5 Intended engineering process with SCL
5.1 General
Engineering of a substation automation system may start either witn the alocaiion ot functionally pre-configured devices to switch yard parts, products or functions, or with the design of the process functionality, where functions are allocated to physical devices later, based on functional capabilities of devices and their configuration capabilities. Often a mixed approach is preferred: a typical process part such as a line bay is pre-engineered, and then the result is used within the process functionality as often as needed. For SCL, this means that it must be capable of describing:
a) a system specification in terms of the single line diagram, and allocation of logical nodes (LN) to parts and equipment of the single line to indicate the needed functionality:
b) pre-configured IEDs with a fixed number of logical nodes (LNs), but with no binding to a specific process — may only be related to a very general process function part;
C) pre-configured IEDs with a pre-configured semantic for a process part of a certain structure, for example a double busbar GIS line feeder, or for a part of an already configured process or automation system;
d) complete process configuration with all lEDs bound to individual process functions and primary equipment, enhanced by the access point connections and possible access paths in subnetworks for all possible clients;
e) as item d) above, but additionally with all predefined associations and client server connections between logical nodes on data level. This is needed if an lED is not capable of dynamically building associations or reporting connections (either on the client or on the server side).
Case e) is the complete case. Both cases d) and e) are the result after SAS engineering, while case a) is a functional specification input to SAS engineering, and b) and C) are possible results after lED pre-engineering either for a typical usage of the lED, or for a specific usage within a project.
5.2 Scope of SCL
The scope of SCL as defined in this standard is clearly focused on these purposes:
1) SAS functional specification (point 5.1 a) above),
2) lED capability description (points 5.1 b) and 5.1 C) above), and
3) SA system description (points 5.1 d) and 5.1 e) above).
These purposes shall provide standardized support to system design, communication engineering and to the description of readily engineered system communication for device engineering tools.
For practical purposes, the following is also supported:
1) exchange of system interfacing information between two projects handling two systems, which need to exchange data;
2) exchange of lED modifications on an lED instance engineered specifically for a project.IEC 61850-6 pdf download.
