How to migrate the geometric Network Electric data to Utility network?

Angiex__1 — Fri, 02 Feb 2024 08:14:04 GMT

I am having geometric network electric data, where i should have to migrate it to the Utility network, where i am stuck is that I don't know how to organize the Geometry network's feature classes to corresponding Asset Groups and Asset types in Utility network. As the words in the GN are different of that of the UN and i am finding what if i group them wrongly. Any suggestions or help that are recommended here?

Angie,

couple of suggestions. try not to think of it as a "right or wrong". There will be things you end up wishing you had done different but that is the nature of migrations and changes. An example of this from our migration would be the transformers. Ours are two terminal devices as they should be. We named the terminals as HIGH and LOW. I have situations in my model where we back feed the secondary blades on a standard conventional transformer. I now wish we had named them as LOAD and SOURCE. It is a small thing but in some of our integrations a such and from a terminology standpoint I feel it would be cleaner.

I would suggest becoming as familiar as possible with the UN model basics. @RobertKrisher from ESRI has a whole series of videos on these things that are targeted at initial migrations.

Second, I would suggest thinking of it in the light of how you want to USE your data. Examples would be. When we trace, we want to locate item X, or when we query by attributes, we want to know the difference in Y and Z.

If you want to set up a call to discuss some things message me here.

Take Care

@Angiex__1 I recommend you tackle this problem in two different ways:

The first and most important step to solving this problem, and it's a common problem, is to find yourself a subject matter expert (SME). That is to say that you should find someone in your organization who understands all the terminology in that model and who is familiar with your system (both the GIS and the real-world) and sit down with them and have them help you pick the right names for everything. If you are friends with an engineer or someone who spends a lot of time in the field, they are often an excellent resource for these kinds of exercises. The online data dictionaries also have descriptions for most of their asset groups and asset types, but since every utility company uses their own terminology and slang for their equipment its often difficult to parse that out into some of the industry standard classifications found in that model.

Second, let the model guide you. There are rules defined for everything, so if you look at the rules and look at your data (and how you've classified things) and the vast majority of your features don't match, you may have picked the wrong asset group/type. When you're ready to test your mappings I recommend you do a quick prototype of them (using the approach outlined in this presentation from IMGIS). Just map your asset groups and asset types and see how many errors you get. If you get thousands of errors saying that there aren't any rules for the features you've mapped, then you should go back to your SME and see whether the problem is with your data, the mappings, or maybe you just have some weird configurations in your data that you need to account for with additional rules.

Finally, if you get stumped this community is a great resource to get answers. You'll find lots of examples in this forum where people have asked how others are modelling specific types of equipment (meters in particular), so if you get stuck and don't see your question already on this forum then start your own thread!

Hi Robert, Thank you so much that you have taken time to give me a very brief answer regarding the migration of GN to UN, and I do have doubts regarding clearing the dirty areas, if you do have any suggestion that could make my work easier, can you suggest some?

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Mon, 04 Mar 2024 14:29:21 GMT

Can you be more specific with what you mean by clearing the dirty areas. Are you concerned about your data mappings being wrong? Overall data quality? Something else?

In general:

Create your data mappings
Work with your SME to get them as close as you can (rename and add asset type if you need to)
Review your dirty areas (topology errors) with your SME to determine the best way to resolve the errors.
Resolve the errors through data cleanup, configuration, and automation
Define subnetwork controls to accurately reflect your network sources/sinks so you can perform tracing and analysis

Steps 1&2 are covered in the data migration learning series I linked above, and steps 3&4 are covered in the connectivity and topology learning series, and step 5 is covered in the subnetworks learning series.

@RobertKrisher I have another doubt in subnetwork controller, is the water network necessarily have one subnetwork controller or multiples based on flow? in GN I have two source points and every time i run the trace in the Geometric network, the trace goes to either of the sources.

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Mon, 18 Mar 2024 13:02:48 GMT

Subnetworks are allowed to have multiple controllers. When you trace the system analyzes all the controllers for the subnetwork to determine the path upstream, downstream, or to isolate an area.

