Abstract

Method and system arranged for configuring Intelligent Electronic Device, IED, process bus network switches from a substation specification according to IEC 61850 standard, said method comprising: calculating, from a substation topology file and from control function and substation bay library files, a Substation Specification Description file and substation traffic demand flow files comprising a GOOSE message profile subscription file and a Sampled Values message profile subscription file; generating destination MAC addresses; simulating the process bus communication network using said substation traffic demand flow files and process bus communication network topology, said topology comprising said process bus network switches, respective links and IED links; calculating the shortest path between each publisher IED and each subscriber IED; calculating a switch multicast filtering rule file, for each switch output port, comprising a multicast filter rule that allows the calculated shortest paths; translating the filtering rule file Into a file acceptable by the switch.

Claims

1. A method for obtaining an Intelligent Electronic Device (“

IED”

), process bus network switch filtering rule configuration file from a substation specification according to the IEC 61850 standard, comprising the steps of;

calculating, from a substation topology file, from a control function library file and a substation bay library file, a Substation Specification Description file and substation traffic demand flow files comprising a GOOSE message profile subscription file and a Sampled Values message profile subscription file;

generating destination MAC addresses;

simulating the process bus communication network using said substation traffic demand flow files and the process bus communication network topology, said topology comprising said process bus network switches, respective links and IED links;

calculating the shortest path between each publisher IED and each subscriber IED; and

calculating a switch multicast filtering rule file, for each switch output port, comprising a multicast MAC address filter rule that allows the calculated shortest paths.

2. The method as in claim 1, wherein simulating the process bus communication network further comprises simulating the bandwidth utilization and traffic profile in each communication link, further comprising the step of calculating for each switch output port a traffic policing rule or rules, in particular said traffic policing rules comprising priority reclassification policing rule and/or packet drop out policing rule.

3. The method as in claim 1, further comprising translating the switch multicast filtering rule file into a file format acceptable by each process bus network switch.

4. The method as in claim 3, further comprising performing said translation for each process bus network switch model/manufacturer combination.

5. The method as in claim 1, wherein the control function library comprises protection, automation and control functions.

6. The method as in claim 1, wherein the control function and substation bay library files comprise templates of standardized primary equipment names, PAC functions, logical nodes, and in particular corresponding data objects, according to the IEC 61850, virtual IED and corresponding critical traffic profiles publish and subscribe demands.

7. The method as in claim 1, wherein calculating a Substation Specification Description file comprises instantiating substation bays, instantiating substation IEDs, instantiating substation PAC functions and instantiating substation critical traffic profiles according to the IEC 61850 standard, wherein said instantiating processes comprises specifying, for said substation topology, all the PAC functions and corresponding IEDs that are required per substation bay according to said templates.

8. The method as in claim 1, wherein generating destination MAC addresses comprises the steps of:

using said substation topology, said instantiated bays, and said instantiated IEDs;

instantiating the GOOSE and Sampled Values traffic according to IEC 61850;

calculating traffic destinations of said instantiated critical traffic profiles; and

providing an available MAC address, for each calculated traffic destination, within a MAC address group corresponding to IEC 61850 Traffic Flow.

9. The method as in claim 1, wherein any one file of said files is a CSV file or any file combination of said files are CSV files.

10. The method as in claim 1, wherein any one file of said files is a XML file or any file combination of said files comprises XML files.

11. The method as in claim 1, wherein the GOOSE message profile subscription file comprises GOOSE publisher/subscriber pair and corresponding traffic parameters, comprising for each record of said file:

an id of the published GOOSE profile;

a name of the subscriber IED;

a type of GOOSE message;

a destination MAC address;

a VLAN Id;

a VLAN Priority; and

a T0 heartbeat interval;

according to the IEC 61850 standard.

12. The method as in claim 1, wherein the Sampled Values message profile subscription file comprises Sampled Values publisher/subscriber pair and the corresponding traffic parameters, comprising for each record of said file:

an id of the published Sampled Values;

a name of the subscriber IED;

a type of Sampled Values message;

a destination MAC address;

a VLAN Id; and

a VLAN Priority.

13. The method as in claim 1, wherein the switch multicast filtering rule file comprises for each record of said file:

switch Id;

switch port number; and

multicast MAC address.

14. The method as in claim 1, wherein the generating of destination MAC addresses comprises obtaining a MAC address attribution file, which comprises for each record of said file:

a multicast MAC address value;
