1. CIMug Asset Health Focus Community
Update for European CIMug Meeting

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..

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?
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.
The Business Need
Accurate insight into asset health for accurate decision-making

4. Asset Management at Utilities.
The IT Challenge
Data location
field measurements .
Data format .
maintenance
test
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 ?

5. Asset Health Focus Community Work
Envision a CIM model-based architecture
Enables analytics
Supports enterprise-wide asset health insight
With real-world utility and vendor input
Define asset health use cases using IRM
Suggest refinements and enhancements to the asset- related portions of the CIM model
Create a data framework for:
Organizing data
Supporting analysis of what matters
Product development
Of course, the obvious answer is to model that shared data effectively in the CIM.
And that’s what the AHFC was set up to help do.
The work of the FC, which was started a little over a year ago, started by

6. Asset Health Focus Community Work
Typical utility practice
Aggregate data from multiple sources
Generate asset health and risk assessments based on the data
Generate asset health events when assessment indicates significant change in health conditions has occurred
Make data available to other systems/tools as needed/requested
The AHFC started out by exploring the existing asset health analysis environment at utilities…

9. Asset Health Information Modeling in the CIM
Overview of CIM Classes for Asset Health
61970
61968
Nameplate, Model, Manufacturer
Network Model
Asset Identity, Components
Asset Procedures, Results
Measurements

Another way to look at how the CIM supports asset health information modeling would be to look at an instance diagram. So, here is a typical asset, with it’s components. The diagram illustrates the CIM package (…list them…) that contains the classes used. And the instances reflect that same grouping of information we saw just a minute ago on the class diagram.

The AHFC is a collection of folks that are both CIM-savvy and not, so as a way to get started that was a bit more familiar territory than some of the esoteric CIM modeling “stuff”, we focused on a common procedure and result: DGA analysis of transformer tank oil. We did a survey and got a good feel for the typical information that is provided as a result. Which is good information which we can provide to the WG13/14 technical team.

But it also helped us realize that there was a foundational piece of modeling that we probably needed to tackle. DGA results relate typically to transformer tank oil. But should our interoperability model be associating those results with the transformer, the tank or the oil? And what about the difference between 3-tank and 1-tank transformers? How do those play in what you tack a DGA test result to? So, it seemed that clarifying the core part of the CIM model – the asset identify and component part (with some consideration of the nameplate, model and manufacturer part) was probably a really good piece of work to start on. ?

13. Asset Health Focus Community Work
Asset component ‘templates’ for common assets
Asset & AssetContainer usage
AssetInfo child classes
Starting with breakers

14. Asset Health Focus Community Work
Template Example – SF6 Dead Tank Breaker
What Asset and AssetContainer instances should be used to model this type of asset?
In the case of an SF6 Dead Tank Breake, maybe we have:…
Template
Instances used to describe an asset of a specific type

15. Asset Health Focus Community Work
Templates
Provide model-based way of organizing other asset health information (nameplate/model/manufacturer and procedure results)
Enable application interoperability
Will probably become IEC “Technical Specifications” not “International Standards”
A skeleton off which important asset information can be ‘hung’

16. Asset Health Focus Community Work
Upcoming activities
Identify common breaker types
Create draft templates for each breaker type
Based on community understanding of what information is available and what components merit modeling
Use existing CIM as starting point and suggest enhancements as appropriate
Document using Enterprise Architect instance models
Move to transformer templates next?

17. Asset Health Focus Community Work
Common Breaker Types
Transmission
SF6 dead tank
OCB dead tank
SF6 live tank
Air blast (live tank)
 Distribution
SF6
OCB
Vacuum
Air blast
Air magnetic
Have list of common breaker types.
Have starting point instance templates for several of those breaker types (but know they’re not right…)
