WG10 Proposal:

Answer from Joerg regarding 6-100:For the brown field engineering, as well as for discussions about IED specification, the understanding of SSD and SCD file needs to be clarified. These files are not defined by their content, but by their role in the Engineering process.Some examples: • A Utility delivers as part of a specification an SCL file with only a Substation Section, even no Data Types: This is an SSD• The System Integrator is lazy and returns a file with only “as built” IEDs, Data Types and Communication Section: This is an SCD• A Utility adds a new bay to an existing SCD (brown field). And uses this as specification for the extension of the existing station: This is an SSD• A Utility creates a specification with Substation Section and Virtual IEDs. The Virtual IEDs are completely engineered (GOOSE, Reports, etc.) : This is an SSD• The System Integrator return an identical file, but “as built”: This is an SCDUp to now (SCL ED2 )the user has to know the meaning of the file. It cannot be derived from the content. 6-100 however is adding some semantics to the File:• An SCL file can have a GUID and a Semantic Version• An SCD can have a reference to the SSD that it implements• Each IED in an SCD can have o a reference to the ISD file, that was specifying ito a reference to the ICD, IID or CID file it is based on• Each virtual IED in an SSD can reference the ISD file it was specified with.

Short Proposal:

Add Part 6 a use case for extension to existing system from existing SCD. Add SICS for specification tool

Description

The engineering-processen is well defined for a green field / new IEC 61850 substation but needs clarification for refurbishment and extensions. In a green field project Vattefall starts by defining the SSD and hands it over to supplier as part of the bid for tender. Clarification of the process for an existing substation is required. Here utility needs to start by extending or modifying an existing SCD substation from original supplier. How are the modified parts of substation section handled? Can a SSD be created that maintains links to existing communication and IED structures, into which a new supplier can continue work? (61850-6:2009 clause 10 needs to define also "specification tool" besides system configurator. Can data flow engineering rights and SED files that be used for this use case?)
