Definitions
- the present invention relates to the field of low- voltage switchboards. More in particular, the present invention refers to a communication network for low- voltage switchboards.
- low-voltage switchboards i.e. for voltages lower than 1 kV AC or 1.5 kV DC
- switching devices comprise one or more electrical poles, associated with each of which there are at least one fixed contact and one mobile contact, mutually coup lable/uncoup lab le by means of the operation of suitable control means.
- electronic protection devices also known as “electronic protection relays”
- the main technical purpose of these devices is to regulate the operation of the switching devices and to obtain information relating to the operating status of the electrical installation.
- a low-voltage switchboard generally includes a communication network designed to enable data/signals to be exchanged between electronic protection devices and the outside environment, and between different electronic protection devices.
- such a communication network comprises a principal communication bus (also called a system bus), the main purpose of which is to provide a channel for communications with the electronic protection devices.
- a principal communication bus also called a system bus
- the system bus is used to coordinate the operative functioning of the electronic protection devices and to acquire the data provided by the latter.
- system bus can be used by the switchboard operator to perform monitoring procedures on the operating status of an electrical line or to configure the operating parameters of the electronic protection devices.
- the aforesaid system bus traditionally implements communication modalities of the "master- slave" type, according to which the initiative for communication is taken by a device, such as a peripheral electronic device, for instance, or a supervisor and control system, that interrogates/activates the electronic protection device of interest (slave), with which it wishes to communicate, by means of a suitable interface made available by the latter' s control and protection unit.
- a device such as a peripheral electronic device, for instance, or a supervisor and control system, that interrogates/activates the electronic protection device of interest (slave), with which it wishes to communicate, by means of a suitable interface made available by the latter' s control and protection unit.
- the communication network of a switchboard is also developed at local level, i.e. at the level of each electronic protection device.
- the protection and control unit of an electronic protection device may be operatively connected, by means of a so-called "local bus", to additional electronic modules designed to implement additional functionalities.
- the protection and control unit generally has a "slave” port available for the additional electronic modules that act as "masters”.
- system bus is part of the communication network that is often subject to market demand for changes and adaptations
- any rigidity in the type of system bus available can be a factor responsible for the early obsolescence of the product on offer and even an obstacle to its saleability.
- a commonly adopted solution to enable a larger number of additional modules to be operatively connected to the protection and control unit consists in providing a further electronic module with two "master" ports between the protection and control unit and the additional modules.
- This further electronic module is designed to manage communication between the protection and control unit and the additional modules by means of a "polling" system for sorting the information in transit.
- the local bus thus becomes inadequate for use as infrastructure for protection and control functions that demand deterministic reaction times.
- the main technical aim of the present invention is to produce a communication network for a low-voltage switchboard that enables the previously-described limits and drawbacks to be overcome or reduced.
- one object of the present invention is to produce a communication network that ensures a performance of deterministic type, capable of meeting the data/signal communication needs from/to and between the electronic protection devices in a satisfactory manner, even when the number of electronic devices/modules connected to the communication network increases.
- Another object of the present invention is to produce a communication network that is highly flexible in use and that enables the user to modify the switchboard layout by means of the quick and easy installation of additional electronic modules.
- a further object of the present invention is to produce a communication network that is easy, quick and flexible to prepare and install in the switchboard at a relatively limited cost.
- the communication network comprises three distinct communication buses.
- a first and a second communication bus are designed to provide several communication channels for accessing the electronic protection devices from outside the switchboard.
- the first and second communication buses are associated with differentiated user access levels to enable the user to select who is qualified to become connected to each of the communication buses.
- the first communication bus hereinafter called the "system bus" for the sake of brevity, is associated with a first, lower user access level.
- the system bus can thus be used to perform monitoring procedures on the status of the network and electronic protection devices, and also procedures to configure said devices.
- the second communication bus hereinafter called the "switchboard bus" for the sake of brevity, is associated instead with a second, higher user access level.
- the switchboard bus can thus be used to place several protection and control units in communication with one another, and to perform specific automation and coordination functions.
- the switchboard bus can operate in known conditions, with a performance of deterministic type.
- the rapid and guaranteed response times of the switchboard bus enable the protection and control units connected thereto to share input/output signals and to implement automation logic of the PLC ("Programmable Logic Controller") type.
- the presence of a dedicated digital bus enables the protection and control units connected thereto to share articulated information that enables complex functions to be implemented, such as for monitoring the electrical network, coordinating the tripping of switching devices in the switchboard, or implementing control strategies to improve the management of electrical loads.
- the system and switchboard buses are associated with at least one third communication bus, hereinafter called the "local bus" for the sake of brevity, that is designed to place the protection and control unit of at least one electronic protection device in the switchboard in communication with one or more additional electronic modules, designed to integrate/extend the functions of the protection and control unit concerned.

