Busy-type flat out today. I've just written up a 30 page screed on synchronous generation and the infinite bus. Interesting, no? Sync Gen is this super whizz-bang concept whereby power is supplied to your home via more than one power station, each operating multiple generators. Getting them to work in unison is quite the little process. There would be bedlam if all the generators weren't on the same wavelength. (One of the classic electrical gags, that.)
Conditions for Parallel Operation
If a generator is to be connected to a system arbitrarily, the generator is liable to suffer from severe mechanical forces and high electrical current as the generator attempts to match the system conditions. To avoid this, each of the three phases of the generator must have exactly the same voltage in magnitude, phase angle and frequency as that of the system to which it is connected. To achieve this match, the following conditions must be met:
- The magnitude of the line voltages of the two generators must be equal.
- The frequency of the generator and the system must be very nearly equal.
- The phase angles of the like phases must be equal.
- The two generators must have the same phase sequence.
All the wiser then? It's only the intro, but I'd be very surprised if when you read it, you didn't exclaim "Well, since you put it like that!"
And their kneebones must be connected to their thigh bones, no doubt.

Power? generators?
are you showing off?
fair enough - I'm impressed.
About 'power sources' - I would like to buy my power from an Australian owned company.No 'Texas Utilities' TXU/TRU, and not ORIGIN which is now owned by Singapore.
They could shut us off if they wanted to play dirty. Give me back the SEC and Gas & Fuel until I get my solar organised.

That's not a screed, that's art, man.

Thank you for sharing Tony. I'll keep all that in mind.

Gripping stuff. It's hard not to beg for more now...

synchronous generation and the infinite bus
I think I read that novel a few years ago. Douglas Adams, wasn't it?

So what is a tensor then?
Posted by: lemmy | 09 February 2006 at 21:32
Tensors are what happen to phasors when there is a full moon.

I'd still rather that hot chick from the speed-dating TXU ad tell me about that stuff.
Would make more sense somehow.

Watt's it?

Nice to see you put such important issue in your omh words Tony.

Us electrical types refer to it as the current vernacular.

C'MON! You conduit!

I used think electricity was boring but I think I may be doing a volte-face here. Shocking isn't it?
Posted by: Nabakov | 10 February 2006 at 12:34
yeah ok whatever. Hey will this be on the exam?

Wasn't "The Infinite Bus" a Rolling Stones song?

PS: Brownie, we still buy our power here from Western Power, one of those still-government-but-run-autonomously-until-the-inevitable-float entities. Every summer, they do a nice little collection of brownouts and blackouts when a million West Australians simultaneously turn on their airconditioners. And their pole fires - ten years ago, pole fires caused a disruption which wiped out Perth's entire power supply for the better part of two days.
Government power's not that great, honestly.

You may thinking of the Who's "My Generation."
The Stones did "All Down The Line" and "Sparks Will Fly".

I think some of us have our phrase angles wrong.

cannot believe Nabokov left out AC/DC High Voltage Rock n Roll.
and Bon has been gone 25 years.
seems like only yesterday.
