Hi wrenches, I have a site visit coming up on a hydro system, I believe its ~ 20 kW range, and an older unit, 30+ years old. This info may or may not be reliable until I see the site. However, I'd like some options to consider while I'm looking at their system. My hydro knowledge is weak but I enjoy it.
They experience browning out when certain loads kick on. I assume they have checked the diversion load controller(s) to see if its dropping and adding loads as it should. I also assume that they have checked the rotor assembly, brushes etc and they are in good working order. The first thing I'll do is call the manufacturer and see if they have any ideas, but I'm sure they will recommend a new turbine/generator assembly with better voltage regulation. I am wondering if there is any type of inverter can operate in parallel with the hydro output that can inject current (maybe VARS as well) onto the AC buss to help stabilize AC voltage and frequency during these events. It seems like the new smart inverters can do this but I have no experience with this. Maybe the Sunny Island? Im just starting to research this but I always appreciate your input. Thanks -- Mac Lewis *"Yo solo sé que no sé nada." -Sócrates*
