Anyone familiar with PowerFlow program?

Did you forget the message? If you are referring to a power system "load flow " program - yes, I am familiar with the beast. What is your problem?

Yes. Load flow. Just was trying to find a book on it. To find what its all about. A job I applied for was asking for experience using it. Which of course I have none.

-------------------- It will be covered in all power system texts since about 1970. Basic courses in power system analysis will also cover it. However, you won't get the necessary expertise from reading a text.
It is a method of solving for the the power flows and voltages in a power system given the various loads and generator powers/voltages. It boils down to the solution of a large number (sometimes several thousand) simultaneous non-linear equations. I won't attempt to give the form of the equations or the solution techniques in an e-mail. Efficient computer programs are available for this- given the program and the data- the idiot box does the work. However, the engineering judgement/experience comes into play when interpreting the results and deciding what adjustments must be made to the generation powers and voltages to improve overall system performance. This does require experience which will not be found in the books. You do not say what your background or the nature of the job. That might help. -- Don Kelly snipped-for-privacy@peeshaw.ca remove the urine to answer

Actually I have a EE but never worked as an engineer. Only in as technicians in electronics and telecomm. Early 40's now and that won't help my chances. A job I'm interested in was asking for power flow exper.