- system bus and switchboard bus preferably communicate with the local bus, and consequently with the protection and control unit, by means of suitable electronic communication modules that function advantageously as "gateways".
- the communication network according to the present invention offers considerable advantages over the known state of the art.
- the communication network according to the present invention enables a sharing of the data/signal flows from/to and between the electronic protection devices, thereby ensuring a constantly high performance even in the event of high traffic volumes.
- the communication network according to the present invention is characterised by a great flexibility in use, from both the structural and the functional standpoint.
- the communication network according to the present invention has a relatively simple physical structure, that is quick, easy and flexible to prepare and install in the switchboard at a relatively limited cost, avoiding or reducing, for instance, any need for dedicated wiring.

- SCAD A Supervisory Control And Data Acquisition
- the switchboard bus 12 is associated with a second user access level, that is different and higher than the first user access level of the system bus 11.
- higher access level is used here to mean that access to the switchboard bus 12 is reserved for a more limited number of operators than the system bus 11.
- switchboard first 12 it may be advantageous to allow only "privileged" parties access to the switchboard first 12, i.e. those who can take higher priority action, such as the specialist personnel qualified to handle the so-called "servicing" of the switchboard.
- the system bus 11 can be used to access a more limited set of data/information 101 than the set of data/information 102 available via the second communication bus 102.
- an electronic access control device 80 can be advantageously connected to the switchboard bus 12.
- the switchboard bus 12 preferably implements a communication protocol of the
- Fieldbus type such as Can, or Ethernet.
- the preferred communication modalities in the switchboard bus 12 are of the "multi-master" type.
- the initiative for communication can be taken either by any of the electronic protection devices or other electronic devices operatively connected to the switchboard bus 12.
- the communication network 1 comprises a third communication bus 13 (the "local bus"), designed to provide a third communication channel between the protection and control unit 21 and one or more additional electronic modules 6A, 6B, 6C, 6E, 6F.
- a third communication bus 13 (the "local bus"), designed to provide a third communication channel between the protection and control unit 21 and one or more additional electronic modules 6A, 6B, 6C, 6E, 6F.
- These additional electronic modules can also be outside the electronic protection device 2 (like the module 6C, for instance).
- the above-mentioned additional modules can comprise, for example, electronic devices of analogical or digital type, suitable for expanding the inputs/outputs of the protection and control unit 21, electronic devices intended to provide auxiliary interfaces for the protection and control unit 21 (such as a display or a LED interface) and/or electronic devices designed to potentiate/expand the functions of the protection and control unit 21.
- the above-mentioned additional modules advantageously also comprise communication modules that provide an interface towards the system bus 11, or the switchboard bus 12.
- the electronic protection device 2 preferably comprises at least a first electronic communication module 6F, operatively connected between the system bus 11 and the local bus 13.

