What's a utility network¶

• Reference

A utility network is the main component users work with when managing utility and telecom networks in ArcGIS, providing a comprehensive framework of functionality for the modeling of utility systems such as

• electric
• gas
• water
• storm water
• wastewater
• telecommunications

It is designed to model all of the components that make up your system—such as wires, pipes, valves, zones, devices, and circuits, and allows you to build real-world behavior into the network features you model.

With a utility network, you can do the following:

• Create and edit features and objects that model every type of utility equipment.
• Discover how features and objects in the network are connected.
• Trace how resources, such as gas, water, and electricity, flow through the network.
• Provide an operational view of how all the dynamic devices of your utility are currently configured.
• Analyze how the network is affected by real-world events such as storms, outages, or equipment failure.

Visualize your network¶

• View thematic cartographic maps for different use cases, such as customer service, field collection and inspection, or distribution management.
• Create network diagrams that allow you to readily check network connectivity and create logical views of your network in a more simplified, symbolic representation of the information.
• View inside complex assemblies of devices and lines and manage how assets are connected within them.
• Visualize a selected pressure zone or circuit with a display filter.

Analyze your network¶

The utility network provides an array of analysis and tracing tools to support a large variety of analytic workflows:

• Perform inspection of the network in the aftermath of an event such as a severe storm.
• Determine the number of customers with access to your resource.
  • For example, you can create a load summary report to present the number of customers being supplied by a specific circuit in an electric network.
• Trace network features upstream or downstream from a given location.
  • For example, water utilities can determine which valves to shut off when a pipe bursts.
• Model multiple utility systems within one utility network and run tracing analysis across all of them.
  • For example, an outage from an electrical network can affect the delivery of another resource, such as gas or water. You can run a trace across all systems involved, see where the problems lie, and decide on the best course of action.

Structure of Utility Network¶

• Reference
• Intro of Utility Network

Five Layers in the Domain Network (specific by domain and commodity)¶

1. Device

   1. Points assets, Operational Configuration has a commodity value/cost value

2. Line

   1. Liner assets, like flows

3. Junction

   1. Points, but does not have operational properties. just for connectivity

4. Assembly

   1. A feature collection of equipment (e.g. a switch contains 3 wires)
      1. Logical connected features

   

5. SubnetLine

   1. e.g. circuit / logical representation

Three Layers in the Structure Network (regardless domain or commodity)¶

1. Structure Junction
   1. Points
2. Structure Line
   1. Line
3. Structure Boundary
   1. Polygon

Six Layers in the Utility Network¶

1. Subnet works
   1. Network Topology
2. Dirty Areas
   1. The Area contains errors, or new edit has occurred and out of sync
3. Point Errors
4. Line Errors
5. Polygon Errors
6. Service Territory
   1. Handle the data edit

Schema Comparison (Geometric Network vs Utility Network)¶

Utility Network¶

• 7 Feature Classes (E.g. Water Device)
  • Subtypes called Asset Groups: Major classification of feature class (E.g. Controllable Valve)
    • Asset types: Minor classification of asset groups (E.g. System)

• For me, Utility networks use the hierarchical classification system, like NAICS, here is the model structure difference

• Here is the field structure difference
  • Since Utility Network hierarchical classification system, the subtype inherent part of attributes from father type and also have their additional information (e.g. Controllable Valve here)
  • Hydrogen flag field in the geometric network is a true-false field

Data Translation toolset¶

1. Create Mapping Workbooks¶

• Define the mapping relationship workbook use this tool (transfer from geometric network to utility network)

2. Load Data from Workbook¶

General Data Migration Tools¶

• Workbench (hardcode the mapping relationship [gas])
