UCAIug Org Chart 2009
IEC 61850 (Edition 1)
• Part 4 : System and Project Management– Clause 7 : Quality Assurance
• 7.3.5 : Conformance Test
• Part 10 : Conformance Testing– Clause 5
• Conceptual test model• Use of SCL files
– Clause 6 : 61850 Abstract server tests– Clause 7 : Performance tests– Annex A : Detailed test procedure templates
IEC 61850ug Committee
• TISSUE database
• Maintain 61850 portion of theQuality Assurance Program (QAP)– Test Architecture (network based)– Conformance Building Blocks (CBBs)– Test report requirments
• Recommend extensions to standards
• Write “application notes”
Testing Committee
• Maintain lists :– Accredited testers– Conformance tested devices
• Maintain documents– Quality Assurance Program (basic)– Accreditation Procedure– Platform testing– Detailed Test procedures (ex: 61850 servers)
• Resolve interoperability disputes• Accredit (and annually re-accredit) testers
Testing Procedures sub-committee
• Collect testing needs from users/vendors
• Assist with abstract tests creation– 61850-10 has basic server abstract tests– Ex : “Verify can extract data dictionary”
• Create detailed tests from abstract tests– 61850-10 provides a template
• Name and purpose of test• References to standard clause(s)• Expected results• Test description
61850 Testing – What’s missing?
• Performance Testing : timing, accuracy, etc
• Inter-operability testing
• Plug-fests: but what is the purpose?– Technology demonstrations (this stuff works)– Vendor marketing (our stuff works)
• System (end-to-end) testing
• Environmental testing (EMC, etc.)
• Regulatory tests (ex: FCC emission tests)
Conformance vs. Inter-operabilty testing
• Definitions– Conformance : Does it meet every item in spec?– Inter-operability : Can it work with ANY
Conformance Certified device?
• Conformance != Inter-operability
Conformance vs. Inter-op testing (cont.)Conformance• Closed test• Negative Test• 1 “synthetic” others• Environmental testing
(EMC, temp, etc.)• Easy to prove result
Interoperabilty• Open test• Negative test• Many “real” others• Human environment
• Result dependent on “when” test was run
Both Conformance and Inter-op are needed– First verify each device Conformance
How 61850 can help OpenSG
• 61850 has already paved the path
• Templates– QAP addendum for 61850 exists– Abstract Conformance test procedures– Detailed Conformance test procedures– Distribute “the good word on tested products”
• Unfortunately, no interop testing done– UCAIug can assist with plug-fests– Virtual plug-fests?
Next Steps
• We are not starting from scratch
• Abstract / detailed tests already exists
• Re-organized to fit UCAIug mold?– Synergies between OpenSG and 61850 exist– This will involve additional work– Industry will see as a positive move– If we move, CIM may follow (good for UCAIug)
