Generators in parallel

[Classik]

Let's try something different now.

We were taught 500 years ago how to run generators in parallel. That is important when you have lots of load.

And one of the innevitable factors you must consider before closing the switch is ******* (without which your generators turn into a bomb when they aren't the same). What is that ******?

What other factors do you consider very important?

I play about with slight voltage variation.


Thanks

I remember us tinkering around 500 years ago. We learned to run generators in series, not parallel. Parallel is inefficient and potentially damaging to the generators.

May weaken them. Good ones should last

And when the demand for power is high? You go for a boost, don't you?

Both connections perform different tasks tho.

You just have to make sure that they are the same voltage, frequency, and are in sync before you close the switch between them.

Although some types of voltage regulation don't really lend themselves to parallel operation

The cheapest way to sync them is with light bulbs connected across the switch that is between the two generators you are trying to sync. You adjust the governor of the prime mover to change the speed until you get the lights to oscillate very slowly. Say a quick prayer, and during a long dark period you close the switch.

A long prayer is innevitable in all these operations .
Thanks alot. I knew you would respond here. Thanks again.

I'm more the electronic technician, but for a long time I was very leery of putting batteries in parallel let alone generators. Everyone knows that the strongest will discharge (like charging so-to-speak) into the weakest. I suppose you can place a diode between them to stop that action, as long as the one battery always remains the strongest (I'm not talking about a significant voltage differential here, but two batteries in parallel such as car batteries). It's not a configuration you want to keep together for a long time, that's for sure.

Reminds me of the superposition theorem days, but I'm talking DC. I won't even begin to entertain the idea of AC.

Electronics is indeed very interesting. (But I get upset and worried when troubleshooting takes a pretty long time. That's the reason I prefer building stuff from the scratch to troubleshooting problems)............As for AC... AC is usually a big problem, very unfriendly and boring.

I would not say AC is boring --- at least it can resonate. Nikola Tesla did not think is was boring. :D

Awesome picturedsup
AC seems boring when it has to do with continous paperwork.

Few years ago I was nearly swimming in an AC of Over 10thousand volts. I didn't know the device could produce up to that.
