Re: Controlling load of the generator

I dont have it set up yet, I am just trying to figure out the easiest way around it.

I found the efficiency curve of this kind of a turbine. Its from a book dated some 60 years back when american team done some testing on it.



So it seems it has quite good performance at partial flows, but has narrow rpm sweet spot.

And since I want everything I can get from my water , I would like to run it at that speed for all the different flows I get. And I figure that making load onto the turbine would be easier electronically than to build a transmission.

In the end I will probably figure out that it is the best to just contact a firm that makes these and order the whole setup in one package.
