Find Radial Bus Paths
Added in the October 4, 2024 patch of Version 23
To access the Radial End Dialog go to the Tools ribbon tab, and choose Connections >Find Radial Bus Pathsfrom the Other Tools ribbon group. This dialog is shown here.
Click the Clear Radial Paths button to delete any Radial Bus Paths already calculated.
Click the Calculate Radial Paths button to perform a calculation that finds are sets of a Radial Bus Paths for the system based on the 3 options
Options for Calculation
Path Traverses Open Branches
Check this box to traverse open branches while searching for radial paths.
Treat Parallel Branch as Not Radial
Check this box to treat branches in parallel as a termination of a radial path. Uncheck the box to treat parallel branches as part of a radial path
Traverse Path by Bus or SuperBus
Choose to traverse by either Bus or SuperBus grouping. When traversing by SuperBus, then any branch that has terminal buses in the same Superbus will always show blank results for itself because the branch is not part of the path. Any Bus that
Bus and Branch Fields showing results of calculation
Once Calculate Radial Paths is chosen there will be entries in three fields for both a Bus and a Branch Object. These 3 fields are as follows
Neighbors\Radial Path\End Number (RadialEndBusNum)
If the bus is in a series path of buses (or Superbuses) connected to a radial bus, this will show the bus number of the final bus in the series.
Neighbors\Radial Path\Index (RadialEndIndex)
If the bus is in a series path of buses (or Superbuses) connected to a radial bus, this will show the index of it in this series of buses. The final radial bus will show a 1 as will branches connected to that final bus. The index will be one higher for each bus further away from the final bus.
Neighbors\Radial Path\Length (RadialEndLength)
If this bus is in a series path of buses (or Superbuses) connected to a radial bus, this will show the number of buses in the series path.
Example System
Consider the example below. Bus 51 and 31 are the primary bus inside their respective SuperBus groupings.
For this example we assume that all the branches in the image are closed as we assume the option for not traversing branches that are open is easy to understand.
The tables below however show what the RadialEndBusNum, RadialEndIndex, and RadialEndLength fields will show for the Bus objects in the first table, and the Branch objects in the second table. The columns show what these will under different options for the Traverse by Bus or SuperBus and how handle parallel branches.

The following image shows the radial path Buses and Branches when Traverse by SuperBus is chosen and Treat Parallel Branch as NOT radial is unchecked.
