Jeremy, Not sure if this would work..... but.... How about feeding the hydro output into a large industrial battery charger or chargers. They are available in three phase. Modify the charger by eliminating the stepdown transformer. Basically what you need is a rectifier. Then feed the resulting DC to a conventional solar grid-tie inverter.
As Jay implied, it can be quite complicated and expensive to sync a hydro with the grid. The utility's typically require sophisticated protective relays which require annual testing by utility approved venders. The hydro I help service pays $1500.00 each time this has to be done. If you can find a way to do it using UL approved inverters, you may save everyone many tears. SMA Windy Boy and Power One wind inverter systems work in a similar way.

I guess kind of like a grid tie inverter, but AC in not DC input. Any ideas? Jeremy All Solar Inc.