- the 6E is operatively connected to the protection and control unit 21 by means of the local bus 13 and is advantageously suitable for interfacing the protection and control unit 21 with the switchboard bus 12, whatever the communication protocol implemented by the latter.
- the local bus 13 preferably implements a communication protocol of the Fieldbus type, such as Can.
- the solution is particularly advantageous because several additional electronic modules (e.g. the communication modules 6B) can thus be operatively connected to one another so as to enable the expansion of the local bus 13 towards the next additional module, right up to the last additional module connected.
- additional electronic modules e.g. the communication modules 6B
- the communication modalities implemented in the local bus 13 are also preferably of the "multi-master" type, i.e. the initiative for communication can be taken by any of the additional electronic modules 6A-6FI operatively connected to the local bus 13.
- the protection and control unit 21 and/or one or more of the additional electronic modules 6A-6F preferably comprise first computerised means 213 and/or second computerised means 64, respectively, for the automatic recognition of the additional electronic modules operatively connected to the local bus 13.
- This solution is particularly advantageous because it makes it possible to connect different types of additional module to the local bus 13 (the only proviso consisting in that these modules be complete with a Fieldbus port) and enables the local bus 13 to be expanded without any conflicts.
- this enables the additional modules to be connected to the local bus 13 according to a "plug and play" type of modality, avoiding the need for any preliminary configuration of the electronic devices connected to the local bus 13 every time an additional module is connected/disconnected.

- the system bus 11 can advantageously be used almost exclusively to perform simple monitoring and configuration procedures, e.g. to record the operating status of the electronic protection devices 2, 2A and 2C, or of the electrical lines in the switchboard, or to send signals to the electronic protection devices (e.g. signals for controlling, enabling, tripping, and so on) or data/information (e.g. operating parameters) to set/modify the operating configuration.
- simple monitoring and configuration procedures e.g. to record the operating status of the electronic protection devices 2, 2A and 2C, or of the electrical lines in the switchboard, or to send signals to the electronic protection devices (e.g. signals for controlling, enabling, tripping, and so on) or data/information (e.g. operating parameters) to set/modify the operating configuration.
- the switchboard bus 12 serves instead as an effective tool for implementing higher- level functions in an extremely flexible manner, with a considerable reduction in the wiring of the switchboard and of the installation times/costs.
- the supervision and control unit 70 can be used to view data and parameters relating to all the electronic protection devices operatively connected to the switchboard bus 12.

- module 6C it is also possible to provide one or more additional modules, such as the module 6C, to perform protection functions based on information drawn from other electronic protection devices too.
- the switchboard bus 12 can be used, moreover, to exchange information relating to the electrical loads managed by the electronic protection devices in order to enable the implementation of "energy management" algorithms.
- Such algorithms can be implemented both inside the additional modules and in the protection and control units of the devices connected to the switchboard bus 12, and they enable the user to achieve a controlled disconnection of the loads in the event of overloads by tripping the corresponding circuit breakers on the basis of previously-established operating parameters, such as the priority of the electrical load to protect, the current passing through the electrical load, the effect of circuit breaking for the purposes of solving the overload situation.
- the continuity of the high-priority electrical line can thus be assured with the least possible overall impact on the section of electrical network managed by the electronic protection devices connected to the switchboard bus 12.
- the communication network 1 enables a high level of selectivity to be assured between two or more electronic protection devices in a far more flexible manner than with the solutions of the known state of the art.
- All the protection and control units connected to the switchboard bus 12 can exchange information relating to the protection logic they implement.
- a local web server can be made available and used to record measurements and set the parameters of the protection and control units, of any respective additional interfacing modules, and of all other additional modules included in an electronic protection device operatively connected to the communication bus 12.
- the switchboard bus 12 also offers considerable advantages when it comes to performing the so-called "network servicing" measures, since it becomes possible to manage the secure access to confidential data relating to the diagnostics of the electronic protection devices so that servicing measures of a predictive type can also be undertaken.
- the communication network according to the present invention is characterised by a marked flexibility in use (from both the structural and the functional standpoints) combined with a straightforward physical structure, and a quick and flexible preparation/ installation at relatively limited costs.
