powerflow, power-flow, or power flow?

powerflow, power-flow, or power flow?

powerflow, power-flow, or power flow?

Is power-flow, powerflow, or power flow the correct term for a numerical analysis of the flow of electric power in an interconnected system?

Wikipedia uses power-flow.

The NERC Glossary of Terms uses power flow in the definition of "Dispersed Load by Substations: Substation load information configured to represent a system for power flow or system dynamics modeling purposes, or both."

NERC also uses powerflow in the Procedures for Validation of Powerflow and Dynamics Cases.

RE: powerflow, power-flow, or power flow?

IEEE uses "load flow," so by extension I would assume IEEE would also use "power flow."

RE: powerflow, power-flow, or power flow?

I don't know the answer but I've had an interesting relationship with the subject.

I managed to make it through my four year EE degree without ever taking a single power course. (Some would say that's a sad excuse for an EE program, but I had plenty of fields, waves, signals, systems, and computers to make up for it)

Then about six years later I landed in a power plant engineering job where subject of "load flow" analysis to predict voltage at various buses during various conditions kept coming up in discussion, but I never understood what it really meant or why it would be a specialized analysis. (Why couldn't you just use the traditional circuit analysis techniques we learned in EE101 like the node voltage method or the mesh current method ? ) My boss was surprised when I told him I didn't know what load flow was, but he never explained it to me (at least not in a way that clicked) and I couldn't google it cuz google wasn't around yet.

A few years later I finally took my very first power course and it was a revelation to me (V-8 headslap). I had never thought about how you would go about modeling those pesky constant-power sources and constant-power loads in traditional circuit analysis (...you can't).

(2B)+(2B)' ?

Does it really matter?

If this were my document, my primary concern would be that the two words are not separated by a line or page break. In HTML, a non-breaking space is  . A non-breaking hyphen is ‑. In most word processors, you go [CTRL][SHIFT][SPACE] to do a non-breaking space. I don't know what a non-breaking hyphen is, which is what would keep me from using hyphens. God forbid I should read the docs. smile


RE: powerflow, power-flow, or power flow?

Xnuke- Thanks, I now see that the IEEE Taxonomy uses "power flow".

Drawoh-I had a spellcheck app flag powerflow as incorrect, but spellcheck apps often lack niche technical terms. In absolute metaphysical terms, it obviously does not matter at all. Relative to to value of other threads in this grammar forum, I hoped my questions was in the same ballpark of importance.

I am aghast at the idea of using a non-breaking spaces a general practice rather than confining them to being a specialized formatting trick. While I have used non-breaking spaces in very specific HTML pages, I have also wasted hours due to hidden formatting in files. Some specific pain points I have experienced with non-breaking spaces include:
1) Some find/replace programs treat the non-breaking spaces as regular spaces, whereas regular expressions treat non-breaking spaces as different than a standard space.
2) Copy/paste sometimes, but not always, converts non-breaking spaces to regular spaces.
3) The file format for my usual power flow program uses the space character as a field separator. Using a non-breaking space would combine two fields.
