We are building a hydroelectric generation system for mining. As I understand, the frequency of the electricity generated (60hz)
might vary some, depending on how well we can regulate the valve feeding the turbine.

Is this a risk of frying the S19 miners?

How much variation do you expect? I'd suggest designing the system to keep within the PSU specs....

The specs show it can handle 47hz to 63hz ...
Have some dead Bitmain 17 series hashboards or full miners?
I'll buy them ... send me a PM with what you have and I'll make you an offer!

I have an idea
 You could convert the AC voltage from your generator into pure DC and then convert that into 220v AC with an accurate frequency

Some guy on the internet was getting +/- 3hz using a Arduino based feedback system for the water feed valve.
