utility-network-modeling's Issues

Overhead Three Phase Delta/Delta

An example of a distribution transformer delivering three phase power using three overhead single phase delta transformer units

Overhead Three Phase Sectionalizer, using distribuiton Transformer

Overhead Three Phase Recloser, low voltage connection to two distribution transformers on other poles

Overhead Three Phase Regulator, Platform

Overhead Three Phase Regulator Delta

Overhead primary meter

@jalsup , please review, particularly asset group/asset types.

Also, I found a typo in your type XLS. "Comercial Service Bank" should be "Commercial Service Bank"

Overhead Fused Single Phase Tap

Overhead Three Phase Capacitor, series, Fixed

Unfused riser tap

In discussion what to do with Risers, we need to sketch up.

We are currently discussing removing the riser junction. This would info would be moved to an attribute on a pole.

Overhead Single Phase Open Point, Not jumpered

Add terminals to devices in diagrams

We need to note and display terminals in the diagrams.

Instances for March 20 meeting

Matt, Rick, Erik, and Tom are eager to see initial instances from our work. They are not interested in the overall data model or asset packages, they want to hone in on reviewing the modeling patterns we are applying and discussing whether they are correct.

Examples are

• the pattern of having tap features for every phase
• the pattern of transitive structural attachments from containee features to structures
• how to model the transition from overhead to underground

I intend this to be a short term issue to rapidly review/revise/develop three instances for tomorrow. This will be quick and focused on tomorrow's meeting, so I won't (yet) upload PDFs into git, but I will share PNGs (from PDFs) in this issue.

My understanding from yesterday's meeting was three instances:

• Present the three phase wye transformer with riser instance, add a streetlight
• Present the unfused tap instance we've been reviewing on github
• I will work on a new instance today, summarizing the pole/crossarm and line/conductor story. This is the same that is in Tom's doc.

John just replied in email:
I wanted to make sure that we start with the connection point example you were going to draw up.

Next, we want to move to the unfused Riser.

Finally, I would prefer to start the transformers with a single phase dual voltage (connected to two phase on the high side)

The Three Phase example to me should either be last or presented at a later date.

Overhead Three Phase Open Point, Not jumpered

Overhead three phase wye transformer

I created a graphic from the overhead three phase wye transformer from the PPT, but I see three modeling issues:

1. I don't think the ground rod is connected properly, but I don't know the answer. The problem is that grounds are connected to the neutral wire (and ground terminals on devices) but we don't have a tap feature for neutrals.
2. Line end asset types are funky. This can't be right.
3. I thought we always had a riser at the junction between overhead and underground. Why is there no riser here?

Overhead Bidirectional Three Phase Recloser

Feedback from tom

1. No connectivity associations from line end to recloser assembly
2. Line ends would have structural attachment to pole
3. The single phase transformers are not energized from the arresters (look closely at the picture, they pull power off of the recloser device)
4. What’s also interesting (and we need confirmation) is a three-phase recloser is gang-operated and is a single device, not 3 unique assets (search various manufacturers and this is implied)
5. If modelling the connectivity associations from the controller back to the devices to avoid creating loops you have to have multiple terminals on the recloser device and no paths between the controller terminal to the terminals that provide connectivity to the lines
