comprising:

regulating the power levels in the direction of transmission from the master module to each slave module,

regulating the power levels in the direction of reception of the master module from each slave module,

regulating the power levels in the direction of transmission from each slave module to the master module, and

regulating the power levels in the direction of reception of each slave module from the master module.

4. The method according to claim 1, comprising a modelling of communications links by ordered triplets each comprised of a first component indicating a direction of the communications link, and second and third components indicating a starting point and arrival point of the communications link in a forward order or in an inverse order according to whether the direction of communication assigned by the first component is respectively a transmission or a reception.

5. The method according to claim 4, wherein the regulation of the power level of a generic communications link identified by a first triplet having for its components a first direction of the communications link, a first electrical module, and a second electrical module, is realized according to a generic process comprising:

defining a second triplet having as its first component a second direction of the communications link opposite said first direction, as its second component said second electrical module, and as its third component said first electrical module,

iteratively testing an operating state of the communications link as a function of the first and second current values of regulation of power levels pertaining respectively to said first and second triplets while decrementing for each iteration a counter associated with the current value of regulation pertaining to the first triplet, said counter being initialized at a maximum power level value,

saving the first and second current values of regulation of operational power levels, and

saving a set of functional regulation pairs pertaining to the first triplet, each current pair of functional regulation being composed of said first and second current values of regulation of operational power levels.

6. The method according to claim 5, comprising saving a power consumption configuration according to a power consumption optimization strategy for the first module or the second module or a least power-hungry of said first and second modules.

7. The method according to claim 5, comprising performing a failure analysis of a communication in the event of a malfunctioning of the communications link.

8. The method according to claim 5, comprising performing a regulation in broadcast mode comprising selecting, from among the functional pairs associated with the communications links, a maximum level of transmission from the master module to each of the slave modules, as well as a maximum level of reception of the master module from each of the slave modules.

9. The method according to claim 1, wherein the control of power consumption of said master module and said slave modules is carried out after a predetermined event or during a critical situation.

10. A system of control of power consumption of communications between electrical modules of an electrical infrastructure, comprising:

a star-shaped communication network between a central, master module and a set of slave modules, the master module being configured to be connected to the slave modules by non-wireline communications links in a star pattern, and

a processing circuit configured to implement the control method according to claim 1.

11. The system according to claim 10, wherein the star-shaped communication network is an internal network composed of equipment within the same substation among which a central equipment unit is configured to be the master module while the other equipment units are configured to be the slave modules.

12. The system according to claim 10, wherein the star-shaped communication network is an external network including a set of electrical substations among which a central substation, or command centre, is configured to be the master module while the other substations are configured to be the slave modules.

13. An electrical infrastructure comprising the system according to claim 10.
