Reminds me of my submarine days.

The electrical power plant consisted of 2MW turbine generators, 1.2MW
emergency diesel generator, 600KW motor generators, and a 10,000A/Hr
250V battery.

We had it easy. We had a synchronizer meter. It showed the running phase
difference between two machines. We ran the incoming machine a bit
faster than the running machine. The meter would run very slowly
clockwise. When the meter was at "11:00", clunk! we shut the breaker.
