Simple Power flow calc
Simple Power flow calc
(OP)
Hello :
I need information on performing a small power flow from a 3000 ft radial underground 12kv line to two small office bldg 5000 sq foot each. The client wants the study done with software.
I don't think he wants to model the complete utility system serving this bldg but maybe so. But I don't normally do load flow on small systems. I have done load flow on utility to many bldgs before using Dapper and Capper and Etap. but I don't have a license to use them any more.
What I specifically need to know is suggestions of any accepted industry practice of how to model the source if the source is unknown. If that is possible.
I also need information on an getting inexpensive software that is as easy to use as dapper and Capper( I also need to do some coordination curves)and Etap but except for small systems.
thanks

On the other hand, I have heard of, but don't remember the name of, nor know the capabilities of, an open source and/or freeware power system analysis package. So what you are looking for may exist, but whether or not it will be acceptable to the customer depends on their requirements.

I still need to know any accepted industry practice of how to model the source if the source is unknown. If that is possible.

I hope this will help someone else with thier design calcs.
Thanks all
