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

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!

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 .

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.

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.

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

yes

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

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