@RobertKrisher will it take a lot of time when Update subnetwork tool is running?

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Tue, 19 Mar 2024 14:27:34 GMT

@Angiex__1 The amount of time it takes to update a subnetwork has more to do with the size of the subnetwork than the size of the subnetwork controllers. That is to say, a subnetwork with a million features will take about the same time to update regardless of whether it has 1 or 100 controllers. Having said that, subnetworks with many controllers are more likely to be larger, but let's not let correlation imply causation 🙂

@RobertKrisher I have about 2,00,000 features and i have made only one subnetwork controller and it has been running for more than 15 hours already, should I be concerned?

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Wed, 20 Mar 2024 15:02:13 GMT

I'm not sure whether you meant to say 2 million or 2 thousand, but either way, it shouldn't take 15 hours. I recommend you open a case with support so they can see what is causing the issue (hardware, configuration, etc).

@RobertKrisher the subnetwork controller update worked, But i came across another doubt, In the GN we have a single way flow whereas in the UN we have two way flow for the water network, so my question is, will the UN trace be similar to the GN trace?

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Thu, 21 Mar 2024 13:46:15 GMT

The utility network calculates flow for water distribution systems using subnetwork controllers (pumps, towers, etc). Because water distribution systems are highly looped, and the actual flow varies based on the time of day, this is a more accurate way of tracing. If you perform an upstream trace it will show you the path(s) to all the pressure/water sources in your network. If you perform an upstream trace it will show you all the features downstream of your that location.

@RobertKrisher I made an error with creating the subnetwork, ending up making the whole region as the subnetwork , so if i have to make a particular region alone as a subnetwork i have to close all the valves that are closer to the region and update the subnetwork?

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Fri, 22 Mar 2024 14:13:54 GMT

@Angiex__1 You should only close or open a valve in the GIS if it's that way in the field, artificially closing them to try and reduce your network size compromises the integrity of your data. Water systems and gas systems can sometimes be quite large since they can contain multiple cities or entire regions, and everything that receives water or gas from the supply is part of that system.

If you have concerns about modeling such large subnetworks, your other option is to just focus on creating pressure zones, since they tend to have more manageable sizes.

Re: How to migrate the geometric Network Electric data to Utility network?

Angiex__1 — Sun, 24 Mar 2024 17:00:44 GMT

@RobertKrisher So creating different pressure zones will let me configure the specific area where I wanted to run the trace with respect to the subnetwork controller?

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Sun, 24 Mar 2024 17:13:18 GMT

@Angiex__1 When you run a trace that uses subnetworks it will perform the trace/analysis using the subnetwork controllers from that tier for the area you are analyzing. An easy way to know whether your trace uses a subnetwork is if you need to select a domain and tier, this is your way of telling the system which tiers' subnetworks you want to analyze.

Re: How to migrate the geometric Network Electric data to Utility network?

Angiex__1 — Mon, 25 Mar 2024 05:52:12 GMT

@RobertKrisher right now the issue im facing is that, i have to make atleast 2 subnetwork controllers, whereas when i made one subnetwork controller with the tier pressure 3000, the whole area takes up that tier and i just want only a partial region to take up that tier. But the whole area is included in the downstream trace.

Re: How to migrate the geometric Network Electric data to Utility network?

RobertKrisher — Mon, 25 Mar 2024 14:35:32 GMT

@Angiex__1 You need to identify ALL the regulators associated with that pressure zone and turn them into subnetwork controllers for that pressure zone. Once you've done that, the subnetwork will be properly constrained by its controllers. If you do now know which regulators belong to which pressure zones, you will need to talk to someone with a better operational understanding of your dataset.

@RobertKrisher Yes I figured out where i made the error, its in setting the terminal of the subnetwork controller and i have cleared it and it works perfectly, and also i have a doubt in reconciliation in branch versioning, is it mandatory for reconciliation to have enterprise version of 11.2 and advanced editing extension?
