Inter-bay substation automation application
View Patent ↗The present disclosure is directed to an exemplary interface description or structure of an inter-bay Substation Automation (SA) application. The interface of the application to other elements of the SA system, for example to a bay controller, IED, OPC server, HMI, and/or gateway, is examined to fully automate the inter-bay SA application configuration and implementation. A formal description or structure of the base SA system as for example, including an IEC 61850 SCD file can be used to generate a formal description of the interfaces of the inter-bay SA application to be engineered. Logical nodes can be connected to the process single line diagram and integrated into the SCD file of the base SA system, thereby generating an enhanced SCD file.
1. A method of implementing an inter-bay substation automation SA application involving primary devices arranged in a plurality of substation bays of a substation, comprising:
reading a standardized configuration description of an SA system of a substation, and obtaining therefrom a static topology of the substation as well as primary device information;
generating a coordination function block for control of the inter-bay SA application, and assigning, in the standardized configuration description of the SA system, the coordination function block to a coordination-level above a bay level, wherein the coordination-level is one of a voltage level or a substation level;
generating an interface function block for exchanging, over an SA communication network, data related to a substation constituent; and
assigning, in the standardized configuration description of the SA system, the interface function block to an interface-level respective of the substation constituent.
2. The method according to claim 1 , wherein the interface-level is one of a station level, a voltage level, a bay level, or a device level.
3. The method according to claim 1 , comprising:
engineering, based on an enhanced standardized configuration description of the SA system including the generated interface function blocks, application related communication flow between intelligent electronic devices (IEDs) of the SA system.
4. The method according to claim 1 , comprising:
generating a plurality of coordination function blocks for control of the inter-bay SA application; and
distributing the plurality of coordination function blocks on a plurality of intelligent electronic devices.
5. An intelligent electronic device IED of a substation automation SA system, for connecting to an SA communication network for data exchange with other IEDs, and hosting, comprising:
a coordination function block (LLN 0 , GAPC 1 ) for control of an inter-bay SA application involving primary devices arranged in a plurality of substation bays, the coordination function block being assigned, in a standardized configuration description of the SA system, to a coordination-level above a bay level; and
an interface function block for exchanging, over the SA communication network, data related to a substation constituent, the interface function block being assigned, in the standardized configuration description of the SA system, to an interface-level respective of the substation constituent.
6. The method according to claim 1 , wherein the inter-bay SA application is one of centralized switching sequence, transformer parallel control, transformer auto close, and load shedding.
