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)
