What is 61850?AN OVERVIEW


IEC Smart Grid Reference Architecture

Where does 61850 fit in?

Is 61850 a protocol, a standard, or what?

Framework for interoperabilitySubstation Data Model Suite of communication protocolsDefines performance in harsh environmentsEthernet based


IEC-61850 Substation Data Model


GOOSE (Generic Object Oriented Substation Event) MMS (Manufacturing Message Specification) SMV (Sampled Measured Values) FTP (File Transfer Protocol) WEB SERVICES (HTTP, XML, etc.)

IEC-61850 suite of protocols


IEC-61850 Performance Requirements


What were the Lessons Learned?EXPERIENCE WITH IEC-61850


Hardware design can be greatly simplified.Software design complexity is significantly increased.Network design is critical.

What design resources are needed?


TRADITIONAL IEC-61850


That depends on vendor implementation.

Examples: GOOSE Message Failure Indication from SEL-421:

S99_21LA.ANN.ASVGGIO4.Ind07 = S99_21LA_GSE_FAIL GOOSE Message Failure Indication from GE-L90:

S99_87LB.GEN.GGIO1.Ind6 = S99_87LB_GSE_FAIL

Is 61850 self-documenting?

NoMPRP used IEC-61850 equipment from multiple vendors:

• GE Proficy Driver Server w/ CIMPLICITY HMI• SEL Real Time Automation Controller• SEL 400 & 487 Series Protective Relays• SEL 2411 Programmable Automation Controller • GE Multilin UR Protective Relays• Qualitrol Intelligent transformer monitor• Beckwith Digital Tapchanger Control• Calisto Gas Monitor• MESA Battery Charger

Is vendor interoperability easy and are all 61850 IED’s interoperable?

Example MMS analog point:


More so than ever!New types of documents are necessary.Much of the hardwired complexity has moved to the software,

how will you document this?

Is documentation important?


GOOSE Message Maps


GOOSE Message Multicase Address Maps

IMAGE REDACTED FOR SECURITY


IED Logic Diagrams


SCADA & IED Data Maps


NoNew skills are requiredAdditional functionality creates added complexityClosely linking protection and integration functions via CID fileAdded 61850 computing overhead requirements exposed

weaknesses in protective relay, RTU & HMI platforms.

Does 61850 make integration simpler?


YesStandardization of specific hardware platforms and firmwareStandardization of specific software versionsAdded cost to track, evaluate and install upgrades

Is firmware & software control needed?


Not in all casesSome data not available via communication interfaceOther data needed to be remapped to make it available

Is all of the required data exposed?


Everything!!Device HealthDevice Communication HealthNetwork HealthTrip PathsMore problems or just better monitoring???

What do we need to monitor?


Do you need a lab?

Yes, a lab is essential!


YesTest SetsBrowsersNetwork AnalysisIED & SCL Config

Do you need different tools?


YesNetworksSoftware ToolsIEC StandardData Model

Do you need any training?


YesOnly way to ensure consistencyOnly way to capture lessons learnedOnly way to reduce costs through reuse

Are standards & examples necessary?


Is vendor support necessary?

YesIncreasing vendor count adds complexity & integration issuesVendor selection should include consideration of supportKey vendors for tools, RTU, & HMI must be willing to help with

problems encountered with 3rd party products


Yes on detailed design, hardware, and installationNo on relay and integration settings design & programmingNo on network design, hardware and supportNo on increased NERC/CIP compliance costs

Will we save money?


IEC-61850 is a multifaceted standard covering the full range of communication services necessary for substation automation

While physical design needs decrease somewhat, virtual design complexity increases dramatically

New documentation, tools, test beds, training, and vendor support are keys to project success

Opportunity for costs reduction, in particular with GOOSE.Opportunity for enhanced functionality and data collection.

Enhanced flexibility and expandabilityMore complicated to design and support

Conclusion


Thank You!
