Thanks a lot for this. I don't have a model up in PSSE yet, but once I do I will try this out. Since the system is not 100 % radial I will need to check for direction of flow of power from the terminal to determine what are feeders and what are incomers. I like the check for island you did though.

Blockquote find the radial branches I'll use a trick here and employ some set theory. Radial buses are those that become islanded when the terminal station bus is taken offline Blockquote

This idea is good, and I think it is an elegant way of finding the the true radial consumers. But although radial for the most part, it is not purely radial and I want to catch also those that are not. Sorry for not being clear about this. I am wondering if instead it would be possible to look at the direction of flow of power to determine what are incomers and what are feeders.

I updated my question with an example report. Really appreciate the effort here!

Yes that's exactly right. Such a system is more radial and the purpose of the report to check that each bus (or switchboard) is correctly dimensioned, as well as to check the total load in order to size generators.

Thanks for the reply. Yes, P and Q for each consumer is a good start. Is there an API to determine from which bus a load is powered from?

Hi, I work with an offshore distribution system and want to know if someone can point me to a python script that will create a load list? A load list will sort consumers according to the busbar that they are supplied from and show the power consumption of individual loads as well as the total load of the busbar.

The end report would look something like this

Report for Bus A

• Motor 10 kW
• Heater 20 kW
• Tranformer to bus B 10 kW
• Total for Bus A 40 kW

And then a new sections, or pages for the other buses (switchboards) in the case.

Best regards Bruce
