Synchronizing AC generators -- Part 3 (sync and unsync)

[@memetb5796]

This instructor is fantastic. Not a single unnecessary word. Not a single fuzzy concept.

[@MrTuber7117]

I always wondered how, if at all, the utility companies connect themselves to the grid and run in "parallel". This is an awesome scale-model demonstration that makes it clear! Thanks for posting this!

[@Renizyne]

I like it how you deliberately set the VSD's slightly apart to illustrate a "real" life condition of let's say two steam turbines turning the generators rather than a VSD controlled motor. Excellent video!!!

[@mike_van_in]

I enjoyed all four of these videos on syncing. A very good job!

[@jetpower7992]

I always say a day that goes by not learning something is wasted thank you for the lesson.well done explaining in detail

[@kannanSairam]

wow ..amazing demonstration of the concept... love to see more similar topics

[@BTCInstrumentation]

Our plan is to have all six generating stations constructed, operational, and linked together on our own miniature power grid by the end of August 2014. Each generator will have its own overcurrent protective relay and SCADA node for monitoring certain variables. Expect to see plenty more videos by summer's end!

I would like to take a moment here by sharing my thoughts regarding your representation video, You Sir have earned all my respect for doing all this for free, I currently work as a testing engineer for MV panels and your method of sharing information for free is really admirable. for the time you have put in to wire up all these connections for the viewers betterment, I salute u and god bless you.

[@klazzera]

this is a great demonstration to explain generator synchronization, thanks a lot!

[@flaplaya]

Big reason UHVDC transmission interlinks are used I suppose. Great demonstration. Double trouble if a 180 degree shift were to happen..

[@tiborkiss9186]

wery clear explanation. Would it be possible to set up three relays or an arduino to lock them automatically once all lights out?

[@InfamousElGuapo]

Great Content!

[@GeorgeTsiros]

let's hear it for the person operating the stroboscope! 🤗 👏

[@Nibarger]

I just found this, but I am very impressed with the demonstration, presentation and overall explanation. I've been trying to read up on parallel generation and this is the first practical approach I've seen that makes it truly understandable. What is the difference if this was 1 phase generators? Thank you for posting this.

[@REXONCROSS]

perfect explanation ,i would like to see more videos about power

[@psy0rz]

please show what happens when you close the switch when they are slightly out of phase

[@itsezactually]

What happens when you turn the breaker on when they are out of phase?

[@no-damn-alias]

Can you show us what happens if you close the connection when the generators are out of phase

[@misiek08]

3 videos 4 minutes each better than 100 hours of lecture at university…

[@hassam4629]

can you please tell me that what type of motor you are using and the horsepowers?

[@vaderdudenator1]

What kind of load are these generator driving?

[@jasonbos1409]

I built a vibratory machine with two 3 phase motors that shakes media within a bowl. They don't stay in phase even with adjusting the frequencies. Can I apply this principal to my setup? If the eccentrics in the motors are opposing each other then I get destructive interference in the bowl and nothing moves until the motor phase up again briefly. Please help!!

[@ronblack7870]

that may damage the freq drives if you hook the outputs together. they don't put out clean sine waves. maybe 1 freq drive driving both motors .

[@Crestone-saju]

Nice demenstrution sir. Is it possible to couple two generator together with single pulley system. In that way it wouldn't reflect the rpm to synchronize? Just a thought

[@regaybahasht3770]

Is it work for single phase ?

[@ronblack7870]

yes

[@Qui-9]

Just curious how well this works when they are under significant load? I'm guessing the mechanical driving force must be very similar in order for this to work properly, otherwise they will each feel a very different portion of the load or try to fall out of sync?

[@floatingbonesjournal]

You asked at a good time! In early 2018, the European power grid experienced a significant imbalance. From arstechnica.com/tech-policy/2018/04/european-grid-dispute-resolved-lost-6-minutes-returned-to-oven-clocks/ "[...] between mid-January 2018 and early March, a grid dispute between Serbia and Kosovo resulted in 113GWh of unmet demand from Kosovo. Since Kosovo is part of the Continental Europe Power System, the unmet demand on the 25-country system led to a system-wide decline in frequency to an average frequency of 49.996Hz. That meant that clocks were counting down minutes too slowly, and, over three months, connected clocks around the continent lost six minutes." To fix the problem, the authorities pushed the system at 50.01Hz for a month. Unfortunately, this broke the clocks for the people who had already "fixed" them. And the authorities in Belgium decreed that This Shall Never Happen Again. I fondly hope that some science papers are being written about this incident.

Hi! Great material here. Is it possible to setup load sharing using this set-up as well? Thanks!

[@BTCInstrumentation]

Yes, load-sharing is possible to demonstrate with these machines. Once we get all six generators connected to our miniature "power grid" in the lab and get the SCADA system set up to display individual generator loads this will be a goal of ours: load balancing between individual stations.

[@egegasf11]

:) we would love to see a video of load sharing too !!

[@kyoteecasey]

if you're here by part 3 you don't need to explain the lights :| Good clear information though!

[@maxclark11]

120 degrees apart

[@stabilini]

Amazing explanation, would like more videos!! In 2019 an operational error in Argentina got out of synchronization multiples power plants leaving more than 50M people without electricity in a matter of 30 seconds affecting almost all Argentina territory, 100% Uruguay's territory, part of Paraguay and part of Brazil. en.wikipedia.org/wiki/2019_Argentina,_Paraguay_and_Uruguay_blackout

[@pratwurschtgulasch6662]

part 3 is like part 2, what is the difference. this guy just likes to talk talk talk but didn't even want to show a "slipped pole" too scared

[@ronblack7870]

he doesn't want to blow up a generator and the contactors.

[@jasonmurawski5877]

Those VFDs and generators are expensive, it would be a bad day to ruin one of them.
