1. CIMug Asset Health Focus Community
Update for Joint WG13/14 Meeting
January 20, 2015
Good morning, everyone.
I’m Pat Brown and I’m here to talk about the CIMug Asset Health Focus Community
This has been quite a week hasn’t it?
Kinda like sipping from a fire hydrant, isn’t it?
It’s been striking to me how often asset information featured in presentations we’ve heard this week:
On Wednesday
Siri discussed transmission and distribution transformer monitoring and health indexing
Matija spoke of including asset management data in the WEB.CIM integration platform
Gowri talked about a CIM-enabled Asset Registry
Alexandre addressed asset information in the analytics work that Hydro Quebec is doing
Yesterday
Shawn mentioned that assets are included in the UDM
And just this morning
And Fook-Luen just shared with us DTE’s asset risk management strategy
Feels to me like a real recognition of how the CIM can help in the domain of assets.

2. CIMug Focus Communities
Address:
A high-priority need
Where wide input is needed:
Utilities
Vendors
Universities
IEC WG experts
Supported by IEC WG Technical Team
Facilitate quicker, real-world-based updates of CIM standards
Asset Health is first, more are coming..
Let’s start by talking about the notion of focus communities…

3. Asset Management at Utilities
The Business Challenge
Aging fleet past design life
Limited resources
Increased regulatory / media pressure
Heuristic decision-making
Time-based maintenance is default
Replace?
Repair?
Monitor?
So back to the area of asset health.
Asset information is used for lots of purposes in a utility – capital accounting, rate-case preparation, work management, but one of the biggest untapped areas is using utility asset-related information of asset management itself.
Utilities are facing almost unbelievable challenges in managing their asset fleets x
Heuristic (seat-of-the-pants) decision making… something that is becoming less possible with the departure of seasoned utility engineers as the utility work force ages.
So there is a clear business need…
The Business Need
Accurate insight into asset health for accurate decision-making

The IT Challenge
Data location . .

test
Data format
Data stewardship
nameplate
inspection
Compounded by New Technological Opportunites
Modern sensing technologies
New communication solutions
In the typical utility, there is actually a wealth of existing information available that could shed light on the health of assets. The problem is getting to it in any kind of efficient fashion..
Compounded by the new available information ?
The IT Need
A way to organize disparate information from a variety of sources

And, of course the CIM would be the semantic model basis of choice to provide the organizing strategy for the Data Integration layers.
The AHFC has started by focusing on this lower integration layer and CLICK the enhancements to the CIM that will be needed to support it.

7. Asset Health Focus Community Work
Envision a CIM model-based architecture forming the basis of an asset health framework
Carefully review CIM support for asset health data and suggest refinements and enhancements to the asset- related portions of the CIM model
Resources
Real-world utility and vendor input
Technical support from WG13 and WG14
All that great structural support from the CIM is wonderful.. A really good starting point
But how to go about actually applying it to help with asset health information integration?...
So the AHFC started by envisioning…
And carefully reviewing
Getting real-world utility and vendor input all along the way…
Augemented by
As a matter of fact our habit has been to have alternative Tuesday phone calls by the two groups…
One Tuesday, one would…

8. Main Themes in Asset Health Information Sharing
Asset health data:
There are inputs to and outputs from analytics and they both need to be shared
Utilities have it and its stored all over the place
It comes in all different forms and formats
It is incomplete
It relates to both whole assets and to asset components

But how to go about actually applying it to help with asset health information integration?...

9. Main Themes in Asset Health Information Sharing
Asset health analytics:
There is a broad set of commonly used data (so standard modeling is possible)
There is great variety in data used for any given analysis
There is a ubiquitous need for history
Asset relationship to electrical network position is key

10. CIM Support for Asset Health Information
The skeleton is there
Asset and its components - Asset and AssetContainer classes, and their children
Nameplate – AssetInfo child classes
Model/Manufacturer – ProductAssetModel and Manufacturer classes
Test/Inspection/Maintanance Results – ProcedureDataSet child classes
Network model role – PowerSystemResource child classes
Measurements – Measurment and MeasurementValue child classes
… and concluded that:
But….
It needs fleshing out
It needs refinement

