System frequency varies 59.85hz and 60.10hz while charging

Hello I have a unique problem,

I work at a hydro plant that sometimes is islanded (not on system). We have to provide our own power with 100 year old generator units. The governor can't maintain a consistent 60.00 hz when not synced to the system.

I was wondering if the frequency varies from 59.85 to 60.10hz every 20 seconds would harm the Leaf while charging.

I don't think the OBC even really cares about grid frequency or can even measure it. As long as the voltage is correct and not sagging excessively I think you'll be ok.

A tesla on the other hand is a whole other story. They can actually measure frequency and are very sensitive to line voltage. I'm curious to see how one would react if it tried to charge from the island. I know roadster owners had a tough time charging from any generator that's not an inverter based genset, but that might have much larger frequency swings at startup.