17. Asset Health Focus Community Sequence of Work Efforts
Did DGA data survey to “get our feet wet“
First modeling work - asset/asset component and nameplate/model/manufacturer
Started on Transmission breakers
Simple device, a few major variants, not run-to-failure
Next is procedure results
Future:
Support for history
Analytics outputs (condition, risk indices, rankings, etc.)
Planned or typical assets
Asset relationship to network role
Measurements
And we currently have a number of areas where extensions or improvements might be needed. They include
…really useful to describe a structure, a skeleton off which important asset information can be ‘hung’
…since the way in which one application might choose to arrange asset components for a given type of asset would have little probability of matching the way in which another application would do it

18. Asset Health Focus Community Work Approach
Methodically looking at UML
Data modeling guided by
breaker expert (vendor & utility) knowledge
goal of creating framework for plug-and-play analytics
thinking that informed existing CIM model
Inclined to add more than to change
And we currently have a number of areas where extensions or improvements might be needed. They include
…really useful to describe a structure, a skeleton off which important asset information can be ‘hung’
…since the way in which one application might choose to arrange asset components for a given type of asset would have little probability of matching the way in which another application would do it

19. asset/asset component
Not enough definition for analytic interoperability – need asset instance templates (are looking for best way to express them)
Define Asset child classes only when component relationships not supported by existing containment structure (InterrupterUnit, OperatingMechanism)
Use informative Medium and Bushing classes
Add
Asset.kind
Asset.lifecycleState
Modify
Asset.acceptanceTest->.baselineAcceptanceTest
Asset.initialCondition->.baselineCondition
Asset.initialLossOfLife->.baselineLossOfLife
Create new AssetPosition class

20. Asset Health Focus Community Work
Asset Instance Template Example – Bulk Oil Breaker
So let’s a quick look at what one of the templates we working on defining might look like.
Let’s take an SF6 Dead Tank breaker… one of the most common transmission breakers in service today…
What instances of what classes should be used to model this type of asset?
In the case of an SF6 Dead Tank Breaker, maybe we have:…
Template
Instances used to describe an asset of a specific type

21. Asset Health Focus Community Work – Common Breaker Types
Transmission
SF6 dead tank
SF6 live tank
Bulk oil (dead tank)
Minimum oil (live tank)
Air blast (live tank)
 Distribution
SF6
OCB
Vacuum
Air blast
Air magnetic
The intent is to develop templates for the most of common transmission and distribution breaker types… and then move on to transformers.

22. asset nameplate/model/manufacturer
Define AssetInfo child classes when nameplate information is typical for component (BushingInfo, OperatingMechanismInfo)
AssetInfo child class is always where nameplate information is modeled (move 5 nameplate attributes from Bushing to BushingInfo)
Add Asset to ProductAssetModel association to support distinguishing between asset-specific and model-specific nameplate information
And we currently have a number of areas where extensions or improvements might be needed. They include
…really useful to describe a structure, a skeleton off which important asset information can be ‘hung’
…since the way in which one application might choose to arrange asset components for a given type of asset would have little probability of matching the way in which another application would do it

23. asset nameplate/model/manufacturer (cont’d)
Add
SwitchInfo.ratedImpulseWithstandVoltage
SwitchInfo.ratedFrequency
SwitchInfo.ratedInterruptingTime
SwitchInfo.lowPressueAlarm
SwitchInfo.lowPressureLockOut
SwitchInfo.oilVolumePerTank
SwitchInfo.gasWeightPerTank
ProductAssetModel.styleNumber
ProductAssetModel.catalogueNumber
ProductAssetModel.drawingNumber
ProductAssetModel.overallLength

24. Asset Health Focus Community Work – Current Activities
Areas of UML under discussion
BushingInfo attributes
OperatingMechanismInfo attributes (and how they relate to some SwitchInfo attributes)
New ProductAssetModel attributes
Finalizing Transmission breaker templates
Investigating support for history
Planning for inclusion into IEC standards
We are looking to templates to
